TechNexion Camera Modules for NVIDIA JetPack 4.6
Instruction
TechNexion Embedded Vision Solutions provide embedded system developers access to high-performance, industrial-grade camera solutions to accelerate their time to market for embedded vision projects.
We are no longer maintaining JetPack 4.6.x
We don't maintain the camera drivers for JetPack 4.6.x anymore. To use the latest drivers for TechNexion cameras on Jetson Nano, you will need to port the drivers from supported driver branches.

Bring up Camera by GStreamer
If you succeed in initialing the camera, you can follow the steps to open the camera.
- Check the supported resolutions:

- Bring up the camera (/dev/video0) with 1280x720 by Gstreamer pipeline:
DISPLAY=:0 gst-launch-1.0 v4l2src device=/dev/video0 ! "video/x-raw, format=(string)YUY2, width=(int)1280, height=(int)720" ! xvimagesink sync=false
Troubleshooting
1. Cannot Find Cameras
If you cannot bring up the cameras, you can check if the video device does exist.
$ ls /dev/video* # List all video devices
/dev/video0 /dev/video1
If you cannot see the devices, you should check if the drivers have been probed.
2. Occur Error: Could not get EGL display connection
If you occurred the errors nvbufsurftransform: Could not get EGL display connection by rununing the Gstreamer command, you can modify the parameter 'DISPLAY' by the command:
# Check and Set environment parameter for 'DISPLAY'
$ export DISPLAY=$(w| tr -s ' '| cut -d ' ' -f 3 | grep :)
# Run Gstreamer pipeline
$ gst-launch-1.0 v4l2src device=/dev/video0 ! "video/x-raw, format=(string)YUY2, width=(int)1280, height=(int)720" ! xvimagesink sync=false
