I need help with TORNADO2 linker (LD). I am using T2 under ObjecTime. ObjecTime is creating perl scripts to compile and link projects for x86(PC platform) and i960 targets.
ObjecTime has no problem creating output file for x86 but for i960 the linker has this problem (this is the output from the perl scripts, sorry):

.....

.....

It seems the linked thinks the i960 memory is only 65K. I am read the error messages right?
How can I solve this problem and tell the linker the i960 has 16 Mb ram, memory map?

Could be as simple as an improperly handled decrementer interrupt. Also, the loop itself could be causing an exception that ends up in checkstop. You may need to disable external interrupts during the loop to eliminate the first scenario. You may need to walk through the loop to catch the second scenario in action. Be sure the caches, TLBs, and BAT registers are properly initialized, even if MMU translation is disabled. Most of this stuff comes out of reset in a unknown state, so it has to be dealt with.

The function msg_open() successfully returns 6 different queue IDs. However, two of these queues IDs apparently are looking at the same msq_que structure causing confusion between the two queues. As an example, QID1 and QID2 both point at msg_que structure at 0x1ffea10. When a message is sent to QID1, both QID1 and QID2 think they receive a message. As a result, they each have 50% chance of picking up the message. Does anybody encounter this problem before? Or any ideas why VxWorks MqPxLib is reusing the message queue for a different queue ID? Any help would be much appreciated. Thank.

Message-ID: <8u9qai$3fp$1@nnrp1.deja.com> References: <39EF3331.152ABFCE@lucent.com> I've actually built the beast, including v3 support. You will have to build it outside of Tornado 2.0, and then refer to the library as an EXTRA_MODULE within Tornado. Part 1 ===================== Ill assume that $SNMP is the installation directoy of the epilogue stuff. Some of what is listed below is identical to section 5.2 of the getting started guide. 1. Copy the snark/vxworks/cfgs/wind.cfg to the $SNMP dir. 2. Edit it to make the two key changes: The first loadconfig statement in the file loadconfig 'vxppc' ;my system The SRCDIR setting: equate SRCDIR 'yourdirectory to the SNMP dir' ;would be $SNMP 3. Now, make sure you have copied $SNMP/snark/vxworks/h/snmpdLib.h to $WIND_BASE/target/h. Also, replace all contents of $WIND_BASE/target/h/snmp with $SNMP/snark/vxworks/h/snmp. 4. Run makmak in the $SNMP directory specifying this cfg file. 5. In the SNMP directory, type in "make all". If you get compile errors, try defining the following environment variables. I set them for my NT box with Tornado under C:\Tornado: WIND_BASE C:\Tornado WIND_BASE_TYPE x86-win32 WIND_HOST_TYPE x86-win32 Set these variables on an NT using the properties menu by right-mouse clicking over your 'my computer'. On this dialog use the environment tab. Open up a new DOS shell and try the make all again. Part 2 ====================== 1. Make sure you go to your BSP directory and edit config.h as per section 5.2 to add the defines BEFORE the configAll include. 2. Fire up tornado 3. Start a new vxWorks bootable image project based on this BSP. 4. Open up the build properties and click on the MACROS tab and find the EXTRA_MODULES. In the value field, add the full path and name of the snmp library. For some reason, it has no extension. 5. Rebuild all. That should do the trick. Now, if you actually are able to add a MIB to the agent let me know. I can add a MIB, but for some reason, none of my get/set routines ever get called.

Try putting a counter (count1) at the point after the semTake and another (count2) at the end of your task loop and you will find that they match (within a value of 1,of course). SemGive does not invoke your task, it just modifies the global semaphore as being taken such that the semTake if blocking, waiting for the semaphore will cause the task to become ready. the commio function will run in the context of the task that took the semaphore and another check on semTake will not happen until the current thread of execution completes and loops back to the semTake call.

But this certainly not due to any fault of the way the semaphores work!!!. Its for you to decide how your routine will handle this kindof scenario.

Message-ID: <3a096c81@news.bezeqint.net> Hi, We used the following components in our project: OS: VxWorks real time operating system. Working Environment: Tornado 2. Compiler: Diab-Data version 4.3g Board: MCP750 board with the PowerPC 750 (Motorola). The MCP750 board is connected to the monitor in the Tornado host (COM1 interface) via the RS-232 interface. Also, the board is connected to network lan via the ethernet interface, to enable image downloading. We do not want to connect this board explicitly to our Tornado host via the RS-232 interface, since we want to locate the board in the remote side. But, we want to enable monitor capabilities in our Tornado host (not via the shell tool, since we run our application from the Single Step debbuger and not from shell !!!) as we get when this board is connected via the RS-232 interface to the monitor in our Tornado host. The monitor is required for "printf" and "scanf" options which were executed in the application running in the board. Is it another way (maybe telnet ???) to enable monitor capabilities in our Tornado host from remote board ? If yes, how can i do it ?

Are you sure? The definitions you have are:- >typedef char *va_list1; > >#define va_start1(list,parmN) (list = (va_list1) ((char *)&parmN + >sizeof(parmN))) >#define va_end1(list) ((void)0) >#define va_arg1(list, mode) (((mode *)(list += ((sizeof(mode)+sizeof(int)-1) >& ~(sizeof(int)-1))))[-1]) These definitions are utter garbage. There is no way these functions could work on a PPC under the eabi calling convention because many of the arguments aren't even passed on the stack at all. Take another, closer look at the stdarg.h file. You will probably find that there's a #if 0 around those defintions, or perhaps a #ifndef VA_ something. With the GCC compiler, stdarg.h doesn't define those macros; they actually get defined in arch/ppc/toolPpc.h, which is included earlier than stdarg. Also, there is absolutely no reason to try and define things that the compiler does for you. It doesn't provide you with any advantage over letting the compiler do it, the only difference it can possibly make is that you can get it wrong if you haven't understood correctly what the compiler is doing.

The most likely cause of this is stack corruption or IRQ re-entrancy, I think. I'm fairly sure I remember someone else had a similar problem that came up here (comp.os.vxworks) sometime in the last six months or so, and IIRC the underlying problem was that they were doing something (printf, I think) so dreadfully illegal in their IRQ that it was making a mess of the foreground task. Does your IRQ do anything except the semGive? DaveK - -- They laughed at Galileo. They laughed at Copernicus. They laughed at Columbus.

Everything seems to be ok (interrupt 'end of DMA' occurs) but the buffer in memory is filled with 0xFF instead of the data I expect. Is a DRAM memory address seen from the PCI bus the same as the one seen from the processor ? Usually there is a PCI2DRAM_BASE_ADRS constant used to translate the address (on PowerPC BSPs for example). In the Pentium BSP, I couldn't find it so I assumed it was the same address (PCI2DRAM_BASE_ADRS = 0). Am I wrong ?

Organization: Bezeq International Ltd. Message-ID: <3a09a03c@news.bezeqint.net> Hi, I need to receive Ethernet frames before the IP layer receives them and then decide whether to transfer them to IP, drop them or both copy them to my application and transfer them to IP. The "VxWorks Network - programmer's guide" mentions Ethernet Hook functions (Chap. 14, pg. 209) that can be set for both receive and transmit and thus solve this problem. However, there is a note that says that this feature will not be supported in the future. I made a simple test and wrote 2 functions with the described prototype, that just do a "printf" (send or receive). Then I used etherInputHookAdd() and EtherOutputHookAdd() to install them. It seems like the output hook is working (although I can't say that for certain since this is only a very simple test), but I can't get the Input hook to work. I have tried many combinations, but with no success. I suspect that these features (or some of them) were already dropped, but I am not sure. Has anyone dealt with this problem before or know of another way to achive the same thing? My environment is: OS: VxWorks real time operating system. Development tool: Tornado 2. Compiler: Diab-Data 4.3g Board: MCP750 board with the PowerPC 750 by Motorola Attached is one sample of the code that I tried: - -------------------- start of code------------------------------------------ BOOL dec_ether_input_hook_func(struct ifnet *pif, char *buffer,int length) { printf("dec received\n"); return FALSE; } BOOL dec_ether_output_hook_func(struct ifnet *pif,char *buffer,int length) { printf("dec sent\n"); return FALSE; } STATUS HookDec21140() { int flags; printf("Setting hook input function to Dec Ethernet...\n"); if (etherInputHookAdd(etherInputHookRtn, "dc", 0) == OK) { printf("OK\n"); } else { printf("FAILED! error number: %d\n", ERROR); return ERROR; }; printf("Setting hook output function to Dec Ethernet...\n"); if (etherOutputHookAdd(dec_ether_output_hook_func, "dc", 0) == OK) { printf("OK\n"); } else { printf("FAILED! error number: %d\n", ERROR); return ERROR; }; printf("Switching to promiscuous mode DEC...\n"); if (ifFlagChange("dc0", IFF_PROMISC, TRUE) == OK) { printf("OK\n"); } else { printf("FAILED! error number: %d\n", ERROR); return ERROR; }; printf("Switching driver to UP mode (DEC)...\n"); if (ifFlagChange("dc0", IFF_UP, TRUE) == OK) { printf("OK\n"); } else { printf("FAILED! error number: %d\n", ERROR); return ERROR; }; printf("Setting driver flags (DEC)...\n"); if (ifFlagSet("dc0", IFF_PROMISC|IFF_UP) == OK) { printf("OK\n"); } else { printf("FAILED! error number: %d\n", ERROR); return ERROR; }; return 0; } - --------------------- end of code------------------------------------------ Thanks, DK --------------------------- Newsgroups: comp.os.vxworks Subject: Re: Doubt in VXWORKS OR TORNADO Queue Date: Wed, 08 Nov 2000 19:02:24 GMT From: vlam@JasmineNetworks.com Organization: Deja.com - Before you buy.

You can GIVE a sem inside an ISR if you wish. If the ISR wants to stack up gives, there are counting sems that can be given X times and then taken by another routine X times before the take blocks. Normal (binary) sems do not do this.

If more than one task can block on that semaphore, what happens if one is half-way through processing when the second one gets enabled (because the first didn't finish before the ISR called semGive() again)? Bear in mind that the second task might have its priority temporarily raised through the priority inheritance mechanism if you use this. It sounds like you may be relying on that semaphore to protect some memory or variables, but you have two tasks using them simultaneously and the second is over-writing the first giving the symptoms you see. Use a binary semaphore for event signalling and mutual exclusion semaphores to protect resources (memory or hardware) from being modified by multiple tasks at once. - - Andrew - -- Every great idea appears crazy to start with. --------------------------- Newsgroups: comp.os.vxworks Subject: Re: Tornado Compile Date Date: Wed, 08 Nov 2000 14:56:59 -0600 From: Andrew Johnson Organization: APS, Argonne National Laboratory Message-ID: <3A09BE1B.D0AE5826@aps.anl.gov> References: <3A09D143.D9863124@sympatico.ca> Mike McNaughton wrote: > > Is there any sort of compiler directive that will define present date, > time so that the run time can do something like a > printf("Compile Date,Time of this module was %s\n", COMPILEDATETIME); ? > > and get a result like ... > "Compile Date,Time of this module was 11/08/200 16:32 hrs" If you're using gcc, there are preprocessor macros __DATE__ and __TIME__ that should help: `__DATE__' This macro expands to a string constant that describes the date on which the preprocessor is being run. The string constant contains eleven characters and looks like `"Feb 1 1996"'. `__TIME__' This macro expands to a string constant that describes the time at which the preprocessor is being run.

