I’m using a Jetson Nano with Jetpack 4.4, and when I’m installing the driver with the automated install_full.sh, the ‘file’ /proc/device-tree/serial-number is removed at reboot. When I remove the driver (sudo dpkg -r arducam-nvidia-l4t-kernel) +reboot, the file reappear. The issue is I really need that file to execute some program.

I’m sorry. After our test, we suspect that it is a system problem. We have tested it on many versions of the system, and the same problem does not occur. So we suspect that it is a problem specific to the old version of the system.
We currently have no way to fix this problem, maybe you can ask Nvidia official.
