    please refer VisionSDK_UserGuide_opencx.pdf to build and run openCL demos.
    Did you make any chances in VSDK or just trying to rebuild and run the demos?
    BTW, which openCL Usecase/demo you are trying out?

    regards, Shiju

    Dear Shiju,

    You means we need to rebuild the openCL demos?
    Currently I am following VisionSDK_Linux_UserGuide.pdf to build with: MAKECONFIG=tda2xx_evm_linux_opencl

    After build successfully, and launching on sd card as:
    $> cd /opt/vision_sdk
    $> ./load_ocl_kos.sh (needed only for opencl usecases)
    $> source ./opencl_env.sh (needed only for opencl usecases)
    $> source ./vision_sdk_load.sh
    $> ./$(MAKEAPPNAME).out

    Then I select the 1st available OpenCL use case to run.

    So this will not work if not rebuild OpenCL demo following VisionSDK_UserGuide_opencx.pdf ?

    Thanks and best regards

    Sorry, We had an issue with OpenCL, as the openCL demos on A15 Linux are broken from VSDK 3.2 onward due a non-compatibility issue between Linux Kernel and openCL pre-built package. OpenCL on A15 linux is depreciated from VSDK 3.2 release onwards

    regards, Shiju
