Can not restore nvme with Orin Nano

I am trying backup and restore functions on my custom board, the module is Jetson Orin Nano 8G, jetpack is 5.1.1.
I use the following command to flash my board
sudo BOARDID=3767 BOARDSKU=0003 ./tools/kernel_flash/ --external-device nvme0n1p1 -c ./tools/kernel_flash/flash_l4t_external.xml -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" --showlogs --network usb0 p3509-a02+p3767-0000 nvme0n1p1
Then, I use the following command to backup
sudo ./tools/backup_restore/ -b p3509-a02+p3767-0000
No problems until this step, I formatted the nvme on the custom board to ext4, and then restored nvme using the following command
sudo ./tools/backup_restore/ -r p3509-a02+p3767-0000
It fails with partx: specified range <1:0> does not make sense
I have tried several times to restore, and replaced the USB cable, but it doesn’t work, can anyone help?
Here is some logs
flash_log.txt (92.1 KB)
device_log.txt (82.0 KB)
PS:I have changed mmcblk0 to nvme0n1 in and, changed mmcblk0p1 to internal in, before I did the restore and backup.

Apply this patch:

Or manually download 35.5 and replace Linux_for_Tegra/tools/backup_restore/ with the one you get in the 35.5 BSP.


Thanks for your solution, I’ll test it later.

The nvme restore works fine, awesome!
