    On my device, I see the following error message.

    PVR:(Error): SrvInit: PVRSRVInitSrvConnect failed (167) [0, ]
    /mnt/lg/res/lglib/pvrsrvctl: SrvInit failed (already initialized?) (err=167)

    Only platform is changed on the same SoC.
    The previous platform support OpenCL DDK.
    But present platform does not support OpenCL DDK, only support OpenGL.
    So I copied liboclcompiler.so and libPVROCL.so which are using in the previous platform to /usr/lib.
    Additionally, I found if libusc.so changes, OpenCL program works well, but nothing displayed on the screen.
    I think that is OpenCL vs OpenGL driver collision problem.
    I don’t know what the hell happened.
    Could you guys tell me what is libusc.so?
    I am working with IMG G6230 320MHz.

    Hi,

    It sounds like you’re asking a low level driver query – if you’re still having issues, could you contact DevTech@imgtec.com so we can redirect your query to the correct place?

    Regards,
    Tobias