If people respond to this from outside the US then I urge you to have a realistic view of salaries and conditions in the US. For a new graduate we are currently paying something around $60k, however we do make sure we get good people so that isn't necessarily the general rate and we are also in a moderately expensive area (East San Francisco bay). In the South Bay Area of California the poverty level is about $50k, rent on a one bedroom place will cost you from $650 per month in the north bay to a couple of thousand a month in the south bay. Three bedrooms are going to cost you from around $1500 to near $3000. I pay $1500 for three bedrooms, garage and 1.5 baths and I am considered lucky! Commuting from another area is going to take a long time, for example Alameda to San Jose for a 9am start will typically take two hours minimum or half an hour on Sunday morning :-) If you are thinking of buying then I hope you have a lot of money, a three bedroom house in the north bay is near a third of a million, in the south bay more than half a million. On the other hand if you get an offer outside Detroit Michigan or Denver Colorado then you shoud be able to afford a bigger house than you'll get on engineers wages anywhere else in the world, in New Hampshire $100k got a friend 2 acres and a three bedroom house in a very nice town, $200k will get you a small mansion and $300k will get you enough space for several horses and whole shed load of kids and all your visitors plus some woodland you'll never visit. If you have five years experience and you are looking in the Silicon Valley or one of the other areas then you need to be looking at $100k plus. I have 16 years and have three offers in the $125k to $140k range for San Jose, Cupertino and Redwood City but don't consider the crowding to be worth it. The rates in other towns aren't much different, chosing to live in the Bay Area will give you one of the easiest climates in the world but at significant cost to your general lifestyle. Also be aware of the legal situation, most non-resident aliens are on an H1-B visa and that is tied to one employer, however there have recently been changes to allow someone on an H1-B to go over to another company as soon as they have issued the H1-B paperwork. I believe they may also have secured the Green Card situation. Currently if you change company then the Green Card application has to be started again, they apparently changed that so that after six months it would continue so long as you stayed in the industry. If you take a job in the US make sure that the employer is going to sponsor your Green Card, for you it's freedom to be an ordinary person not beholden to a company, for them it's a cost. My company views this as fair exchange but others don't. Health care is not a luxury benefit, if your employer doesn't include health care then think long and hard, accidents happen and hospitals are incredibly expensive, the company should also offer dental cover which is also expensive. Food is cheap, fuel is around $1.50 to $2 per US gallon, electricity and gas are cheap enough to almost not matter. Eating out is also a trivial cost compared to somewhere like the UK Remember, if you just get in you can easly move, there are more jobs here for the technologically gifted than you could even think of and transfers, although difficult, are possible. In fact other employers will move heavan and earth if you are good :-) And finally, regardless of the incredible cost of living, the overcrowding, the earthquakes and the disruption of leaving home and moving to the states the only way I'm going back to the UK is in a box! This is a whole continent, after you have done your three or four years at the first company the world is your oyster, work in Florida and do Disney every night, go to Denver and ski half the year, go to Texas and wait for the Tornado! It's a hell of a country. paul In article <8u1pip$sm$1@news.vsnl.net.in>, "Gurpreet" wrote: >Dear Developers, > >I was wondering if anyone out there would be interested in good job offers >in the US. > >We are in need of professionals working on embedded systems in the following >areas: > >RISC/CISC processor/ controller architectures, Digital Signal Processors and >their peripheral devices, interface technologies like PCMCIA, CPCI, USB, >Firewire, SCSI, Operating Systems such as VxWorks, PSOS+, QNX, Windows NT/CE >and Linux, Board Support Packages and Device Drivers.

You shouldn't enable an interrupt unless you've installed a handler for it. Have you verified the SIMASK is being set to properly enable the interrupt? You can dump it out from the windSh with d vxImmrGet()+0x14,1,4 Bit 2 (using bit 0 as the MSB) is the mask bit for IRQ1, it should be a 1 to enable it. You should check the SIPEND to see if you have the interrupt pending, it's at offset 0x10 from the IMMR.

Kesti" Organization: MK Associates Message-ID: <3A0A3663.8B101FAC@gv.net> References: Reply-To: mkesti@gv.net "�輮��" wrote: >Could you tell me about the differencee??? I am going to interpret the question to ask "What is the difference between a BSP and a boot ROM?" A BSP, or board support package, is the code and documentation files that serve as the interface between a specific hardware set and vxWorks. Its code is where system initialization begins, device drivers are incorporated, and other hardware specific issues are handled. The BSP is used in a variety of ways. One of these is to build images of boot ROM's that can be programmed into EPROM and are installed on the target hardware. They provide the code that runs after reset, initializes the hardware, and attempts to load and execute an image of the operating system from a flash memory, disk, or network connection. They also provide the ability to interrupt the boot process and specify boot parameters that control where to find and hos to load that image. This is like interrupting a PC's BIOS with the DEL key, and configuring the Windows to boot in different ways. The BSP also serves as the basis for custom vxWorks images that can be built in a variety of ways to support different uses. They can, for example, be built to be loaded and executed on a target by its BSP boot ROM. Such builds typically include debugging support, allowing application programs to be loaded, executed, and debugged. Custom vxWorks images can also be built to provide still more boot ROM's. These typically boot the system in a specific way, as opposed to the configurable boot provided by the BSP boot ROM. These images might exclude debugging support but include debugged application programs that execute once the boot process is complete. - -- ======================================================================== Michael Kesti | "And like, one and one don't make | two, one and one make one." mkesti@gv.net | - The Who, Bargain --------------------------- Newsgroups: comp.os.vxworks Subject: Re: Ethernet Driver hook functions Date: Wed, 08 Nov 2000 21:39:56 -0800 From: DrDiags Organization: Posted via Supernews, http://www.supernews.com Message-ID: <3A0A38AC.61BCB43D@flashcom.net> References: <3a09a03c@news.bezeqint.net> Reply-To: drdiags@flashcom.net D.K, I cannot answer the reason why the EtherInputHook is not working, but I wanted to mention that you should treat your hook routines as though they were ISRs.

The project build might be slightly different, I guess the same principles apply as the do for a 5.3.1 style build. The boot process is somewhat contorted! The compressed bootrom is the most complicated, the others miss out certain stages but the principle is the same. The final vxWorks image expects to be loaded at RAM_LOW_ADRS (usually its code). If you use vxWorks 'boot ROMs' - which are a complete vxWorks image running a little command loop instead of the shell - they have to load to RAM_HIGH_ADRS so that the target area for the (network) load is free. Now executing from ROM is thought slow - especially as WRS won't enable the I-Cache for ROM - so the code that uncompresses/copies the image you want from ROM to RAM is itself copied to RAM before doing any useful work. If your image is linked to RAM_HIGH_ADRS then this code is linked to RAM_LOW_ADRS (and v.v.). However when execution starts the code is executing from ROM_TEXT_ADRS - which is not where the code is linked for. Any instructions that contain absolute addresses have to be fixed so the correct data is found - this is what the ROM_DATA() macro does. Fortunately much code is position independant (short jumps are PC relative etc) so only a limited number of places have to be fixed. (Do not compile any of the initialisation code with -m longcall - it will break!) If you are not executing from ROM, the final vxWorks image is included (possibly compressed) into a data array in the ROM image (binArrayStart to BinArrayEnd). When the boot code copies itself to RAM it avoids copying this area. This means that when it finally copies the image to its target it must be pulled from the ROM - not binArrayStart (which would be in RAM). If the initial image is linked to RAM_HIGH_ADRS, there must be enough DRAM for the entire ROM image to be copied to that address - including the target image - which is embedded in its data area. This might be an issue if you are trying to load a large image into a system with little RAM (or little RAM that the boot code knows of). Much of the source is common between the different boot types - hence some macros are null in some cases. > 1.For PPC860, _STACK_DIR == _STACK_GROWS_DOWN, is it right?

Look in $WIND_BASE/target/h/make - specifically defs.bsp and riles.bsp (or maybe, if you believe the comments - defs.project and rules.project). One of the following definitions is include in the final link: LD_LOW_FLAGS = -Ttext $(RAM_LOW_ADRS) LD_HIGH_FLAGS = -Ttext $(RAM_HIGH_ADRS) RES_LOW_FLAGS = -Ttext $(ROM_TEXT_ADRS) -Tdata $(RAM_LOW_ADRS) RES_HIGH_FLAGS = -Ttext $(ROM_TEXT_ADRS) -Tdata $(RAM_HIGH_ADRS) > > 3.But in case of ROM_COPY(that means VxWorks image(code+data segment) should > be copied to RAM), it is implemented by > > copyLongs ((UINT *)ROM_DATA(binArrayStart), > (UINT *)UNCACHED(RAM_DST_ADRS), > (&binArrayEnd - binArrayStart) / sizeof (long)); > > The STACK_ADRS and RAM_DST_ADRS seems to should be set by user.What is the > value of RAM_DATA_ADRS, RAM_DST_ADRS, STACK_ADRS in this case?

The issue is that the area being copied is embedded in the data area of another program - so its absolute address is unknown. What is more the data isn't even at binArrayStart - that is a RAM address - but in the ROM where the boot code copied itself from earlier! > > 4.In case of ROM_COMPRESS, > > first copy the data segment of uncompress routine > > /* relocate the data segment of the decompression stub */ > > copyLongs (ROM_DATA_ADRS, (UINT *)UNCACHED(RAM_DATA_ADRS), > ((UINT)binArrayStart - (UINT)RAM_DATA_ADRS) / sizeof (long)); > > Why not (end - RAM_DATA_ADRS)/ sizeof (long) > but (UINT)binArrayStart - (UINT)RAM_DATA_ADRS) / sizeof (long)? > It seems no sense. > This copy copies from the start of ROM to the required DRAM address. The length excludes the image - no point copying that to DRAM, might as well uncompress it straight to the correct play. As I recall there is another copy just following this that copies binArrayEnd..edata into DRAM as well (there is no guarantee that there isn't initialised data following the image. After this copy the code jumps via a function pointer to the decompress code. This is a carefully constructed absolute jump - to get into the RAM copy of the code. The entire boot process runs much, much faster if you enable the data and instruction caches for both DRAM and ROM. However you do need to ensure the data cache is flushed before executing copied code. You may also want to have an uncached alias for the ROM - eg for flash updates.

