    Hello,

    What is the software release that you are using here?

    Failed to send version command to M3 0xfffffff0

    .....

    This error means wrong boot args.

    Could you try with : 

    notifyk.vpssm3_sva=0xBF900000

    Check your mem value as well.
    Could you try with the default bootargs.

    Are you rebuilt the kernel? If yes, you should copy also all the modules like syslink.ko, vpss.ko etc.

    Best Regards,

    Hello,

    These are the default bootargs

    console=ttyO0,115200n8 rootwait root=/dev/mmcblk0p2 rw mem=256M earlyprintk notifyk.vpssm3_sva=0xBF900000 vram=50M vmalloc=500M ti814xfb.vram=0:16M,1:16M,2:6M ip=off noinitrd

    Could you try to set the mem, vram vmalloc and vpssm3_sva?

    Best Regards,

    Margarita

    FYI: When I were migrating to IPNC RDK3.8 from 3.2, I saw such problems at the beginning as well.

    I remember the problem was not the vpss.ko itself, it's in the VPSS firmware.can you post the whole output from remote_debug? maybe you got some errors before the insmod operation.
