I recently acquired a 4K HDR RS Zed X One camera with a Zed Link Mono Capture Card to use the camera with a Jetson Orin Nano. I followed the guides and managed to see the camera listed under
~$ v4l2-ctl --list-devices
NVIDIA Tegra Video Input Device (platform:tegra-camrtc-ca):
/dev/media0
vi-output, zedxone_uhd 10-001a (platform:tegra-capture-vi:1):
/dev/video0
After this point I tried to reach the camera stream with different utilities. The zed tools such as zedsrc, zed-capture and ZED_Diagnostics returned with the error CAMERA_NOT_DETECTED. I also tried different source elements on gstreamer such as nvarguscamerasrc, v4l2src but none work except the argus_camera application. It shows the camera stream and all other formats correctly.
What is wrong? I am using Jetpack 5.1.2, L4T 35.4.1 and here are the steps I followed during the driver installation.
- Connect the capture card and orin nano with a csi cable both unpowered.
- Connect the camera to capture card.
- Power the capture card and then orin nano.
- Install ZED SDK for Jetpack 5.1.2
- Download and install the driver from here for Zed X One 4K HDR , Zed Link Mono, JP 5.1.2
after this point I was able to see the camera under v4l2-ctl. Also theZED_Diagnostic --dmesgoutput
is here:

I see it says it is in use but nothing uses it and the argus_camera can open it.