Suggest using logMsg instead of printf in these routines. Actually, you almost certainly did just answer why the input hook isn't working. The output functions are called directly by the task that is sending - that is the control flows from the task through the kernel send routine and into the device driver output function (through the hook, if installed, on the way), whereas incoming packets which may arrive at any time are caught by an ISR. The ISR calls the input hook before pushing the newly received packet onto the end of a queue for the tNetTask to deal with at a more convenient time. So output hooks would be expected to run in a task context and handle printf OK, but input hooks run in an ISR context and can't use most of the system calls without trouble. Presumably the manual advises treating *both* hooks as if they were ISRs just to be on the safe side. It's certainly good advice, in case they ever want to implement a mechanism for asynchronous sends where the foreground task just hands off the outgoing packet to be sent later by an ISR.

I think you should assume that the misbehaviour (restarting) of the routine that's doing the semTake is a consequence, rather than a cause, of the underlying problem here. So there's a few possibilities to consider here. Have you, as Bruce suggests, tried stackCheck to see if you've overflowed your stack? Are you sure your ISR correctly acknowledges and clears your interrupt ? Otherwise it would be returning and reentering almost immediately. This would slow the foreground task to a crawl, as the ISR would be running almost continuously. Or is it possible that you've mis-set the rate of the timer and it's interrupting a lot more frequently than it's meant to be? You mentioned in one of your other posts that you had a watchdog at the top of the routine. Do you mean an actual VxWorks WDOG timer? How have you initialised and started it? Have you applied the WRS patch that fixes the scheduler bug that can cause a low priority task to be scheduled ahead of a waiting higher priority task when an ISR returns? Let's see your source. If they're not immensely long, post the entire ISR and commio routines here, and we can all take a good look at the problem. DaveK - -- They laughed at Galileo. They laughed at Copernicus.

These macros are used in command lines in the build rules somewhere else in the makefile. The @ sign makes the command execute without the command line being printed to the screen. The rem command is one you may remember from BASIC: it comments out the rest of the line. So these lines specify that the LDOUT_CONV and LDOUT_HOST operations are no-ops for x86-win32 host.

The "watchdog" I mention is just a counter++ at the top end of my commio routine. When the OEM dumped this sytem on us, the commio IO routine was not running to completion between ISR's. Therfore , for want of a better solution, I split the Commio routine up using a switch(), case construct. That fixed that, at least treated the symptoms. The system has always been unstable, it would stall if I went away and left the shell open. Leaving stethoscope active was out of the question. Sometimes it stalls spontaneosously and causes a wreck on the rolling mill it is controlling. There is a function on the system that is supposed to measure eccentricity of a roll (on a steel rolling mill). I have just removed it altogether and will install this version of software today. The ecc. function did not work anyway. Actually I think that will fix our problem. It was computation intesive and was driven partly by the 2ms. ISR adn also by ISR's from 2-pulse tachs. There are about 12 subroutines which are called for each occurence semtake of the ISR's semGive semaphore. Immediatley before each subroutine call I've put : y[(x++) & 0xFF]= n; /*different n for each subroutine*/ y is an interger array y[256]. x++ & 0xff is a circular counter. The result is a ring buffer showing what the last 256 subroutines ran prior to the latest crash. The array gets printed to a hyperterm screen at the next reboot (reboot by pressing abort button on the cpu doesn't clear memory). What I see is that in about 1-case in 10, the ISR re-enters before all of the subroutines run. This is just in the aftermath of a reboot; not after a system crash. I am convinced that the cpu has been overloaded. I've alwasy suspected it just due to the fact that the ISR runs 500 times/sec. According to the OEM, our system differs from there other systems only in that it has the eccentricity function and it has a reflective memory / ethernet board. I really like the stackcheck() idea and will implement that today. This is the best users' group I've ever participated in. I've never been skunked in a request for advice on this group.

Date: Thu, 9 Nov 2000 15:37:14 +0000 (GMT) From: David Laight Organization: Lawrence Berkeley National Laboratory Message-ID: <200011091537.PAA15635@dsl-2.tadpole.co.uk> The project build might be slightly different, I guess the same principles apply as the do for a 5.3.1 style build. The boot process is somewhat contorted! The compressed bootrom is the most complicated, the others miss out certain stages but the principle is the same. The final vxWorks image expects to be loaded at RAM_LOW_ADRS (usually its code). If you use vxWorks 'boot ROMs' - which are a complete vxWorks image running a little command loop instead of the shell - they have to load to RAM_HIGH_ADRS so that the target area for the (network) load is free. Now executing from ROM is thought slow - especially as WRS won't enable the I-Cache for ROM - so the code that uncompresses/copies the image you want from ROM to RAM is itself copied to RAM before doing any useful work. If your image is linked to RAM_HIGH_ADRS then this code is linked to RAM_LOW_ADRS (and v.v.). However when execution starts the code is executing from ROM_TEXT_ADRS - which is not where the code is linked for. Any instructions that contain absolute addresses have to be fixed so the correct data is found - this is what the ROM_DATA() macro does. Fortunately much code is position independant (short jumps are PC relative etc) so only a limited number of places have to be fixed. (Do not compile any of the initialisation code with -m longcall - it will break!) If you are not executing from ROM, the final vxWorks image is included (possibly compressed) into a data array in the ROM image (binArrayStart to BinArrayEnd). When the boot code copies itself to RAM it avoids copying this area. This means that when it finally copies the image to its target it must be pulled from the ROM - not binArrayStart (which would be in RAM). If the initial image is linked to RAM_HIGH_ADRS, there must be enough DRAM for the entire ROM image to be copied to that address - including the target image - which is embedded in its data area. This might be an issue if you are trying to load a large image into a system with little RAM (or little RAM that the boot code knows of). Much of the source is common between the different boot types - hence some macros are null in some cases. > 1.For PPC860, _STACK_DIR == _STACK_GROWS_DOWN, is it right?

Look in $WIND_BASE/target/h/make - specifically defs.bsp and riles.bsp (or maybe, if you believe the comments - defs.project and rules.project).

The issue is that the area being copied is embedded in the data area of another program - so its absolute address is unknown.

The length excludes the image - no point copying that to DRAM, might as well uncompress it straight to the correct play. As I recall there is another copy just following this that copies binArrayEnd..edata into DRAM as well (there is no guarantee that there isn't initialised data following the image. After this copy the code jumps via a function pointer to the decompress code. This is a carefully constructed absolute jump - to get into the RAM copy of the code. The entire boot process runs much, much faster if you enable the data and instruction caches for both DRAM and ROM. However you do need to ensure the data cache is flushed before executing copied code. You may also want to have an uncached alias for the ROM - eg for flash updates.

Well, all that proves is that there's still stray pointers in the code, but by sheer luck they happen to end up trashing unused areas of memory; when they added the eccentric function, that meant the linker put things in different places in memory which had the consequence that the stray pointers were now stomping on something vital. 500 interrupts per second isn't all that much for a modern CPU.

I am >still waiting for someone at ACT to make since of this.. 'long long' is an integer, not a float also. The compiler only uses the floating point register because it's got (more than) 64 bits and the GP regs. only have 32 bits, so it's just handy to manipulate long long ints in a register that they can fit into rather than having to split them between two GPRs.

In this case, it's the binary semaphore used by tNetTask & netJobAdd. In my case, what happens is a bunch of packets have been queued up waiting for a DMA resource to become free. Once free, all of these queued packets are sent, and the DMA completion interrupt uses netJobAdd to have a task do the buffer cleanup. What I was noticing was that vxWorks was being rebooted!

This is very easy to do in a multi-tasking real time operating system. Especially when ISR's are involved. Unless there is a huge bug in the scheduler, giving a semaphore cannot change the program counter variable for a task. Semaphores can only affect the scheduling of your task, not the order of execution of a task's code. If your ISR is giving the semaphore more often than it can be taken, then sometimes the semGive will have no affect. So instead of taking the semaphore at 500hz, you take it at 250, 166.6, 125...

So long as you aren't holding the interrupts for a long time somewhere there shouldn't be a problem. void auxClkFunc (void) { /* faster to use the native type for the processor */ static int flag = 0; /* If flag is zero then set it to 1 and if 1 then it becomes zero */ flag = (flag==0) ? 1 : 0; /* put constants on the left of conditions and they can't be mistaken for assignments if you miss '=' */ if ( 1 == flag ) { your 12.5 Hz code } } Alternatively, and for slightly more pain, you could always set it to 12.5 Hz, you should find the source for syxAuxClkRateSet in your BSP. In the mcp750 BSP I have to hand they have actually got the AuxClk code in ravenAuxClk.c and rate is set by setting an integer then stopping and restarting the clock. The enable code actually applies the new rate and the few lines that do the damage are:- /* enable counter and write value to count from */ sysPciWrite32(MPIC_ADDR(MPIC_TIMER0_BASE_CT_REG), ((MPIC_TIMER_CNT/sysAuxClkTicksPerSecond) & ~(MPIC_TIMER_BASE_CT_CI))); The ticks per second count is an int so all you need to do is work out the rate using a float instead.

It works but its unreliable, crashing the system after a period of time that can be anything from a minute to a quarter hour of more. I've traced the problem to the cluster release function inside the stack which appears to be trying to release a NULL cluster (it doesn't check this so completely messes up the pool). This problem pops up in the VxWorks support materials but the reasons offered for the problem - overruning the cluster buffers, for example - don't appear to be the cause. Since this sort of material is often out of date I wonder if anyone has any more up to date information on this. I'm pretty sure its a bug in the stack, not the driver (the driver wasn't exactly bug free but is fairly easy to split the thing in two to verify that the basic transmission and reception mechanisms are solid).

Paul,

Thanks for that but I appear to have = misled=20 somewhat in my requirements. Although the process is to run at 12.5Hz it = has a=20 varibale length 'lead in' phase up to the 12.5Hz mark and it is this = 'lead-in'=20 phase that must be called (it in turn calls the 12.5Hz = process).

If you switch to a fixed width font = (e.g.=20 courier) it could look like this:

---------------------------|-----------------------> = time

.........|lead-in = runs =20 |12.5Hz process starts 1st schedule

...|lead-in=20 runs |12.5Hz = process=20 starts 2nd schedule

................|lead-in = |12.5Hz=20 process starts 3rd etc.

So, as you can see the 'main process' = always runs=20 @12.5Hz but the call I have to make 'jitters'. The 12.5Hz process = actually=20 returns a 'period until next call' to my routine (with an LSB of 100us! = :-o)=20 although I have been told that the 12.5Hz process can start at=20 12.5Hz + or - 1ms.

So I'm afraid, setting the clock to = 25Hz will=20 give me a 40ms 'tick' when I need a 1ms 'tick' or better = :-(

Thanks for the other stuff anyway - = it's good to=20 learn anyway.

While I wouldn't argue that a bug in the stack is out of the question, I would argue that it is far more likely a bug in the driver is at fault here. How do you suppose the stack obtained the NULL cluster? I would assume it was passed in by the driver rather than assuming the stack somehow created it.

This means they will have address values in the RAM range. The boot code however, knows that this part of the data segment does not need to be copied into RAM, so it leaves it in ROM.

The boot code is clever - it knows it does not have to copy ALL of the data segment to ram, only the part of the data segment that is not the compressed binary image.

