Install A603 carrier board using backup and restore image (l4t_backup_restore.sh)

I am trying to install a batch of Jetson Orin Nano 8GB with A603 carrier board, using the backup and restore functionality briefly described on the wiki:

I have JetPack 6.1 installed.

Both the backup (first device) and the restore (on a second device) are successful.

But booting the second device takes very long and shows some errors:

So I have a few questions:

  1. Is backup and restore the proper way to install a batch of Jetson Orin Nano 8GB with the A603 carrier board?
  2. Why is the second device not booting properly?
  3. Are there other things that might not work properly on the device installed by restoring the image?

Regards,
Hans
