I’ll attach the operation I did with the official BSP. For the record, I did this backup operation on reComputer Industrial J4012, with JetPack 5.1.3. Similar operations can be performed on reComputer Industrial J3011. (I’m remoting to my native Ubuntu host machine)
- Download the Jetson Linux BSP and sample rootfs
mkdir backup_workspace
cd backup_workspace
wget https://developer.nvidia.com/downloads/embedded/l4t/r35_release_v5.0/release/jetson_linux_r35.5.0_aarch64.tbz2
wget https://developer.nvidia.com/downloads/embedded/l4t/r35_release_v5.0/release/tegra_linux_sample-root-filesystem_r35.5.0_aarch64.tbz2
And extract the file, assemble the rootfs
tar xf jetson_linux_r35.5.0_aarch64.tbz2
sudo tar xf tegra_linux_sample-root-filesystem_r35.5.0_aarch64.tbz2 -C Linux_for_Tegra/rootfs
cd Linux_for_Tegra
sudo ./apply_binaries.sh
- Download configuration files and necessary files for backup operation
wget -L https://raw.github.com/Seeed-Studio/Linux_for_Tegra/r35.5.0/recomputer-orin-industrial.conf -O recomputer-orin-industrial.conf
- Download BSP patch.
For reference, you should check the recomputer-orin-industrial.conf, find the corresponding files for your Jetson Module:
Usually these file can be found either on Nvidia’s base BSP, or this repo.
For different Jetson Orin series modules, here’s the module table reference:
Note that the Module ID/Module SKU/Chip SKU usually won’t change, but FAB or MODULE REVISION may differ for different batches. This is very important because as we explained, you can apply your backup to the same Jetson devices, or with different SSD, even the Jetson module in the same model and batch.
You can’t restore your backup to a Jetson module of same model but from different batch.
Now, for reComputer Industrial J4012, I found that I will need the following files, so I downloaded them from our repo:
# tegra234-p3767-0000-p3509-a02.dtb
wget -L https://raw.github.com/Seeed-Studio/Linux_for_Tegra/r35.5.0/kernel/dtb/tegra234-p3767-0000-p3509-a02.dtb -O bootloader/tegra234-p3767-0000-p3509-a02.dtb
# orin-nx-seeed-industry.dtbo
wget -L https://raw.github.com/Seeed-Studio/Linux_for_Tegra/r35.5.0/extra_scripts/recomputer_industrial/orin-nx-seeed-industry.dtbo -O bootloader/orin-nx-seeed-industry.dtbo
- Run backup command
Press the recovery button while attaching the power supply, set the device into force recovery mode and execute:
sudo ./tools/backup_restore/l4t_backup_restore.sh -e nvme0n1 -b recomputer-orin-industrial
