    Hi,

    Could you please tell me what the exact use-case is? Are you trying to run OpenCL use-cases using Vision-SDK (VSDK)?
    What version of VSDK are you using? Whats the configuration used to build VSDK?

    Regards
    Shravan

    Hello Shravan:

    1.  the running case is from

    and we just remove the display of Pangolin.

    1. the visionSDK is 03_04_00_03 from
    2. the configuration used to build VSDK is MAKECONFIG?=tda2px_evm_linux_all
    3. and we check the post above and also failed to run /usr/bin/ti-mct

    Hello,


    Can you explain how do you end up calling this CMEM api?
    Where are you using VIsion SDK wrt to the git repo you have mentioned?

    Can you provide call stack of where this is getting called from in the application?
    You can run with gdb to get backtrace

    Regards,

    Hi,

    Sorry for the delayed response. We had discussion about the problem and I can summarize it as follows:
    After VSDK 3.2 release OPENCL usecase has some issue on linux configuration.
    This is a known issue and has been mentioned in release notes of VSDK 3.4 with a JIRA-ID ADASVISION-1894.
    The features you try to use haven’t been fully tested / supported. While the issue seems to be on kernel, specifically
    Open-CL calls to the cmem driver, the team here isn’t aware of the workings of Open-CL on VSDK and/or how
    memory is managed using CMEM.

    Regards,
    Yordan

    Hi Yordan:
    From visionSDK 3.04, For TDA2Px, OpenCL is removed, did TI have plan to support it?
    We expect to use OpenCL to manipulate the DSP and GPU.

    TI__Genius 13395 points
    Hello
    OpenCL is deprecated from VSDK 3.2 onwards. This is because of some non-compatibility issue between the Linux Kernel/CMEM and openCL prebuilt libs. We do not support rebuilding on these libs and hence no plan to resume this support for any VSDK future releases

    regards, Shiju
