Validated configuration

This guide has been validated on Jetson AGX Orin Developer Kit with JetPack 7.2, Linux for Tegra 39.2, and kernel 6.8.12-1021-tegra using the TechNexion JetPack 7.2 pre-built camera driver package.

Install TN Camera on Jetson AGX Orin Developer Kit

Adaptor for NVIDIA Jetson AGX Orin Developer Kit

Use the VL-GM2-AGX-8CAM adaptor for VLS-GM2 cameras on Jetson AGX Orin Developer Kit. For adaptor pinout and power details, see VL-GM2-AGX-8CAM.

Using TechNexion pre-built modules

info

Set up the Jetson AGX Orin Developer Kit with NVIDIA JetPack 7.2 first, then install the TechNexion camera driver package for JetPack 7.2.

Download pre-built modules.

wget https://download.technexion.com/demo_software/EVK/NVIDIA/OrinNano/pre-built-modules/latest/JP72/tn_camera_modules_jp72.tar.gz

Uncompress the modules.
```
tar -xf tn_camera_modules_jp72.tar.gz
```

Run the installation script.

cd tn_camera_modules_orin_nano_jp72_<release_time>/
sudo ./tn_install.sh

note

The driver package and extracted directory use OrinNano naming, but the same installer supports Jetson AGX Orin. Select Jetson AGX Orin when prompted.

Select the Jetson AGX Orin platform. VLS-GM2 is selected automatically because it is the supported camera module for this platform.

$ sudo ./tn_install.sh

After the camera initializes successfully, use the following commands to inspect and test it.

Check the supported resolutions:

$ gst-device-monitor-1.0 Video/Source

Verify a 1280x720 camera (/dev/video0) through the NVIDIA capture path without opening a display window:

$ gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 num-buffers=30 ! \
"video/x-raw(memory:NVMM), format=UYVY, width=1280, height=720, framerate=60/1" ! \
nvvidconv ! "video/x-raw(memory:NVMM), format=NV12" ! fakesink sync=false

Launch a 1280x720 camera (/dev/video0) via the GPU on the Jetson display:

$ DISPLAY=:0 gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! \
"video/x-raw(memory:NVMM), format=UYVY, width=1280, height=720, framerate=60/1" ! \
nvvidconv ! "video/x-raw(memory:NVMM), format=NV12" ! nv3dsink sync=false

Troubleshooting

Cannot Find Cameras

If you cannot bring up the cameras, check whether the video devices exist.

$ ls /dev/video*  # List all video devices
/dev/video0  /dev/video1  /dev/video2  /dev/video3
/dev/video4  /dev/video5  /dev/video6  /dev/video7

Check whether the camera drivers have been probed.

$ lsmod | grep -E 'tevs|max96724|max96717'
max96717               32768  8
tevs                   32768  0

You can also check whether the VLS-GM2 boot entry and the AGX Orin overlay are active after reboot.

$ grep -nE 'DEFAULT|LABEL|FDT|OVERLAYS' /boot/extlinux/extlinux.conf
DEFAULT tn-vls-gm2
LABEL tn-vls-gm2
      FDT /boot/tegra234-p3737-0000+p3701-0005-nv.dtb
      OVERLAYS /boot/tegra234-p3737-camera-vls-gm2-overlay.dtbo

Could not get EGL display connection or failed to start nv3dsink

If you encounter nvbufsurftransform: Could not get EGL display connection or nv3dsink: Failed to start when running the GStreamer command through SSH, run the command from the Jetson graphical session or set the display environment before launching the pipeline:

$ export DISPLAY=:0
$ export XDG_RUNTIME_DIR=/run/user/$(id -u)
$ gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! \
"video/x-raw(memory:NVMM), format=UYVY, width=1280, height=720, framerate=60/1" ! \
nvvidconv ! "video/x-raw(memory:NVMM), format=NV12" ! nv3dsink sync=false

If the display sink still cannot start from SSH, verify the camera capture path without opening a display window:

$ gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 num-buffers=30 ! \
"video/x-raw(memory:NVMM), format=UYVY, width=1280, height=720, framerate=60/1" ! \
nvvidconv ! "video/x-raw(memory:NVMM), format=NV12" ! fakesink sync=false
