Do you use latest Jetpack 4.6.1 or 4.6.2? If not, we suggest upgrade the system and try. Besides, please plug in the camera in power off and boot up the system

yes. i use Jetpack 4.6.1

When i tried this command :
v4l2-ctl --list-devices

it shown :

Failed to open /dev/video0: No such file or directory

We suggest re-flash the system image through SDKManager and try again. Raspberry Pi camera v2 should work well on default system image. If it still fails after re-flashing, it is very likely the camera is broken.

okk thank you.
