Tool/software: Linux

Hi,

When i start to run opencv sample, i got following error.

CMEM Error: init: major version mismatch between interface and driver.
CMEM Error: needs driver version 0x4130001, got 0x4120000
TIOCL FATAL: The cmemk kernel module is not installed. Consult the OpenCL UserGuide at http://software-dl.ti.com/mctools/esd/docs/opencl/index.html

i follow the step in VisionSDK_UserGuide_opencx.pdf

How can i solve this problem?

Thanks,

Chen-Wei

    Hi Chen-Wei,

    Did you followed chapter "2.4.2.1.1 Clone kernel" from VisionSDK_Linux_UserGuide.pdf to clone and checkout the correct version of cmem?
    (from other E2E threads with the same error it looks that this might happen because the userspace library that uses cmem is build against different version of cmem.ko module)

    Regards,
    Yordan
