Hi,
We have an AGX Xavier board, and it keeps losing the home folder contents (/home/ubuntu). We suspect that it is happening after the reboot. This board is running L4T 35.5 with Ubuntu 20.04. Any suggestions on finding the root cause?
Get a serial console boot log. See if there are warnings or failures mentioned related to this. For example, if it is “repairing” the filesystem, then the repair itself might be removing home content for being inconsistent (which in turn would mean an incorrect shutdown, perhaps due to an app).
You could also create your home directory content, shut down, and then without normal boot put the Jetson into recovery mode. While in recovery mode you could clone the rootfs and then loopback mount the raw clone on your host PC and examine if the content is still valid (this would tell you if the content is still there after shutdown, but prior to boot since recovery mode does nothing to alter the memory and only turns the Jetson into a temporary custom USB device).
