Hello,
I am trying to interface AR1335 camera with a custom board. I am facing an issue here. both custom board and rzv2m evk registers and recognise the device alike.The custom board couldnt do video capture. I checked and compared the boot logs of both the boards and found out that v4l2-comctl called open() this was not present in the custom board. Can anybody please explain what is going wrong here?
custom board bootlog

Hi anzal,Did you use the same firmware (same kernel, rootfs and dtb) for both boards?Can you see this file on your rootfs: /bin/comctld ? What is the output of the command: cat /lib/modules/$(uname -r)/modules.builtin ?Kind Regards.
