Nitrogen 6X - can not get cameras operational.

I received my Bounday Devices Nitrogen 6X board yesterday, together with the two OV5640 cameras (the parallel and MIPI versions).


I have since tried the bundled Yocto version, the Yocto Fido release and now I am on the 2015 release of Ubuntu Trusty, and under none of the versions have I managed to run the simplest gstreamer command taking input video from the cameras. The only improvement under Ubuntu is that HDMI finally works, but that is a secondary issue,


So, back to the cameras. With only the MIPI camera plugged in, this is what I run right after boot:


modprobe ov5640_camera_mipi

modprobe mxc_v4l2_capture

(the drivers do show up properly in lsmod afterwards)


sudo gst-launch imxv4l2src ! imxv4l2sink

However, the MIPI camera seems to be detected at boot:


dmesg | grep ov56          
ov5640_read_reg:write reg error:reg=300a                                  
camera ov5640 is not found

ov5642_read_reg:write reg error:reg=300a                                  

camera ov5642 is not found 



Could anyone advise me on what next to take? I have tried following similar threads in the past day and a half, but none of the suggestions applied to my case. Please let me know what extra info I can post.


Thank you very much in advance!
