I have just now also tried using the backup and restore script in this repo: GitHub - Seeed-Studio/Linux_for_Tegra: Seeed Jetson reComputer && reServer default Image source code.š š š, specifically I checked out branch r35.3.1.
Unfortunately this also fails, albeit with a slightly different error:
Save initrd flashing command parameters to /home/nx/flash/seeed_l4t/Linux_for_Tegra-r35.3.1/tools/kernel_flash/initrdflashparam.txt
/tmp/tmp.5qku8cwBXw ~/flash/seeed_l4t/Linux_for_Tegra-r35.3.1
