1- How to get backup image from Jetson module
2- How to flash the backup image
In this blog post, we will clone a Jetson Orin NX module and restore another module with “l4t_backup_restore.sh” script file. First, we will put the it in Recovery Mode and clone the file system on NVME SSD. Then, we will restore to the target device with the same script file.
Attention: This guide is compatible for Jetson Orin Nano modules as well.
To get the backup image for Orin NX (or Orin Nano), there are 3 modifications on the script files. Open a terminal from the "Linux_for_Tegra" folder and type the following commands below:
sudo sed -i "s/mmcblk0p1/internal/g" tools/backup_restore/l4t_backup_restore.sh
sudo sed -i "s/mmcblk0/nvme0n1/g" tools/backup_restore/nvbackup_partitions.sh
sudo sed -i "s/mmcblk0/nvme0n1/g" tools/backup_restore/nvrestore_partitions.sh
Then, set the Jetson in recovery mode and connect it to the host PC. Afterwards, type "lsusb" and check the device coonected in Recovery Mode ("0955:7323 NVidia Corp." for Orin NX 16GB,
"0955:7423 NVidia Corp." for Orin NX 8GB,
"0955:7523 NVidia Corp." for Orin Nano 8GB,
"0955:7623 NVidia Corp." for Orin Nano 4GB)
Create the backup image with this command below:
sudo ./tools/backup_restore/l4t_backup_restore.sh -b jetson-orin-nano-devkit
A few seconds later, the script file will start the backup process.
At the end of the clone command, the backup images for each partition was created and the system is ready to restore to another Jetson module.
Set the Jetson module in recovery mode and type “lsusb”.
Now, burn the backup image with this command below:
sudo ./tools/backup_restore/l4t_backup_restore.sh -r jetson-orin-nano-devkit
A few seconds later...
At the end of the image burning process, the target device will ready to reboot.
