Trying to use two TOF camera on Jetson Orin Nano

Nvidia Jetson Cameras
1
  1. Where did you get the camera module(s)?
    -Cytron
  2. Model number of the product(s)?
    -B0410
  3. What hardware/platform were you working on?
    -Nvidea Jetson Orin Nano
  4. Instructions you have followed. (link/manual/etc.)
    -Getting started: Arducam ToF Camera for Jetson - Arducam Wiki
  5. Problems you were having?
    -When I try to connect the TOF camera on the port cam0, it fails to read any data, the camera was able to initialise tho. There is no issue when I am using the port cam1. However, I will need to use both cam0 and cam1 port to operate two tof camera.
  6. The dmesg log from your hardware?
    -No
  7. Troubleshooting attempts you’ve made?
    -I changed the ros point cloud publisher code:Arducam_tof_camera/ros2_publisher/src/arducam/arducam_rclpy_tof_pointcloud/arducam_rclpy_tof_pointcloud/tof_pointcloud.py at main · ArduCAM/Arducam_tof_camera · GitHub
    -I was trying to access the cam0 port tof cam while connecting the two tof cam on port cam0 and cam1
    -the ls /dev/video* did give me two souces
    -So I changed the code above to open csi port 1, but then the code only publish empty data to the topic /point_cloud
  8. What help do you need?
    -An answer whether the tof camera support the cam0 port
    -An explaination whether it is possible for me to configure the use of TOF cam on port cam0 on jetson orin nano, if possible, how am I suppose to do so?

Any kind of reply please?

Hi there,
Unfortunately, what you are trying to do is not possible with the standard NVIDIA Jetson Orin Nano developer kit, due to a platform-level hardware limitation.

Here is a more detailed explanation:

  1. Driver System: Our ToF cameras connect to the Jetson platform using our “Jetvariety” driver system and adapter board.

  2. Carrier Board Limitation: Due to the physical wiring and signal routing on the official NVIDIA Orin carrier board, it can only support a single camera using the Jetvariety driver system at one time. This is a design constraint of the carrier board itself.

  3. Result: Consequently, even though the Orin Nano has two CSI connectors, only one ToF camera can be detected and operated by the system. The second camera will not be recognized.

This is a hardware constraint of the Jetson Orin developer kit’s carrier board and not an issue with the Arducam cameras or our software drivers.

We apologize that the current hardware setup does not support your dual-camera project needs.

Hi, thanks for your reply, to be clear, is it that the jetson could not recognise the tof camera from cam0 port at all (even under 1 tof cam connection only)? Or is it the board will only recognise either one from cam0 or cam1 when two ports are connected with arducam?

Also, do arducam have any multi cam kit board that support dual tof on a single port in Jetson Orin Nano?

Hi @TanYuJin
Thanks for the update.

Different carrier boards have different dedicated cam 1 ports. Cus I haven’t checked the photo of your Jetson Orin Nano, I can’t tell if it’s cam0 or cam1 that doesn’t work for you.

However, there’s a simple way to identify the working port—the one closest to the Power port on the Jetson Orin Nano.

A little heads up that your Jetson might detect another port; however, you can get nothing output from it.

Unfortunately, we don’t have it for now.
