About README_backup_restore.txt

Originally in jetpack 4.6.1 I used ./nvmassflashgen.sh to create image backup files, but after jetpack 5.x.x it seems to be changed to other methods

I create an image backup file according to the file Linux_for_Tegra/tools/backup_restore/README_backup_restore.txt

but an error occurs

Waiting for target to boot-up...

Is this custom board or devkit?

custom board and devkit … both are the same

Hi channinglan,

Which Workflow are you follow up on README_backup_restore.txt?

Workflow 1: To create a backup image to host storage

Steps:

  • Make sure you have only ONE Jetson device in recovery mode plugged in the host
  • Run this command from the Linux_for_Tegra folder:
    $ sudo ./tools/backup_restore/l4t_backup_restore.sh -b

I run
./tools/backup_restore/l4t_backup_restore.sh -b jetson-agx-xavier-devkit

Last show TIMEOUT

Hi channinglan,

Please confirm there are only one Jetson device connect on host.
And run below command to try again:

$ cd /home/<username>/nvidia/nvidia_sdk/JetPack_5.0.2_Linux_JETSON_AGX_ORIN_TARGETS/Linux_for_Tegra/
$ sudo ./tools/backup_restore/l4t_backup_restore.sh -b jetson-xavier

Please see attachment
with the same error message

Also this message is that I am missing a package required for installation?

Please install the Secureboot package to use initrd flash for fused board

Hi channinglan,

Please download Secureboot package from here: Jetson Linux 35.1 | NVIDIA Developer
Then tar to Linux_for_Tegra folder and run it.

Will using Secure Boot lead to irreversible results??
Currently only want to backup with a successful image file

No, we are not enabling secure boot. Just some tools are inside secure boot tarball.
