i've trying to get image from camera sensor (attached bottom and front),

but I've been keep failing.

after following instruction,
https:/intel-aero/meta-intel-aero/wiki/90-(References)-OS-user-Installation
https:/intel-aero/meta-intel-aero/wiki/05-Autonomous-drone-programming-with-ROS

in here, I cant get image from /dev/video0 , dev/video2
https:/intel-aero/meta-intel-aero/wiki/06-Cameras-and-Video

C=10 INPUT=1 MODE=PREVIEW ./capture_v4l2 --userp -d /dev/video2
commands gives "VIDIOC_S_FMT error22, Invalid argument".

after some googling, I found about dmesg check and after that,
I think It might be problem of hardware.

so I format the drone and install intel-aero-image-1.6.2 and updated all firmware likes. (for check)
and after that, check kernel message(dmesg) gives me errors like attached photos.

is this meaning that my camera sensor has broken?
or some installation process is not done properly?

I'm waiting for your answers.