It doesn't care how long the last invocation took. indeed, but if that rate is suitably high (e.g. 1000Hz) then I can make calls to ~1ms accuracy by deteremining how many 'ticks' will happen until the next schedule point (the point returned from the process). > So do you mean that you need to run a variable time before a fixed 12.5Hz > task? This sounds silly enough to be a military system :-) no, could be any commercial avionics/railways/automobile too :-) the 12.5Hz process has to be scheduled accurately, it has a bunch of messages to process before running. there can be a variable number of messages in the queue => a variable length of time is required before the 12.5Hz process is kicked off. It knows how many messages are in the queue at the end of its run and can therefore determine how long to be 'idle' for before the next invocation is required. > If you look at the code I posted you'll see that it's just setting a value for > a timer.

I would have a look at how the aux clock is implemented on you hardware. You may find that is compares a high frequency counter with a limit value, or decrements a counter at high frequence until it becomes zero. It is thus a simple coding exercise to make the interupt happen at an arbitrary time in the future - subject to the counter clock frequency and the accuracy of knowing when the start time is. This does, however, stop the aux clock hardware being used for any other purpose - you'll need an interlock against the std vxworks use of it. You may even find that your hardware has an additional timer you can use instead of the aux clock.

Ignore the manual and apply common sense! "CET::-60:032502:102802" will work fine! As will large offsets - you can set timezone offsets that go back (or forward) years, useful for making a program report that you finished something yesterday. (type TZ=GMT-12345 date to your unix shell!) What may not work (fix available from windriver support) is summer time in the southern hemisphere. Mind you this didn't work in many Unix versions until quite recently. What vxWorks doesn't support is a sensible definition of the summertime start/end (eg last sunday in october). Anyone running pJava will find it ignores the timezone offset and uses its own rules based on the name. None of the names gives the correct time for the UK in summer. GMT is always UTC+0, in the summer we have BST (ie the name changes, not the offset of the name from UTC. BST doesn't exist in the winter) the JVM thinks BST is somewhere just east of india (Bangladesh?). Indeed the JVM only has 24 names, some have summertime, some don't - none have southern hemisphere summer time. Mind you solaris behaves the same way if you give it an 'old' format TZ variable.

The traceback looks something like: > reboot > workQPanic > workQAdd0 > semFlushDefer > semGive > netJobAdd The 'problem' here is that the queues use to defer requests made in an interrupt routine until there is a proper context are easily filled. What you need to do is handshake your ISR and task code so that only one request to the task is ever outstanding. This requires a simple (volatile) variable. eg in the isr if (!kicked_task) { kicked_task = 1; semGive(...) ; } and in the task: semTake(...) kicked_task = 0; /* process all outstanding requests */ This way the ISR only wakes the task when necessary. Maybe netJobAdd should use the same technique to wake up tNetTask!

Ah. Then I'm mystified. I'd hazard a guess that the compiler does the same trick when 64 bit structures are passed by value, perhaps. I guess you'll just have to take the performance hit from running with VX_FP_TASK flag set. It might be possible to patch the compiler to stop it from using these doubleword operations, of course; and perhaps WRS should have done so (or added it as a -m option flag) when they made their other compiler modifications.

Date: Fri, 10 Nov 2000 15:58:47 GMT From: "Roy" Organization: Magma Communications Ltd. Message-ID: Hi there, I am trying to execute some tests on some cards (lets us call them slaves) each with their own IP's, and I would like to use the rcmd() function to send the command from one card (let us call it the central card). The problem is that I am not sure what is the best way to retrieve the information that is spit out by the slaves and send it back to the central card. This information is going to be the text that the tests that are invoked by the remote command, return to the VxWorks shell. The whole point of this is to have a centralized access point to retrieve test data from the slaves and send it back to the central card. I have read a lot about socket programming and would favour the use of some library (that I probably don't know about) to use instead of writing a lot of low level code from scratch. Does anyone know what is the best, or just 'a' solution is? Thanks in advance!

Message-ID: <8uh61n$4ks$1@nnrp1.deja.com> References: <8uecm0$q3g$1@nnrp1.deja.com> Hi Matthew, I expect you rely on the Windriver partition library to mount the disk. If you create the dosFs device starting with sector 1 of the disk, this is the first obstacle. We started some time earlier when the dosFs2.0 partition lib was not yet available and have some functions of our own to scan the partition table. So I cannot give any hints on using that part of the dosFs. However, even if you do the ...DevCreate(...) with the correct offset, than there are more pitfalls. From my experience with the dosFs2.0, I knwo this library to do a lot of checking on the contents of the MBR and the partition boot sectors. The rules for these checks seem to go back to the very early days of DOS and might fail with a disk formatted on a Windows 98 system. You might try to format your disk with a Windows 95 system. That definitely works.

Yes, and if you do it well it should take negligable time on most modern processors. One of the more Highly Priced printers on the market runs the system clock at that sort of rate. There are many ways to skin this particular cat. How long before the next 12.5Hz task do the mesasges arrive? Can you run a 100Hz clock and flush the queue in 3 out of 4 invocations and run the 12.5Hz task, after flushing again, on the fourth? >> So do you mean that you need to run a variable time before a fixed 12.5Hz > >> task?

In any case if you set the system clock to a multiple of 12.5Hz you can release that task on a watchdog and then you are free to use the aux clock to do whatever you like and you won't lose track. For example turn the system clock up to 100Hz and set the watchdog timer to 8 each time. This (probably) isn't rocket science. speaking of which, the RAD6000 processor on the Mars Pathfinder could run the system clock very fast (lots of kHz), if you can only run relatively slowly then I'd suspect that either your are running on an 8051 (only joking) or there is something wrong elsewhere.

I would have a look at how the aux clock is implemented on you hardware. You may find that is compares a high frequency counter with a limit value, or decrements a counter at high frequence until it becomes zero. It is thus a simple coding exercise to make the interupt happen at an arbitrary time in the future - subject to the counter clock frequency and the accuracy of knowing when the start time is. This does, however, stop the aux clock hardware being used for any other purpose - - you'll need an interlock against the std vxworks use of it. You may even find that your hardware has an additional timer you can use instead of the aux clock.

Ignore the manual and apply common sense! "CET::-60:032502:102802" will work fine! As will large offsets - you can set timezone offsets that go back (or forward) years, useful for making a program report that you finished something yesterday. (type TZ=GMT-12345 date to your unix shell!) What may not work (fix available from windriver support) is summer time in the southern hemisphere. Mind you this didn't work in many Unix versions until quite recently. What vxWorks doesn't support is a sensible definition of the summertime start/end (eg last sunday in october). Anyone running pJava will find it ignores the timezone offset and uses its own rules based on the name. None of the names gives the correct time for the UK in summer. GMT is always UTC+0, in the summer we have BST (ie the name changes, not the offset of the name from UTC. BST doesn't exist in the winter) the JVM thinks BST is somewhere just east of india (Bangladesh?). Indeed the JVM only has 24 names, some have summertime, some don't - none have southern hemisphere summer time. Mind you solaris behaves the same way if you give it an 'old' format TZ variable.

What you need to do is handshake your ISR and task code so that only one request to the task is ever outstanding. This requires a simple (volatile) variable. eg in the isr if (!kicked_task) { kicked_task = 1; semGive(...) ; } and in the task: semTake(...) kicked_task = 0; /* process all outstanding requests */ This way the ISR only wakes the task when necessary.

The only reason why I alluded to 'a bug in the stack' is that the VxWorks problem report also mentioned something along those lines. Its fairly easy to figure out whether the driver is losing clusters. You modify the driver code so that instead of calling the function to submit the mblk chain to the stack you free it back to the pool. You then attach the driver to a frame source, sit back and wait. (You don't really need to wait that long because the addresses attached to the descriptors will form a regular pattern - if you start losing things the pattern will be disturbed.) If the stack had NULL buffer pointers, something the original code did occasionally due to a bug, then they can be seen by dumping out the descriptor ring. This doesn't mean that the driver is bug free, but rather that the code has been carefully searched for the more obvious bugs. Its also been tweaked to try to determine whether it fails due to losing sent frame buffers or whether its sensitive to one type of traffic or another. (Since its failure is irregular this suggests that its either an race condition or its picking up an unwanted broadcast packet that's doing it in.) Life is soooooo much easier when you can refer to the source...... --------------------------- Newsgroups: comp.os.vxworks Subject: Re: Who tell me more detail information about REG_SET?

Any ideas, pointers? I did not buy vxWorks source code, and I > can't modify it. Well, tNetTask is just a thread that listens on a message queue. A message is sent to it with a function pointer and arguments in it. See the header file definition of netJobAdd. You could replace tNetTask yourself without even seeing the source to it. The tNetTask is used for receive, but not for transmit. If you only need priority queuing on transmit, you needn't do anything with it. You can also change the Q that the netJob uses to be priority instead of fifo queuing, and use HI to put stuff on the front of the Q. You can replace the stack yourself without changing the vxworks source code by removing their objects and replacing them with the equivalent functionality from e.g. bsd4.4 etc. There are some papers available on making the BSD 4.4 stack priority aware. Its fairly involved. A search on altavista should yield more details. --------------------------- Newsgroups: comp.os.vxworks Subject: Re: HELP!

The MIPS R3000 has interlocks. Other than the fact the optimisation is a little suspect this should be harmless. The compiler does not handle hazards (involving the coprocessor 0 etc). Those have to be hand-coded. If you want that code emitted differently, I'm sure playing with the optimisation options upwards will get rid of it. --------------------------- End of New-News digest ********************** From vxwexplo-errs@csg.lbl.gov Thu Nov 9 01:53:13 2000 From: "sinnl" Date: Mon Nov 13 01:46:37 PST 2000 Subject: Response from sinnl (sinnl@sd-star.com) The person at this email address Larry Sinn, no longer works at Spectral Dynamics.

It all depends on what they do, and what their timing requirements are. Unless your system is very soft real time (i.e. you don't actually care when things run), then you can never design a system with multiple tasks without taking some notice of the priorities and timing relationships between the tasks. Now, the more tasks you add, the more complex that can become. Some questions to think about: 1) How are you going to assign priorities for all of your tasks? Remember, VxWorks is not a GPOS, it is an RTOS. With all your tasks at the same priority, there is potential for some of them to be starved, while others hog the CPU. Round-robin will help here, but that makes it even harder to predict what is going to happen. 2) Does your application really partition into 200 threads of execution? 3) How "hard" are your system's timing requirements? If there are multiple events with hard timing requirements, how will they be impacted by (a) each other and (b) all these other tasks (perhaps because a lower priority task is sharing a resource they need sometimes...). Well, there's some stuff to think about. The OS is capable of supporting 200 tasks (in fact, a lot more). The potential problems are in you hardware (CPU performance and memory requirements), and your application itself.

