Hi,

Thanks for the information. I have been delving into this and I just found this:

i.MX6 OV5647 Bayer sensor driver (ERROR: v4l2 capture: mxc_v4l_dqueue timeout enc_counter 0)

It seems that you have the add the support in v4l2 layer besides the driver for your sensor.

Have you made one of these changes?

Best Regards,

Alejandro
