Hi, all:
I try to evm the EVM board by testing it function capture-display loopback.
After reading
http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/153145.aspx#554472
I known I should use v4l2 driver to run the saLoopBack, but it fail
root@dm816x-evm:/usr/share/videobin# ./saLoopBack
VPSS_GRPX : please stop grpx0 before continue.
failed to open capture device
Error in opening capture device for channel 0

/dev/video1 /dev/video2 /dev/video3
It seem there is no file "/dev/video0"
Should I use the mknod command to create the file by hand?
Anthoer question is how to demo the capture-display function by open-max ?
I try a omtb script but it seems not work, it is below:
