CSI Camera Index


I have two CSI cameras connected to Jetson Xavier NX. I would like to find out which camera is connected to CAM_0 or CAM_1 on the board. I can only get the camera index when I run the ls /dev/video* command. Any help would be appreciated.

You can know which one by the i2c bus.
Check the bus by b4l2-ctl --list-devices like below, the bus number is 30,31,32 …
