ADV7180 probing issue

Working on i.Mx6q based custom board. The kernel log shows following,

V4L2 device 'Mxc Camera' on IPU1_CSI0 registered as video0
ERROR: v4l2 capture: slave not found!

The ADV180 decoder worked when /unit_test/mxc_v4l2_tvin.out  run through command line. The video displayed on the screen. When simple opencv application of capturing video run, shows following error.
ERROR: v4l2 capture: slave not found!

Thanks and Regards,

Purvi Billore

Hi Purvi

if ADV180 decoder worked  fine with v4l2_tvin.out probably

there are problems with image, one can try to rebuild all from scratch

including opencv application.

Best regards