Message-ID: <8uol3q$knn$1@nnrp1.deja.com> References: <8ugn5q$o87$1@nnrp1.deja.com> Hi, changing a block device once mounted with the dosFs library is not that easy (the design of the VxWorks block device interface seems to purposely deny this feature..) but possible ! Here comes a two-part answer. For general, we have a library of our own to completely unmount a block device, re-partition a disk and then mount/format the new disk configuration without reboot. The necessary steps are disk synchronizing (e.g. using dosFsVolUnmout()) and deleting block devices (using iosDevFind/iosDevDelete). You might keep some pointers to the device headers (modifying usrAta.c, resp. usrAtaConfig()), this helps a lot. All this experience applies to both ATA and SCSI disks. As I understand your problem, the system fault occurs after changing the hard disk itself. From my experience with the SCSI stack, the scsiPhysDevCreate() function establishes a description of the disk parameter (that is the SCSI_PHYS_DEV * you get returned). However the pointer is stored in an array for later user. Any subsequent time, scsiPhysDevCreate() first tries to resolve a request by scsiPhysDevIdGet(). So your new hard disk will never be accessed and internal data not updated. A timely call to scsiPhysDevDelete() might solve your problem, then all(?) internal data structures associated with the physical device are freed.

Message-ID: <8upd0v$9bh$1@nnrp1.deja.com> References: <8uesf9$945$1@nnrp1.deja.com> Below is one method to do this. As a note I'm using a TME 5811 platform as my target. This is basically a Pentium based PC platform. 1) Modify BIOS settings to see the CompactFlash as an IDE drive. Apply power to the TME board and hit the delete key to get to the BIOS Setup Utility. Select the IDE HDD Auto Detection, and with the CompactFlash connected to the Primary IDE connector, the BIOS should auto detect the CompactFlash and configure it properly. With the CompactFlash connected to the primary IDE it will be boot device IDE-0. 2) Boot DOS from a floppy disk. 3) At the DOS prompt, run WindRiver's VXSYS.COM utility to write VxWorks bootstrap code onto the CompactFlash. To do this copy vxsys.com from the Tornado 2 directory \host\x86-win32\bin\vxsys.com and copy it to a floppy disk. Then with DOS booted on the target insert this disk and run: VXSYS C: A warning will appear about performing this on a hard drive, just ignore it. 4) Copy your BOOTROM.SYS to the root directory of the CompactFlash. BOOTROM.sys is created within Tornado 2 and placed on a floppy disk with the command bootrom_uncmp (see previous section for details). At this point the CompactFlash is ready to boot the BOOTROM.SYS and can then load the VxWorks system image from the host if that is what you wish to do If you are going to load VxWorks from a host you can change the BIOS settings To boot first from the IDE drive instead of the floppy (to save some boot time), hit the Delete key as the system is booting to modify the BIOS settings. Note that the CompactFlash is called a IDE device in the BIOS.

I think that the steps may pretty much be the same. The steps to the extension of the MIB agent should be as follows:- 1. Write your mib file say ex.mib 2. Compile it using the mibcompiler $mibcomp -stub -start (name of the module identity in your mib file) -o ex.c (list of mibs on which ex.mib depends) ex.mib Before doing this make sure that you set your MIBCOMP environment variable to point to the MIB search path where all your standard MIBs are located (i.e set MIBCOMP = -l MIB-search-path) Once the ex.c file is created copy it to the directory ...\snark\vxworks\agent and modify it as per your needs. 3. Edit the file makefile.cfg under ..\snark\vxworks\agent a) add ex to SNMP_OBJS2 i.e $#equate(SNMP_OBJS2 $#objs(snmpsys mib snmptcp snmpudp saiolib ex)) b) add ex.mib to MIBSRC i.e 4. Run makmak in the $SNMP directory specifying wind.cfg 5. Type make all 6. You can see if you are able to get/set variables by using utilities like getif/snmputil. Hope this helps, By the way I have a question, if you follow all the steps for the initial compilation, did it compile at one shot for you. I had lots of compilation errors during the initial compilation and had to change the code in the source file at some places to get it running (of course I am using it for snmpv2 and not snmpv3) Regards, Piyush In article <8u9qai$3fp$1@nnrp1.deja.com>, Doug Dyer wrote: > > > I've actually built the beast, including v3 support. > You will have to build it outside of Tornado 2.0, and > then refer to the library as an EXTRA_MODULE within Tornado. > > Part 1 > ===================== > Ill assume that $SNMP is the installation directoy of the > epilogue stuff.

However, when I use "ipAddrAdd" (ex. ipAddrAdd "nt0", "90.0.0.2") to add another IP address, that new address doesn't seem usable. For instance, the second address doesn't respond to pings from the same vxSim or from the DOS prompt, although it does show up when I do an "ifShow."

If you were willing to use a different compiler, then you should take a look at the Green Hills compilers. Green Hills compilers generate code into separate files related to each object file called .dbo files. When the MULTI debugger is brought up on the executable, it only pulls in debug information related to the functions you are debugging. This allows MULTI to come up quickly as if you were debugging a 1MB file. MULTI also has integration with ObjectTime (RoseRT today). This allows you to walk through your state diagram in RoseRT with RoseRT controlling the vxWorks target application through MULTI.

Message-ID: <8uqqej$e4q$1@nnrp1.deja.com> Hi there, I'm currently working on a signals demo, to see if it would fit our needs. The problem I have is : every time I raise my signal, the processor time is shared between the signal raising task and INT36. Yet, I don't raise any interrupt during the process (not consciously at least). My demo program is as follows : 2 tasks : - - background task (bg) : loops forever, doing nothing else - - signalling task (sg): loops and, every 500000 values, prints the counter value, and sends the signal (kill) I'm working with Round Robin Scheduling, and both tasks have the same priority. Boths tasks alternate regularly, until I send the signal. Then sig alternates with INT36. The Signal handler doesn't seem to be called. (For ASCII art fans :) INT 36 - - - bg ----- ----- ----- ----- sig ----- ----- -| - - ----- If anyone has an idea on how to explain the INT36 appearing here, that would really be helpful.

If you want to remember this, you have to program it yourself. I do not agree that it is bad practice or common practice to close a = socket=20 in a task that did not open it. I use it frequently in cases where a=20 "listener" task waits for connection requests. When a connection is = made,=20 a new task is created to handle the communication with the client. This=20 "handler" task receives full responsibility for the socket and the=20 "listener" task has no longer anything to do with the socket.

The client will be on host(solaris) machine which will call standard system calls ( like open(),close(),read(),ioctl() etc) through RPC calls. The server side contains only the corresponding functions which actually call the standard system calls on the target machine( vxworks) protocol stack. We have taken SUN RPC's as the standard because it is supported by both vxworks and psos operating systems. We could compile for the client's side on a compiler for solaris but we couldn't compile for the server's side (which runs on host) on vxworks compiler on NT machine. remember that server() side contains only the procedures. Our main requirnments are. 1. target machine ( containing the protocol stack) should be on VxWorks O.S . Server will run on this machine and server contains only the RPC procedures[nothing like main()] which call the standard systems calls like open(), close() etc., - w.r. t above we need the information on compiler ( whether to use cross compiler on solaris for vxworks O.S or something else) and compilation procedures also. 2. host machine ( which runs daemons / applications) should be on solaris O.S. client will run on this machine and client calls the RPC procudures which are coded at the server side. - we could compile for the client side on solaris compiler available on solaris machine.

The ARM certainly comes with them disabled. I recall that the reason has to do with being able to write to FLASH - which requires uncached accesses. However this can be solved in other ways - eg mapping the area two addresses, or disabling the cache during write operations. The performance of my ARM system with the caches disabled is absolutely abysmal. I enable the I and D caches for the ROM in order to get the system boot time to a respectable figure (about 3 seconds). This does require a certain amount of care in the BSP to ensure that the cache and TLBs never contain incorrect data, and that the D-cache is flushed of new code. (My cache/MMU/TLB handling is a lot safer now I now longer use the network boot 'ROM' code nor the soft restart. I had terrible problems because the cpu would be using page tables from random areas of DRAM.)

The information it returns is necessarily out of date if any other task is able to perform a put/get on the queue.

The vxWorks code seems to contain loads of checks that should never fail, and no reference counts on items so it is possible to tell when something can be deleted. > > It was my belief that the O/S calls, such as msgQSend should be completely > safe from unexpected task suspend or delete operations.

The client will be on host(solaris) machine which will call standard system calls ( like open(),close(),read(),ioctl() etc) through RPC calls. The server side contains only the corresponding functions which actually call the standard system calls on the target machine( vxworks) protocol stack. We have taken SUN RPC's as the standard because it is supported by both vxworks and psos operating systems. We could compile for the client's side on a compiler for solaris but we couldn't compile for the server's side (which runs on host) on vxworks compiler on NT machine. remember that server() side contains only the procedures. Our main requirnments are. 1. target machine ( containing the protocol stack) should be on VxWorks O.S . Server will run on this machine and server contains only the RPC procedures[nothing like main()] which call the standard systems calls like open(), close() etc., - w.r. t above we need the information on compiler ( whether to use cross compiler on solaris for vxworks O.S or something else) and compilation procedures also. 2. host machine ( which runs daemons / applications) should be on solaris O.S. client will run on this machine and client calls the RPC procudures which are coded at the server side. - we could compile for the client side on solaris compiler available on solaris machine. If any one can provide the information at the earliest, it will be very useful.

I am using ping from within an application to determine if a remote system is available. If I call the ping routine from within the application, it returns saying that it could not reach the system. The Code I am using is as follows : ping ("196.11.193.182, 1, PING_OPT_SILENT); However if I use the Ping routine from the shell, it reports that the remote system is available, which is the correct response.

How many do ya want ? Optimizer bugs are well known to exist in gcc 2.7.2 (and variants). You didn't mention what CPU architecture you're using, but we've had nightmares with PPc and gcc 2.7.2. It miscompiles very obscure bits of code that can't be easily detected - there doesn't seem to be any pattern to what makes it go wrong. For your entertainment I have copied a bunch of SPRs from WRS' support site. None of them have been fixed. Workarounds include such gems as 'treat all memory references as volatile', 'dont use the optimizer', and my particular favourite, "We suggest, as a workaround, that you use asm() directives to generate the code that you want, or code the routines in assembler." IOW, the compiler doesn't work so hand compile your code. D'oh! Now why didn't I think of that? I raised the problem with WRS support a while ago. Their answer: "Well, you're stuffed then, aren't you. No, we aren't going to fix it." (I am paraphrasing here, but I feel I have accurately conveyed the essence of WRS' support service). I'm attempting to solve the problem myself by building the latest (2.95.2) GNU release of the compiler, but there are particular problems with doing so for my target platform (Ppc), since GNU have changed the implementation of the EABI calling conventions and (in particular) varargs handling between these two versions, which has the consequence that the new code I compile is not quite compatible with the VxWorks libraries. If we had a source code license for the entire OS we could presumably rebuild it ourselves with the new compiler and it should work, but the cost of WRS source code licences rules out that consideration as far as our management is concerned. We also had a quick try-out of the DIAB compiler that WRS sell, and found that it also appeared to have optimization bugs, although we didn't investigate in depth. When you do find an optimization bug in your compiled code, it can usually be fixed by breaking down the expression that is miscalculated into simpler parts and using temporary variables for any repeated parts - in short, do the common subexpression elimination manually.

