    Hello,

    What is the EZSDK version that you are using here?

    Is it 5.05.02?

    PVR_K: (FAIL) SGXInit: Mismatch in client-side and KM driver build options; extra options present in KM: (0x1). Please check sgx_options.h

    It seems to me that there is mismatch between the kernel and the graphic libraries.

    Best Regards,

    Margarita

    pvrsrvkm.ko

    1.The Linux kernel has to be built with "modules" support (make uImage modules)

    2.The kernel modules of the Graphics driver have to be built, after the linux kernel is built in the above manner. ie, the kernel modules need to match the kernel version that will actually run on the target.

    Let me know the result.

    Best Regards,

    Margarita
