Hi zhj18115188906,

Are you using the devkit or custom board for Xavier NX?
What’s the Jetpack version in use?(R35.4.1?!)

nvrestore_partitions.sh: You are trying to flash images from a board model that does not
match the current board you're flashing onto.

Could you share the result of the following command on your board?

$ cat /etc/nv_boot_control.conf