RESOLUTION: The GNU 2.7 compiler optimization scheme does not account for order dependency. When the compiler encounters the while loop, it assigns the counter variable "i" to a value "9" versus "0". For instance, the following is a dump of the while loop: while(i<10) 00000032 <_test+12> moveq #9,%d2 <- COUNTER SET TO 9 00000034 <_test+14> lea 000000b0 <_statics+24>,%a0 { global->object_table[i].next = last; 0000003a <_test+1a> movel %a1,%a0@ last = & global->object_table [ i ]; 0000003c <_test+1c> moveal %a0,%a1 i++; 0000003e <_test+1e> lea %a1@(-4),%a0 } 00000042 <_test+22> dbf %d2,0000003a <_test+1a> 00000046 <_test+26> clrw %d2 00000048 <_test+28> subql #1,%d2 0000004a <_test+2a> bccs 0000003a <_test+1a> global->free_list = last; 0000004c <_test+2c> moveal 000000b8 <_statics+2c>,%a0 00000052 <_test+32> moveq #36,%d1 00000054 <_test+34> addil #140,%d1 0000005a <_test+3a> movel %d1,%a0@(40) This is great since decrementing a counter takes less work then incrementing and comparing values. However, the compiler doesn't account for code that depends upon a specific order. Thus, the problem. The testcase relies upon the counter starting from zero and incrementing to 9. Since, the compiler assigns the array indexes in the wrong order, the link list gets created backwards. This is a bug. The workaround is to either declare the pointers as volatile or compile the source file with the - -fvolatile flag.

SYSTEM:DESCRIPTION:Need to access the VMECHIP2 registers with maximal efficiency in the trigger crate monoboards. The GNU C compiler optimizes to incorrect code by deciding to do 16 bit transfers rather than 32. The VMECHIP2 registers don't support 16 bit transfers. In the past, this was adjusted by defining the transfer to be "volatile" and accepting the inefficiency shown in the assembly code fragment below which is generated by the C compiler. (There is a "#include " statement at the head of the file.)===Without volatile designator============ C: *(unsigned int *)VMECHIP2_DMACR1 &= ~DMACR1_DWB; asm: andw #57343,-786382 Note:If DMACR1_DWB is not complemented, and "andl" is generated. Also applying an "unsigned int" cast to DMACR1_DWB doesn't help. ===With volatile designator=============== C: *(volatile unsigned int *)VMECHIP2_DMACR1 &= ~DMACR1_DWB; asm: movel #-786384,a0asm: movel a0@,d0asm: andw #57343,d0 asm: movel d0,a0@ As you can see, the transfer to -786382 (0xfff40032) is "word" length in the first instance, but "long" length in the second. However, the second instance moves the data around a lot.SYMPTOM(S): RESOLUTION: We do not believe the behavior of the compiler can be called "incorrect" or even "non-ANSI" in this case. You maintain that the constant DMACR1_DWB (which must be defined as 0x2000, looking at the code) has not been treated as an unsigned long, as the ANSI standard requires. But really it has: ~0x2000 == 0xFFFFDFFF. In regards to this mask, the compiler has generated: andw #0xDFFF, address What has happened is an optimization. The full mask would be 0xFFFFDFFF. But, anding with one results in the original number. Since the upper 16 bits of the mask are all one, the compiler has decided that there is no point in performing the AND on the upper 16 bits. So, we see that the compiler is, in fact, treating the mask as unsigned long. If it were treating it as a short, it would have to AND with 0x0000DFFF, so that the upper 16 bits of the target would be cleared. In the way that the compiler does it, the upper 16 bits are left alone, which is what should happen if ~0x2000 is treated as a long. Now, you turn on volatile, and are disappointed to see that extra instruc- tions get emitted. What you really want is for: andl #0xFFFFDFFF, addressto be emitted. We suggest, as a workaround, that you use asm() directives to generate the code that you want, or code the routines in assembler (so that they can, hopefully, use the #defines in the include file.) The optimizer (when the volatile keyword is used) isn't generating the fastest possible code, we admit, but we think this could be a request for enhancement rather than a bug as you suggested. The compiler (without volatile) is trying to generate the fastest code it can. That accounts for why the code generation depends on the value of the mask. For small positive masks, sometimes moveq's are used before the and. When volatile is on, the compiler doesn't try as hard to optimize, and that's a bit of a disappointment. But we think that if performance plus machine register access is needed, that assembly language is a legitimate workaround.SEE ALSO:GROUP: compilers - ---------------------------------------------------------------------------- - -- They laughed at Galileo.

The ARM certainly comes with them disabled. I recall that the reason has to do with being able to write to FLASH - which requires uncached accesses. However this can be solved in other ways - eg mapping the area two addresses, or disabling the cache during write operations. The performance of my ARM system with the caches disabled is absolutely abysmal. I enable the I and D caches for the ROM in order to get the system boot time to a respectable figure (about 3 seconds). This does require a certain amount of care in the BSP to ensure that the cache and TLBs never contain incorrect data, and that the D-cache is flushed of new code. (My cache/MMU/TLB handling is a lot safer now I now longer use the network boot 'ROM' code nor the soft restart.

Date: Tue, 14 Nov 2000 14:51:45 -0000 From: "David Anderson @ Data Track" Organization: Lawrence Berkeley National Laboratory Message-ID: <8urksb$k91$1@overload.lbl.gov> vxWorks : 5.3.1 Tornado : 1.0.1 Processor: Coldfire Hello all, Is there a known bug with task interactions in the following scenario: task1 [ higher priority] task 2 [ lower priority ] ............................................................. start of msgQSend( a message ) !! task 1 pre-emption. !! task suspend task 2...................................[suspended in msgQSend] close task2 i/o handles task delete task 2......................................[deleted while in msgQSend] It appears possible for task2 to suspend in such a way that msgQNumMsgs() does NOT return the correct value in another task ( task3 ) which receives from the Q. I believe task 2 takes a vxWorks semaphore and is then deleted before the semaphore is released ( locking up access to the Q ). The msgQSend is always being executed by task2 as it is called with WAIT_FOREVER with the Q normally full.(This causes task 2 to yield to task3). It was my belief that the O/S calls, such as msgQSend should be completely safe from unexpected task suspend or delete operations. Placing taskSafe/taskUnsafe calls around the msgQSend cures the problem. NOTE: I agree it is not good practice ;-) and has been replaced by another method.

My test will run on all clients at the same time and they all will open the same file at the same time on a server, which runs Solaris, through the Ethernet. The problem with that is that when more than 12 clients try then the network get jammed and my test will fail. How will I approach this problem? Can I set a lock after the firt client opens the file successfully so others can not access it until it is done with it and release it? How would ne the best approach ? How can I resolve the network congestion? Appreciate any help on this.

Clearly pathnames can be considerably longer than this in practice, and the small value will (as was the case of code I was porting today) trip up code which doesn't sanity check the size of the buffer it is copying into (assuming that it is always long enough).

If your sysadmin has dedicated an address and name for the target in the local DNS, then you should talk to him/her. If you are standalone (i.e. your own local intranet, pick one of the experimental IP addresses which are defined in the latest RFCs for IP addressses). As far as how to hook up your serial cable to your P.C., most of the time the bootprom is setup to use serial port #1, but read the information for your BSP if you have access. Anyway, once you know which port the bootprom will be communicating out of, I believe a Null modem cable to your local Windows machine COM 1 or COM 2 with Hyperterminal will work. Or if your host is a flavor of Unix, there are several serial communication programs to set up a connection. 9600 baud , 8 data, 1 stop no parity I believe is the usual serial setup. hari wrote: > hi joe > thank you for your reply. but still i have one doubt, please help me > out, it will be a great help to me > 1. how can i find out the the target name/ip address of target > 2. should there be a cable connection between host and target and if yes, > please tell between what ports there should be a connection, i am using > powerPc target. > once again thank you joe > bye > hari > > Joe Durusau wrote: > > > It's in the user's guide.

When you include the node in your own structure you can add this to the linked list. For example: typedef struct lstExampleStruct { NODE node; char data[20]; } lstExample; LIST exampleList; lstExample exampleData; .... lstAdd(&exampleList, &exampleData.node); ....

Fixed in my ARM version by patching a jump to the following over the first instruction of ping. .global _fix_ping _fix_ping: cmp r1,#0 moveq r1,#5 mov r12,r13 b _ping+4 Another solution for the target shell is to 'fix' the symbol table so that 'ping' references a different function. Maybe you could define 'ping' (rather then '_ping') in an asm file. (I haven't checked on the order in which vxworks target shell checks for symbols.)

Well, since the OS libs are precompiled with the flag on, they'll stay working no matter what. The only danger is when you have constructs in your own code such as the one in TSR# 48742 in my last post. In those circumstances you have to choose: either use -f volatile, or use - -O0. Which one of those is a worse performance hit is a YMMV kind of thing. DaveK - -- They laughed at Galileo. They laughed at Copernicus. They laughed at Columbus.

Message-ID: <8uu9pd$8ne$1@nnrp1.deja.com> Hello everyone- I was wondering if any of you know if the usrStartupScript is re-entrant? We have a boot script which downloads a program to our board and kicks it off with a taskSpawn(). This program then calls usrStartupScript() directly and provides it the name of a second script which downloads more programs and kicks them off. Is this "cricket"? Should usrStartupScript even be called directly? I notice it's not in the VxWorks 5.3.1 reference manual. Does the kernel/VxWorks expect this function to only be called once, and so a direct invocation for a 2nd time could screw something up? Any insight any of you have would be most welcome.

As far as I remember you should use sysIntEnablePIC() function (in sysLib.h). I used intEnable() and intConnect() function also to make a USB driver work (this is also a PCI device). I never used pciIntConnect. If you use the above function you also have to add a special offset together with your interrupt number which I don't remember anymore.

