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.

Sorry for having this problem. We will test as soon as possible.
Would it be possible to have a rough idea of the ETA? (Days/ Weeks/ Months?)
I have tested all the driver installation packages on the JetPack4.6 system, and this does not happen.
This could be caused by a driver issue on older systems. You can try to install JetPack4.6 to test.
Sorry, I don’t understand what you mean by ETA?
Sadly the IA program which I’m using with your camera cannot run on newer system, and I’m stuck on JetPack4.4…
For the ETA, I was just wondering if you had an idea if/how long it might take to find a fix for that (just to be able to plan things on my side!)
Hi, @yang @xiaotang
So no fix planned?
My colleague seems to have forgotten to reply in this thread.
I will arrange for him to help you test next week
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.
Ok thank you, I will see this issue with Nvidia, I hope they will be able to fix it, we wanted to use your camera on our jetson fleet
Edit: if someone has the same issue, the follow up thread on nvidia forum : Arducam driver deleting /proc/device-tree/serial-number - Jetson Nano - NVIDIA Developer Forums
I am also following this post in parallel, and solving this problem is also very helpful for me.
