No capture device (/dev/video0) on i.MX6Q Sabre

I have an i.mx6q evk board (sabre) and ov5640 camera. I build a bsp 3.0.35 for imx6q sabresd.

But I can't find video 0 or 1 in /dev/. What do I need to do to generate /dev/video0 or /dev/video1.

I need 3.0.35 to verify some things. So I can't change other bsp version.

Sorry, I have already solved this problem.

I need to install ov5640_camera.ko and install V4L2 capture device.ko.

And I can find the /dev/video0 and /dev/video1

Thank you for your reply. Attached is the log file.

I tested on NXP EVK board. (i.MX6 Series SABER for Smart Devices). ov5640 is on J5 (Parallel Port).

refer to your logfile,

camera ov5642 is not found
camera ov5640_mipi is found

it seems that your board detect ov5640 as mipi already, pls double check it

Yes, system detected as mipi camera. I need to manually insert the V4L2 driver. The system will show video 0 and video 1.