TIME_WAIT is the state a TCP endpoint must enter when it initiates the close of a connection. It is there as part of TCP's correctness algorithms to make sure that a new connection with the same "name" does not mistakenly accept segments from an old connection and hence incur silent data corruption. The stack is behaving properly (IMO) when it pauses after 45 connections if it can only track ~45 TCP states at one time. The implication is that you are trying to churn through TCP connections at a rate faster than (maxtrackedstate/timewaitinterval). You might try doing more work in each individual TCP connection and thus reduce the connection curn rate - perhaps persistent connections would be in order. Another option would be to try an increase the maximum number of trackable states. Another would be to try to get the other side to initiate the connection close. You _could_ consider dropping the TIME_WAIT interval, but I would not suggest a value less than 60 seconds. I would ceratinly suggest that yo do _not_ do anything like try to induce abortive closes to bypass TIME_WAIT. hth, rick jones - -- rachel marina jones, 09/24 0317, 7lbs, 7oz, 20" these opinions are mine, all mine; HP might not want them anyway... :) feel free to email, OR post, but please do NOT do BOTH... my email address is raj in the cup.hp.com domain... --------------------------- Newsgroups: comp.os.vxworks Subject: Socket memory leak/defrag Date: Wed, 15 Nov 2000 14:43:43 -0600 From: "Chris Smith" Organization: Posted via Supernews, http://www.supernews.com Message-ID: I am seeing an odd 32 byte memory leak each time my socket based server receives a connection from a client. I am running a server on a ppc running vxworks 5.4. When this server receives a connection my software allocates a 32 byte structure and a 400000 byte input q. A memShow after this connection is establised shows available free memory has decreased by 400080 bytes (any ideas where the extra 48 came from). When a disconnect is received my software deallocates the 32 byte structure and then the 400000 byte q. A memShow at this point shows that all but 32 bytes have been freed. ie 32 bytes have been dumped on the floor. Each connection that is made to the server results in 32 bytes dropped from the memory pool. If a connection is made then disconnected and another connection is made then disconnected 64 bytes have disappeared. This scenario is important because it shows whatever this 32 bytes is allocated for it is not being reused (as implied in a wrs tech solution). This 32 bytes is not freed after a certain amount of time (at least a day) either. The net result is the memory space gets butchered even faster than even the first fit memory scheme can accout for. Incidentally the mbuf structure used by the tcp stack is 32 bytes wide (but mbufs should not be allocated out of the general memory anyway). Has anyone else seen this behavior? Can anyone offer an explanation? Our software is fairly simplistic so I do not think it is in our code (but if noone confirms this behavior it must be). I have never noticed this behavior (since I have never had the need to make dynamic connections before) but it appears to be in every system we are currently developing. As a side question: Is there any code floating around to manually defragment memory under vxworks? (Open source preferably) I have sent the fixes to replace the memory allocation scheme but never anything to manually defragment it. I do not want the possible performance hit involved in a better allocation scheme but I would not mind taking a performance hit once every few hours to defrag.

It can be found at the following URL: http://www.netrino.com/Connecting/1999-10/ This article was published in the October 1999 issue of Embedded Systems Programming. It is an overview of the IrDA-Data and Bluetooth protocols, with attempts to compare them on several features. Some of the Bluetooth info is now (after more than a year) a bit outdated, but the generalities are still useful and there are links within the article to more up-to-date sources of info on both protocols. The Netrino Consultants Network encourages its partners and associates to share their technical expertise by writing magazine articles and books and by speaking at industry conferences.

The VxWorks libraries are compiled in big-endian mode, so your code also has to run in big-endian mode. The only way around this is to recompile the kernel in little-endian mode, but I am afraid WRS will not provide you with the sources, unless you pay a huge amount of money :-) >I am developing for a PPC-based embedded system that must communicate >over a PCI bus with an Intel x86 processor running Windows NT.

Each piece of memory allocated has an 8 byte overhead - the two words before the address you are given are the length (in 2 byte units) and pointer to the previous item. The bottom bit of the length is the allocated/free bit. So you should have allocated 400000+8+32+8=400048 - so someone else allocated 80-48-8=24 bytes. From 'memShow 1' before and after the test you should be able to find the piece of memory that is no longer on the free list. This is VERY likely to be the lost memory block. Especially if its contents don't change when you repeat the test. Given the contents you need to guess what it was used for! It that doesn't show anything, try a bit of hacking! Write a little routine to replace 'malloc' (ie calls memPartAlloc( memSysPartition, size ), place a jump to it over the first instruction of malloc. Add code to trace calls requesting 24 bytes including the callers address (extract from the stack frame probably *(&arg +/- n) will do it, don't know the ppc abi - so don't know exact values.). Find the unfreed item in the allocation trace and you know where the memory was allocated. > Is there any code floating around to manually defragment memory under > vxworks? (Open source preferably) I have sent the fixes to replace the > memory allocation scheme but never anything to manually defragment it. Defragmentation is essentially impossible! Schemes that assume that anything that looks a bit like a memory address must be one have been used for garbage collection, but defrag would require changing random numbers hoping they were pointers to heap memory rather than, say, an instruction! I use a reverse engineered memPartAlloc that does a best-fit. This has to scan the entire free list for each request. However the free list is so much shorter than with the vxWorks 'fragment the heap as much as physically possible' algorithm that this is probably a performance gain. The code doesn't affect the heap structure - so memShow still works.

We have a boot script which downloads a program to our board and kicks it off with a taskSpawn(). This program then calls usrStartupScript() directly and provides it the name of a second script which downloads more programs and kicks them off. Is this "cricket"? Should usrStartupScript even be called directly? I notice it's not in the VxWorks 5.3.1 reference manual. Does the kernel/VxWorks expect this function to only be called once, and so a direct invocation for a 2nd time could screw something up? Any insight any of you have would be most welcome.

Each piece of memory allocated has an 8 byte overhead - the two words before the address you are given are the length (in 2 byte units) and pointer to the previous item. The bottom bit of the length is the allocated/free bit. So you should have allocated 400000+8+32+8=400048 - so someone else allocated 80-48-8=24 bytes. From 'memShow 1' before and after the test you should be able to find the piece of memory that is no longer on the free list. This is VERY likely to be the lost memory block. Especially if its contents don't change when you repeat the test. Given the contents you need to guess what it was used for! It that doesn't show anything, try a bit of hacking! Write a little routine to replace 'malloc' (ie calls memPartAlloc( memSysPartition, size ), place a jump to it over the first instruction of malloc. Add code to trace calls requesting 24 bytes including the callers address (extract from the stack frame probably *(&arg +/- n) will do it, don't know the ppc abi - so don't know exact values.). Find the unfreed item in the allocation trace and you know where the memory was allocated. > Is there any code floating around to manually defragment memory under > vxworks? (Open source preferably) I have sent the fixes to replace the > memory allocation scheme but never anything to manually defragment it. Defragmentation is essentially impossible! Schemes that assume that anything that looks a bit like a memory address must be one have been used for garbage collection, but defrag would require changing random numbers hoping they were pointers to heap memory rather than, say, an instruction! I use a reverse engineered memPartAlloc that does a best-fit. This has to scan the entire free list for each request. However the free list is so much shorter than with the vxWorks 'fragment the heap as much as physically possible' algorithm that this is probably a performance gain. The code doesn't affect the heap structure - so memShow still works.

It's best to not run the startup script to download code that needs debugging... On PPC's the target shell loader and the WindShell (Tornado) loader, load code on opposite ends of memory!!! If you have over 32 meg, then this will cause great confusion, if you try and mix the loads. Run the startup script from the T2 target server console after the kernel boots. Even if you have the symbol tables sync'd, the source code debugging and operation will be difficult if the "core" filenames and object modules are not accessed from the same path names. There are places to hardwire these paths, but they are a hassle to maintain... Use the "@moduleShow" and the "moduleShow" show commands from the host shell to see if and when you have everything synchronized. viveks wrote: > Hi > I have one problem in how to configure target server to debugger. > > Actually I in my setup I have two machines one solaris and one Intel. > My target is PPC860.

I thought this was supposed to be fixed in 5.4 but I guess not. Your observation about the 8 byte overhead for each memory allocation is correct for allocations in sizes that are multiples of 8 bytes, but for odd values like 100 it is not. 100 is rounded to 104 then 112 bytes is actually allocated (see below) Of course that had no impact on my problem since 400000 and 32 are both multiples of 8. I am still not sure where the other bytes came from but they are gone now. Only the 400048 are allocated. I actually thought it would not be so hard to defragment memory by searching the "free list" that memShow uses and combine adjacent free blocks -- remove one enry and increase the size of the other. (if you look at a badly fragmented memShow there are lots of adjacent free blocks they are just never conjealed if they are not deallocated from the top of the heap down) This sounds like a simple enough solution I am surprised there are no hacks of this variety out there.

Another issue is linking Diab-compiled code with GNU-compiled code, specifically BSPs and drivers. The local Wind River office says no problem.

Singlestep for C++ works much better if it has DWARF debugging information. Unfortunately the GNU C++ compiler doesn't generate it. I've used Singlestep (for PPC) with both GNU and Diab. In my opinion it works much better with Diab. I'm currently using it with GNU C++ and can get by, but things like line numbers and inline functions are a pain. If I had it to do over again, I might have gone the Diab route. > > Another issue is linking Diab-compiled code with GNU-compiled code, > specifically BSPs and drivers.

But debugging of that code is dependent on the information contained in either the .debug or .stab section, and that lies outside the ABI. When mixing C++ from the two vendors, you may also run across different preferences in how runtime initialization of static objects is handled. GNU prefers a munch strategy, where Diab can generate .init/.fini code. - -- - -------------------------------------------------------------------------------- Lee Douglas Gibbons ldgibbons@avaya.com --------------------------- Newsgroups: comp.os.vxworks Subject: Re: Debugging multiple tasks Date: Thu, 16 Nov 2000 16:04:27 -0800 From: Robert Blumberg Organization: Posted via Supernews, http://www.supernews.com Message-ID: <3A14760B.5C00EF2F@fake.com> References: <3a145dc3.22450422@news.netis.com> > it would be A Big Help if I could set breakpoints in both If I understand correctly, you could use "Debug/Toggle Global Breakpoint" to do this.

Are they in the same place as they were on the Solaris machine? Check if the filenames in the object files are relative or absolute. You can change the makefile on the solaris to generate a "relative" version by changing the PRJ_DIR macro to the current directory by using the following line: PRJ_DIR = . Hope this helps.

The vxWorks manual says that 18 bytes are allocated for each call - so the routine is working to spec :-) Maybe the manual should say that the returned string is allocated from the heap and free() should be called to avoid a memory leak. This is safer than the inet_ntoa_b() call as it doesn't require the caller know the length of the required buffer. > I actually thought it would not be so hard to defragment memory by searching > the "free list" that memShow uses and combine adjacent free blocks -- remove > one enry and increase the size of the other memPartFree() SHOULD be doing that anyway! The allocated size gives it the address of the next item, and the pointer the start of the previous. If the next item is free it is unlinked from the free list and its size added to the item being freed. If the previous item is free its length is changed. If you are getting adjacent free items on the free list someting nasty is happeneing. I'd check that you don't try calling malloc() or free() from an ISR.

From all the infinity range on numbers, they >took the worst...:). Just a thing of user-friendliness, that's all. Well, I imagine the reason that they didn't make zero mean 'send three packets' is because that would be redundant: if you want 3 packets, use '3' for the second arg. instead of zero. In fact, infinity is the only 'special case' here, and so has the best claim to be represented by a special case in the args. You could argue that WRS should have made 0 mean 3 packets and negative numbers should mean try forever, but then someone else would come along and say 'No, 0 should mean send 4 packets'... It's just an arbitrary convention, it can only be done one way and that's the way it's done. After all, when you're typing commands manually from the shell, you can use Ctrl-C to interrupt it, and when you're calling it as a function from your own program you won't omit any of the arguments. >took the worst...:).

It went and started pinging the target and I knew the machine was up and running. When I got bored I pressed Ctrl-C.

