Debug information :

VPSS_CORE : failed to register ti81xx-vpss driver

    Where exactly this vpss.ko module is located?

    In DM814x EZSDK, this vpss.ko module is located in the root filesystem, and the command to load it is:

    modprobe vpss sbufaddr=0xBFB00000 mode=hdmi:1080p-60 i2c_mode=1

    The vpss.ko is located at: rootfs/lib/modules/2.6.37/kernel/drivers/video/ti81xx/vpss/vpss.ko

    Regards,
    Pavel
