Note: This guide is applicable to every GMSL2-enabled NVIDIA Jetson device, not only ZED Box.
The GMSL2 cameras, ZED X, ZED X Mini, and ZED X One require specific permissions to function correctly and transmit communication signals.
When creating a new user on the ZED Box, you need to grant the correct permissions to control the GMSL2 capture card behavior.
Open a new terminal console [Ctrl+Alt+t] and create a new user:
sudo adduser <username>
Log out the current user and then log in with the newly created one.
Open a new terminal console [Ctrl+Alt+t] and add the new user to the required user groups:
sudo usermod -aG adm i2c tty dialout sudo audio video gdm zed
Reboot the device and log in with the new credentials to ensure everything is working properly.
