You should only back up the rootfs partition. The other content is more or less a signed version of what would be the BIOS on a PC. If you have something custom, then you could of course backup individual partitions, but otherwise it would be pointless.
A typical clone (from “
~/nvidia/nvidia_sdk/JetPack...version.../Linux_for_Tegra/” of the host PC would go like this:
- Connect the USB-C cable to the PC.
- Put the Xavier in recovery mode.
sudo ./flash.sh -r -k APP -G my_backup.img jetson-tx2 mmcblk0p1"
This would produce sparse file “
my_backup.img” and raw file “
my_backup.img.raw”. Placing a copy of either clone into “
Linux_for_Tegra/bootloader/system.img”, and then flashing while using the option to “reuse” the image would restore the system (be sure the release of JetPack used for original flash is also the release you restore from).