They are running external executable files and passing command line parameters to them, whereas you (and VxWroks) are calling a C function from within a running program. The trouble is that the nature of the VxWorks shell makes a function call *look* *like* a program invocation, but they aren't the same thing, and so there's no innate reason why they ought to behave the same.

The GUI debugger buttons are duplicated for each task to which you attach the debugger. (seems like a simple approach... Not clear why WRS can't provide the same capability!!!)

The only way to get a duplicate set of debugger GUI buttons with Tornado is to open another instance of Tornado.

The vxWorks manual says that 18 bytes are allocated for each call - so the routine is working to spec :-) Maybe the manual should say that the returned string is allocated from the heap and free() should be called to avoid a memory leak. This is safer than the inet_ntoa_b() call as it doesn't require the caller know the length of the required buffer. > I actually thought it would not be so hard to defragment memory by searching > the "free list" that memShow uses and combine adjacent free blocks -- remove > one enry and increase the size of the other memPartFree() SHOULD be doing that anyway! The allocated size gives it the address of the next item, and the pointer the start of the previous. If the next item is free it is unlinked from the free list and its size added to the item being freed. If the previous item is free its length is changed. If you are getting adjacent free items on the free list someting nasty is happeneing. I'd check that you don't try calling malloc() or free() from an ISR.

I have a TSR opened with WindRiver but they have not been able to help me with this as of yet. The following describes the procedure I have followed so far: 1. I created a user that is not root to perform the installation. 2. I logged in as that user. 3. I changed to the directory of the mounted cdrom and executed ./SETUP 4. The utility displayed the following: Tornado 2.0 Setup Copyright (c) 1999, Wind River Systems, Inc. All Rights Reserved 5. The cdrom is accessed by the machine and the program terminates with no further information. The Welcome dialog box does not appear. A .wind directory appears in my home directory but no other files appear in the system. The install script appears to want to install the files from the /usr/wind directory. I created the directory and granted all user access to write the the directory. Still no files appear there after the ./SETUP script is run. Does any one have any suggestions on what I may try to perform the installation?

[Note: spelling may be wrong on the macro - I'm working from memory]. I believe that there is a tech note describing this on WindSurf - you should probably check WindSurf before posting questions here; it might get you an answer immediately, especially for "usage" questions as opposed to in-depth technical ones. (2) You can add the shell startup script execution feature (there is a macro for this that you should define in config.h for command line builds, or find it in the Tornado IDE and add it from there). Then, specify the name of a script that you want the shell to execute at start time. That location of that script will depend on the boot device and user information. Check the manuals for more info on this. HTH, John...

Indeed the documentation for (and many sample) END drivers does not handle transmit flow control properly. Often leading to lost clusters from one of the buffer pools. If you try to send datagrams faster than the network can accept data, the application should block in sendmsg() - or get an EAGAIN response on a non-blocking socket. (This is certainly DESIRABLE - even if not documented.) You can (probably) stop packets being lost by counting bytes through the interface yourself. If you allow 600kbytes/sec = 10kb/tick or 20 500 byte messages per tick you probably won't lose any data.

Tredyffrin Message-ID: <8v9eum$jqa$1@trsvr.tr.unisys.com> Using Vx/Works 5.3.1 and iq960rx BSP with Dec21x4xEnd ethernet, I'm having a lot of trouble getting my socket send() to work correctly after I set my socket fd to non-blocking mode. The symptom I'm seeing is duplicate data being transmitted across the socket in cases where I must retry a send() after a previous EWOULDBLOCK or EAGAIN error. (I used network monitor traces to help arrive at my conclusion.) Does anyone know of any bugs in this area? If so, I would GREATLY appreciate any suggestions for a workaround. My basic goal is simply to never block on a socket operation -- I don't really care what I must do to make it work. One of the things I have tried to do to overcome my problem with non-blocking mode is to use select() to tell me when the socket becomes "writable". Unfortunately, this can still result in the send() blocking because an fd apparently becomes "writable" when 1 byte can be written to it without blocking. I need some way to ask "can I write bytes to the socket now without blocking?"; select() just answers "can I write 1 byte to the socket now without blocking?". Vx/Works doesn't appear to implement the SO_SNDLOWAT (send low-water mark) socket option, which I believe could be used to modify the behavior of select(). FYI, I describe my algorithm below for handling non-blocking sockets. Set the socket non-blocking after opening it: int on = TRUE; ioctl (sock, FIONBIO, (int)&on); Issue each send() in a loop, which handles these error conditions: 1. send() returns -1 with an errno value of EWOULDBLOCK or EAGAIN -- I recover this case by simply sleeping and re-looping. (My finished version of code will probably do something more important than sleeping, but for testing that is sufficient.) I have observed executing this code in my testing. However, it seems like whenever I get into this code, there is extraneous send data that gets delivered over the socket. 2. send() returns -1 but the errno value is neither EWOULDBLOCK nor EAGAIN -- blow up with an error and close the socket. I have not observed this happening in my tests. 3. send() returns 0 -- blow up with an error and close the socket. I have not observed this happening in my tests. 4. send() returns a positive value -- increment the buffer pointer by the positive value returned, decrement the bytes-left-to-send value by this positive value, and re-loop. --------------------------- Newsgroups: comp.os.vxworks Subject: accessing I/O on PC from VxSim Date: Sun, 19 Nov 2000 19:26:01 -0500 From: "Brannen, Bill [CAR:1V79:EXCH]" Organization: Nortel Message-ID: <8v9r2q$j9n$1@bmerhc5e.ca.nortel.com> I'm trying to access the I/O address space (specifically the data, control, and status ports for the parallel port) directly from my VxWorks based software while running VxSim on my PC (NT).

Not sure about the specific question you asked, but the normal method of calling another startup script is to use the '<' shell redirection operator, which is probably better than calling some other function to do this, e.g. (nfsMount.st contains commands to mount stuff from an NFS server): < nfsMount.st cd "/home/target/1" ld Message-ID: <3A197FC4.DF2FAEC1@hotmail.com> Reply-To: kanigeri@hotmail.com hi i am working with pcc target and window-95 host.

Al did some more work on this since my reply, and it appears that there are major problems with getting VME bus errors properly reported due to the PowerPC architecture, and there may be no complete solution. You will find that no exception occurs on write if the relevent Universe master window has write posting enabled; exceptions on coupled writes may report the wrong instruction (and hence indicate the wrong routine or possibly even halt a different task); exceptions on read usually report the correct location for the exception, but this isn't guaranteed according to a strict interpretation of the PowerPC specs (because MCE is an imprecise exception), although in practice I don't think either Al or I have seen this happen. To find out about the occurrence of bus errors on write cycles you can set up the parallel interrupt capability of the Universe chip, but don't expect to be able to tell anything about which instruction, routine or possibly even which task caused the bus error to occur. You should be able to get the bus error address from the Universe registers though. > Another related question: Is it clear to you if I shuld use excConnect > or excVecSet if I want to catch the exeption? Look at your BSP, one of the sys*Probe() routines sets up the Universe chip and an exception vector to trap it - these are support routines for vxMemProbe(). I'm not sure about the specific answer to your question, but copying the BSP solution should work. - - Andrew - -- Every great idea appears crazy to start with. --------------------------- Newsgroups: comp.os.vxworks Subject: Re: Errno variable Date: Mon, 20 Nov 2000 14:17:25 -0600 From: Andrew Johnson Organization: APS, Argonne National Laboratory Message-ID: <3A1986D5.D6DB0D96@aps.anl.gov> References: <8vbnjf$he5$1@panther.uwo.ca> Harman Bassan wrote: > > I get an ERRNO variable 41 from the tNetTask.

Check the documentation for > the part that you're proposing to use. I agree that the PCI bridge should do most of the work. However, if using PCI devices or software designed for little-endian, you still must consider every data item individually for endian problems. Under VxWorks you must run the PPC in big-endian mode. Although the PPC supports little-endian in hardware, almost no software support is available for that mode. I asked WindRiver, and they do not support VxWorks on the PPC in little-endian. I was quite relieved by this answer, because it would have been an abomination. --------------------------- Newsgroups: comp.os.vxworks Subject: CPV3060 Board BSP Package Doesn't Work!

You have to GIVE IT ONE YOURSELF!!!!! The general procedure is to connect a serial terminal configured as 8N1 to the serial port 1 of the target, then turn the target off and back on. If the target works, you should see a message within a few seconds saying something like: press any key to stop autoboot and a countdown should start below the message. It the target doesn't get this far, you have a defective target, a defective terminal, or your connection to the target is bad. I have had experience with some vendors of PPC cards that won't boot unless you use the vendor's own VME chassis. :-( If you do see the message, press the spacebar or some other key. The next message should be vxworks boot: (Or something similar, I don't have a book here). At this point, several commands are available. ? should get a list of commands. c should get you into the routine that changes boot parameters. The idea is that the system will show you each boot parameter in turn, and give you an opp to change it. Sorry, I can't do you whole job from here, but the ip address is set in ip on enet or something similar. You will have to set up a bunch of things, and I've never tried to do this with a windoz host, but surely the details are in the manuals. If you get into this procedure, I think it will become clear. As to the basic question as to what ip address to use, if you just have the host and target hooked together in a private (2-host) network, pick anything you like. If you are hooking the target into your employer's net, check out an address from your network manager and use that. IU reiterate in case of lack of clarity: You SET the ip address, using whatever your local rules are, from the serial port of the target. Good luck, and please read the manuals(all 4 of them , all the way through) Speaking only for myself, Joe Durusau Ben wrote: > > hi > i am working with pcc target and window-95 host.

Hai,
We are working in Tornado 2.0.

We had created a workspace (namely "workspace12") and under that a project namely "project30" in which we have added all
our source and header files for compilation.

When we opened Tornado today, it showed some error whose description is as below:

"project 30 load files failed".

Due to this, the entire added files disappeared from the project and also the project30.wpj was not found in the corresponding
directory.

But the files are available in their physical locations.

Hence, now we have to add all the files again with the new project name.

Can we retrieve the files again with the same project and avoid the re-organisation of files?

Thanks and regards,
S.Parthasarathy.

Did you rebuild your boot disk with support for the network card? Are you using the network to download your new kernel? Just looking at the screen dump and your detail description of your steps, I am thinking that you defined your boot device as your ethernet device and it is not available (if this is not the case, maybe if you just print out your bootline would help get a start on this). When you get the boot shell and interrupt it, what are the available END devices when you enter [vxworks boot prompt:] help or h or whatever it is? Just some WAGs of mine.

We are working in Tornado 2.0.

We had created a workspace (namely "workspace12") and under that a project namely "project30" in which we have added all
our source and header files for compilation.

When we opened Tornado today, it showed some error whose description is as below:

"project 30 load files failed".

Due to this, the entire added files disappeared from the project and also the project30.wpj was not found in the corresponding
directory.

But the files are available in their physical locations.

Hence, now we have to add all the files again with the new project name.

Can we retrieve the files again with the same project and avoid the re-organisation of files?
