WEC7 iMX6DL VPU firmware issues RRS feed

  • Question

  • In WEC7 VPU driver, there is a firmware used in form of bit_code array. I'm using same VPU driver (and same firmware) on iMX6Q and iMX6DL. On iMX6Q the code is fine, but on iMX6DL i'm facing error.

    Whether anybody worked on iMX6 VPU driver? Is there any change in drivers between Q and DL? I know this is particular to processor, but if anyone here worked on and know about the difference, please let me know.

    Error log:

    PID:06980012 TID:07C1001A ^5PID:06980012 TID:07C1001A >>> FSLVPUDecoder: WAIT_TIMEOUT - waiting for VPU interrupt at frame 0

  • In Linux there are two different BIN files are used for Q and DL. But these files (converted to hex array) are not working in WinCE. Did anyone had experience with VPU firmware? Or firmware for Quad worked directly on DualLite too?

    Thanks

    The people who probably know the answer to that work for companies who sell BSPs for iMX.6.  So, you should contact your BSP vendor.
