Linux/PROCESSOR-SDK-TDAX: Failed to run OpenCl examples on TDA2x using VISION SDK

Linux/PROCESSOR-SDK-TDAX: Failed to run OpenCl examples on TDA2x using VISION SDK

Part Number: PROCESSOR-SDK-TDAX


Tool/software: Linux

Hi,

Version of Vision SDK : PROCESSOR_SDK_VISION_03_03_00_00

I have followed all the steps given in TDA2x User Guide. 

MAKECONFIG?=tda2xx_evm_linux_opencx

ti-cgt-c6000_8.1.0/bin path is present in system PATH

make linux

make linux_install

make –s –j depend

make –s –j 

Build is successfull.

Also to flash SD Card , I followed the step given in same userguide.

Board is booting successfully.

I am not  able to execute this example /usr/share/ti/examples/opencl/vecadd, getting cmem error with ti-mctd

and when i am  running : ./ti-mctd

Error : CmemAllocator::CmemAllocator(): Assertion `msmc_alloc_dsp_addr_ == msmc_addr' failed.

I have attached boot log here for more information.

My main intersest is to run simple opencv example with opencl ON and opencl OFF to check opencv performance with dsp offloading.

I also tried with

MAKECONFIG?=tda2xx_evm_linux_all. 

I am getting same error.

Error in Log:

    Hi Sagar,

    it seems that the cmem.ko module is missing from your filesystem.
    Please follow chapter "1.1 Building cmem" in VisionSDK_UserGuide_opencx.pdf (and referred there wiki and VisionSDK_Linux_UserGuide.pdf ) to build and install cmem module.

    Regards,
    Yordan

    Hi Yordan,

    Is it cmemk.ko or cmem.ko
    I can see cmemk.ko is generated and it is present in /opt/vision_sdk folder

    Also,

    I can see 3 folders

    /media/ee209200/rootfs/lib/modules/4.4.84-00105-gc66ba60-dirty/extra
    - cmemk.ko not present

    /media/ee209200/rootfs/lib/modules/4.4.84-00105-gc66ba60e1092-dirty/extra
    - cmemk.ko not present

    /media/ee209200/rootfs/lib/modules/4.4.84-g742f84423d/extra
    - cmemk.ko is present here

    and from boot log , we can see board has chosen Linux version 4.4.84-00105-gc66ba60-dirty to load the modules.

    Hi Sagar,

    you are right - it is cmemk.ko.
    Did you followed the steps in "4.3 Run demos" from VisionSDK_Linux_UserGuide.pdf - there are some scripts such as "load_ocl_kos.sh", "opencl_env.sh", etc. that needs to be run in order to prepare environment for OpenCL usecases.

    Hi Yordan,

    I tried that also .

    I am guessing the error is due to ti-mctd not loading during boot. Because, ti-mctd should load and initialize while booting as per the other e2e thread for opencl to work properly.

    Hi Sagar,

    I am not sure about this error, I have pinged VisionSDK experts to help how to run OpenCL.
