Cannot capture from ADV7281-M with i.MX6Q

Hi!

 

I am  trying to capture video stream from ADV7281-M with the i.MX6Q processor (UDOO Quad board). Unfortunately I can not use official AD driver (https://github.com/analogdevicesinc/linux/tree/adv7280) because have to use Kernel 3.0.35.

Currently I am trying with modified "adv7280_mipi_csi2_tvin" (I have added V4L2 routines to it). But unfortunately I always have (even with free run mode):

- ERROR: v4l2 capture: mxc_v4l_dqueue timeout enc_counter 0

 

I think the issue with my MIPI CSI settings...

 

Does anybody have any suggestions what is wrong?

 

Regards, Yury.

 

P/s/

I have enabled debug output in the sources, and below some registers values:
