Troubleshooting

This troubleshooting guide provides solutions to common issues that may arise when using the ZED X One camera. If you encounter any problems, please refer to the sections below for potential fixes.

The camera is not detected #

GMSL2 cameras have lower flexibility compared to USB cameras. Any modification in the hardware configuration, such as plugging or unplugging a camera, or changing the camera order, requires either rebooting the Jetson, or restarting the installed daemon with the following command:

sudo systemctl restart zed_x_daemon

📌 Note: If you are using a custom carrier board, or a partner’s ECU, please make sure that the custom driver provides the zed_x_daemon service. If not, every hardware modification will require a reboot of the Jetson device.

Blurry images after system update #

After a system update, if you experience blurry images from the GMSL2 camera, it may be caused by the overwriting of a patched library used by the ZED Link driver.

To fix this issue, please follow this procedure to manually restore the patched library:

Download the latest ZED Link driver package for your device from the ZED X Drivers download page.
Extract the downloaded .deb package and copy the patched library to the correct location:
```
ar x stereolabs-zed<model>_<version>-<deser>-<l4t_version>_arm64.deb
tar xvf data.tar.xz
sudo cp ./tmp/R<l4t_version>/libnvisppg.so /usr/lib/aarch64-linux-gnu/tegra/libnvisppg.so
```
Replace stereolabs-zed<model>_<version>-<deser>-<l4t_version>_arm64.deb with the actual filename of the downloaded package.
Replace <l4t_version> with your current L4T version (for example, R36.4.3).
Reboot the Jetson device:
```
sudo reboot
```

After following these steps, the GMSL2 camera should function correctly with clear images.
