TDA4 : Find difference output between evm and PC-emulation by using vision_apps with custom layer

Ted Chang

Dear Sir,

I am using psdk_rtos_auto_j7_06_02_00_21 and trying to make the model with custom layer.

The layer-level output of evm is same as PC-emulation. The config setting are flowctrl = 16 on evm and flowctrl = 20 on PC-emulation .

I guess that model has already pass the TIDL standalone test.

  

When I try to change the model in app_tidl. I got the different outputs between evm and PC-emulation.

The output from evm is same as TIDL standalone test.

When I remove the custom layer, all of the outputs are same.

  

So, my questions are:

In my opinion, the outputs from app_tidl should be the same between PC-emulation and evm. 

What's the problems may happen and how to figure it out?

The following files are models and configs that I made from TIDL:

with_custom_layer.zip  without_custom_layer.zip

Thanks and Regards,

Ted

    Hi Ted,

    Can you share the changes you made in app_tidl to run custom layer?

    Hi Rishabh:

      

    I've added the following line in tiovx/lernels_j7/tidl/dsp/:

    tidlObj->createParams.TIDLWriteBinToFile = tivxKernelTIDLDumpToFile;

    + ) tidlObj->createParams.TIDL_CustomLayerProcess = TIDL_customLayerProcess;

        

    Then I modify STATIC_LIBS and LDIRS  in some concerto.mak files.

    1.psdk_rtos_auto_j7_06_02_00_21\tiovx\kernels_j7\concerto_inc.mak
    +  STATIC_LIBS += tidl_custom
    +  LDIRS+= $(PSDK_PATH)/tidl_j7_01_01_00_10/ti_dl/lib/PC/dsp/algo/$(TARGET_BUILD)

    2.psdk_rtos_auto_j7_06_02_00_21\vision_apps\apps\concerto_x86_64_inc.mak
    +  STATIC_LIBS += tidl_custom
    +  LDIRS+= $(PSDK_PATH)/tidl_j7_01_01_00_10/ti_dl/lib/PC/dsp/algo/$(TARGET_BUILD)

    3.psdk_rtos_auto_j7_06_02_00_21\tiovx\psdkra_tools_path.mak
    +  TIDL_CUSTOM_PATH ?= $(PSDK_PATH)/tidl_j7_01_00_00_10/ti_dl/custom

      

    In main.c, I turn on the  APP_TIDL_TRACE_DUMP.

    Then, I disable the function displayOutput and change the following line in readInput function.

    uint32_t offset = ((16 + i) * 256) + 16;  ->   uint32_t offset = i* 256;

    resizeImage(pInPlanes, pOutPlanes, img_width, img_height, img_width, 256, 256, 256); ->
    resizeImage(pInPlanes, pOutPlanes, img_width, img_height, img_width, img_width, img_height, img_width); 
       
    chOffset = 256*256; -> chOffset =img_height * img_width;
       
       
    But I consider the changes that won't be the problem.

    Because the layer-level trace are different between PC-emulation and evm.

    The difference is happened in the next layer-index of custom layer.

       

    Thanks,

    Ted

    Hi Rishabh:

      

    When I set flowctrl=2 in TIDL inference config, I got the same output between app_tidl on PC-emulation and TIDL standalone on PC-emulation.

    When I set flowctrl=20 in TIDL inference config, I got the different output between app_tidl and TIDL standalone on PC-emulation.

    Maybe this clue can help.

    Thanks,

    Ted

    Hi Ted,

    Can you clarify "I guess that model has already pass the TIDL standalone test".

    Can you confirm if the model working in standalone?

    What happens when you set flowCtrl = 1 between app_tidl and TIDL_standalone?

    Regards,

    Rishabh

    Hi Rishabh:

      

    I've already solve this problm.

    It caused by the bad memory declared in tidl_custom.

      

    Thanks and Regards,

    Ted
