CCS/TDA3XEVM: How to debug switching of function execution in IPU.

Part Number: TDA3XEVM
Other Parts Discussed in Thread: SYSBIOS

Tool/software: Code Composer Studio

Hi,

I would like to know how to debug switching of function execution in IPU.

CCS has PC trace for A15 and DSP. However, IPU does not have PC trace. Is there any alternative method for IPU?

I am using processor SDK vision 3.00.

Regards,
Kenshow

    Hello Kenshow,

    You can use function profiling, task hooks instrumentation using sysbios UIA (system analyzer) module.
    Please refer to below for more details. Let me know if any more info needed.

    Refer to http://processors.wiki.ti.com/index.php/Processor_SDK_RTOS_PROFILING for  RTOS profiling details

    Hi Prasad,

    I checked sysbios UIA. However, I did not know how to set UIA into processor SDK vision3.00 referring to page 88 in spruh43f.pdf
    So, please advise me how to change specifically in the SDK.

    Regards,
    Kenshow

    Hello Kenshow,

    What is VSDK version you are using? We have added profiling support in the VSDK3.2 which you can enable using ENABLE_UIA_PROFILING flag in cfg.mk

    Hi Kenshow,

    We haven't heard back from you, I'm assuming you were able to resolve your issue.
    If not, just post a reply below (or create a new thread if the thread has locked due to time-out).

    Hi,

    I'm sorry for the late reply.

    The build succeeded.However, It did not worked as UIA debugging with TDA3x.
    I have interrupted it afterwards, but I will challenge next week and report them.

    Thanks,
    Kenshow

    Hi Prasad,

    I installed UIA version 2.00.5 50 under the folder C:\PROCESSOR_SDK_VISION_03_02_00_00\ti_components\os_tools. And, I tried to build for UIA with ENABLE_UIA_PROFILING flag in cfg.mk.
    However, It did not worked on TDA3x. the build is OK, but It seems that UIA for TDA3x was not included by ENABLE_UIA_PROFILING flag at the building.
    Could you advise me to build using UIA for TDA3x.

    In addition, I also tried to build for TDA2x. It has error as following:

    Hi,

    It works!
    For TDA3x, I found that it is not included UAI setting in BIOS_common.cfg.
    I added in the file as follows:

    if (enableProfiling == "yes")
    {
    BIOS.logsEnabled = true;
    var LoggingSetup = xdc.useModule('ti.uia.sysbios.LoggingSetup');
    LoggingSetup.sysbiosSwiLogging = true;
    LoggingSetup.sysbiosHwiLogging = true;
    LoggingSetup.sysbiosSemaphoreLogging = true;
    LoggingSetup.loadLogging = false;
    LoggingSetup.benchmarkLogging = false;
    LoggingSetup.mainLoggingRuntimeControl = false;
    LoggingSetup.loadTaskLogging = false;
    LoggingSetup.loadSwiLogging = false;
    LoggingSetup.loadHwiLogging = false;
    LoggingSetup.loadLoggerSize = 262144;
    LoggingSetup.sysbiosLoggerSize = 524288;
    LoggingSetup.mainLoggerSize = 262144;

    var UIAMetaData = xdc.useModule('ti.uia.runtime.UIAMetaData');
    UIAMetaData.overrideTimestampFreq = true;
    UIAMetaData.timestampFreq.lo = 20000000;
    }
    else
    {
    :
    }

    Is it OK for TDA3x? Especially, Logger size.

    Best regards,
    Kenshow

    Hello Kenshow,

    Yes, this configuration is fine for TDA3xx but it would not enable function level profiling. For enabling it please refet to below.

    Hello Prasad,

    Thanks for your advice. I'll try to use UIA on TDA3x.

    However, I have not solved about the compiling errors of TDA2x that I posted.
    Could you advise me to solve them.

    Best Regards,
    Kenshow

    Hello Kenshow,

    Are you getting below error? If yes, can you please increase  DSP1_DATA_MEM in apps/build/tda2xx/mem_segment_definition_bios.xs?

    "C:/PROCESSOR_SDK_VISION_03_02_00_00/vision_sdk/binaries/apps/tda2xx_evm_bios_all/obj/vision_sdk/tda2xx-evm/c66xdsp_1/release/vision_sdk_configuro/linker_mod.cmd", line 235: error:

    Hi Prasad,

    Yes.
    The build passed by changing in mem_segment_definition_bios.xs file as follows:

    /* EVE4_DATA_SIZE =13.5*MB; */
    EVE4_DATA_SIZE =13*MB;
    :
    /* DSP1_DATA_SIZE = 12.5*MB; */
    DSP1_DATA_SIZE = 13*MB;

    Thanks,
    Kenshow
