    DSP C6413 "Reuse Startup Code Space" in DSP/BIOS (5.32.03) configuration makes this GROUP appear in generated linker cmd file: GROUP { .sysinitgap {. += 0x8;} .sysinit: .IRAM$heap: { _IRAM_base = IRAM$B; _IRAM_length = IRAM$L; . += 0x2000; } } START(IRAM$B), SIZE(IRAM$L) >...

    Hello, It looks like this might be related to a known linker issue of Code Generation Tools version 6.1.x. I suggest trying CGT version 6.0.14 as this version of BIOS was built and validated on that version. From the Release Notes for BIOS 5.32.03: Validation Information This release was built...

    JohnAtANS Ouch! That's one of the main reasons chose a TI DSP for my latest project. I didn't technically need a DSP, but on past projects the GUI CSL made it really easy to get started and try various what-ifs. Is TI losing their edge, or their will to compete, or anything like that? I sincerely...

    Hi ciyoha, ciyoha Hi all, I have a small but annoying problem. When I open the DSP_BIOS.tcf file in CCStudio v3.3, it was called as a text file. But I want to make it open with the help of Configuration Tool. What are the setting for this should be in CCStudio v3.3? You should be able to right click...

    Hi Brad, I am looking into your question and trying to find the patch. Are you able to upgrade to a newer version of BIOS? This problem was fixed way back in 2001. Regards, Harry

    FYI, we've intentionally decoupled the IDE from the other components such as the code generation tools and DSP/BIOS to enable you to upgrade the IDE without affecting the actual code. You should be able to update to the latest version of CCS and install the exact same code generation tools, DSP/BIOS...

    Brad Griffis
    The BIOS documentation doesn't show support for "long long" with LOG_printf. As a workaround you could output two variables. Perhaps something like this would work: LOG_printf(&output, "%x %x", var>>32, var); Let us know if that works.

    You need to remove the cdb file from your project and add the tcf file instead.

  • Forum Post: Re: Problems on the DDK uart

    TimHarron
    Matthew, Are the files actually being created in the same folder as the .tcf file? Is the folder marked as "Read-Only" by chance?" The reason Brad mentioned removing the .cdb file is that your build log shows the .cdb file instead of the .tcf file. The .s62 and _c.c files are both generated...

    Brad Griffis
    LOG_printf does indeed allow you to pass variables at run-time. It does so using RTA/RTDX so that you don't need to halt. You're right that CCS grabs the string from the out file, but it will format and insert the data values that were passed from the target.

  • Forum Post: C6424 compared to DM6437. Similar enough to run DSP/BIOS Link on C6424?

    KrzysztofCh
    I've recently received C6424 EVM and it's very similar to DM6437 (EVM and chip). Since DSP will be part of system with ARM I wanted to try DSP/BIOS Link for interprocessor communication. In the DSP/BIOS Link user guide it is mentioned that Linux PC <-> DM6437 is supported so I was wondering...

    I believe the correct symbol name should be "_ECM_dispatchTab" - can you confirm the symbol name you posted? This error generally occurs when the ECM is disabled inside DSP/BIOS. If using the graphical editor go to Scheduling->HWI->ECM, right click Properties and select "Enable event...

    Thanks for the quick reply! Indeed, I did do that. In this test program, there is only one source file, though there are some files (a .c and a .s62 file) generated by the DSP/BIOS. To handle the .c file, I had to specify the -fg option to compile C files as C++, but that doesn't address the assembly...

    An update: It appears to me that the exception handling code is not properly destroying exception objects. (This may be a symptom of a deeper problem, but it may just as well be the problem itself.) Here's what I did. I lock a global mutex in my exception class's constructors and unlock it...

    Georgem Unfortunately, you have wandered into unsupported territory. C++ exception handling uses a data structure, not exposed to the user, to do its job. There is only one copy of this data structure in the system. The different tasks are all modifying this one data structure. Changes made by one task...

    Thanks, Bernie. However, the issue with using the DVEVM update site is that it does not seem to have all of the needed tools, at least that seemed to be my impression when I was trying to get everything installed (perhaps that is not the case, though). There do seem to be compatibility issues with using...

    Georgem I have since learned more of the low level details of how exception handling works in the TI compiler. There is persistent state about exceptions that each task presumes is only modified by that task. Putting a mutex around each point where that state is updated is not sufficient. That merely...

    Performing all the exception throws and catches in a single task should (and I emphasize should) work. Build all the non-throwing tasks code without --exceptions. So your answer is that task switching itself is not the problem, which means, contrary to your previous statement, that one can indeed use...

    Georgem I never said whether the task switch itself is the cause the problem. BTW, the task switch itself is not the cause of the problem. At this point, I'm beginning to doubt I'll ever explain this to your satisfaction. It's not that I'm implacable. It's just that I am trying...
