Using CSI camera on the Jetson Orin Nx 16GB does not work

Hello,
We encountered a problem with the Jetson Orin NX 16GB with our custom board:When we use two cameras with CSI channels CSI0 and CSI1, both works. However, with the same setup but a single camera on channel CSI0, it does not work. Closing CSI1 does not help.
To summarize:
One camera on CSI0 and another on CSI1: work;
One camera on CSI0, no camera on CSI1 but channel open: does not work;
One camera on CSI0, CSI1 closed: does not work.
By “work” I mean get the video stream from the camera.

We did some testing with one camera on CSI0 and CSI1 closed:
We were able to retrieve /dev/video0, and use cmd v4l2-ctl --device=/dev/video0 --get-fmt-video to read the camera parameters normally.
However, cmd v4l2-ctl --set-fmt-video=width=2592,height=1944,pixelformat=RG10 --stream-mmap --set-ctrl=sensor_mode=0 --stream-count=100 -d /dev/video0 gives no output and does not return or terminate.

Our jetpack version is 5.1.1. I also attached my Device Tree file, where the camera CSI channel is set to CSI0（mainly in file tegra234-camera-rbpcv2-ox05b1s.dtsi line 28, 57, 253）.

Hello @oliveira1,

A couple of questions:

  1. What happens if you connect 1 camera to CSI-1 and no camera to CSI-0 ?
  2. Can you share the output of dmesg in both 2 camera and 1 camera setups?
  3. What camera are you using?
  4. Did you develop the driver ?

regards,
Andrew

Using two camera working device tree and connect one camera to CSI0 to confirm the device tree.

Thanks
