Updating Jetson Linux with Image-Based Over-the-Air Update

This wiki will use the reComputer J3010 as an example to demonstrate how to update Jetson linux from jetpack5.1.3 to jetpack6.0 with image-based over-the-air.

Prerequisites​

  • reComputer J4012/ J4011/ J3010 or J3011
  • Ubuntu 20.04 Host Computer
  • USB Type-C data transmission cable
info

Here, we use the reComputer classic series for demonstration. Other series of reComputers can also follow this tutorial to achieve OTA firmware upgrades.

1 Generate the System Image of JP5.1.3​

1.1 Prepare JP5.1.3 BSP​

First, you need to open a terminal window on the host PC and execute the following command to download the NVIDIA Jetpack 5.1.3 version BSP.

cd <root_dir>
mkdir jp5 && cd jp5
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
note

Where <root_dir> is the root directory of the project.

1.2 Build System Image of JP5.1.3​

Run the following command in the terminal window of the host PC to build the 5.1.3 system image.

tar xf jetson_linux_r35.5.0_aarch64.tbz2
sudo tar xpf tegra_linux_sample-root-filesystem_r35.5.0_aarch64.tbz2 -C Linux_for_Tegra/rootfs/
cd Linux_for_Tegra
sudo ./apply_binaries.sh
sudo  BOARDID=<BOARDID> BOARDSKU=<BOARDSKU> FAB=<FAB>  BOARDREV=<BOARDREV> CHIP_SKU=<CHIP_SKU> ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_nvme.xml  -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml --no-systemimg" --no-flash  --massflash 5  --network usb0  jetson-orin-nano-devkit  external
info
Jetson BOARDID BOARDSKU FAB BOARDREV CHIP_SKU
Orin Nano 4G 3767 0004 300 N.2 00:00:00:D6
Orin Nano 8G 3767 0003 300 N.2 00:00:00:D6
Orin Nx 8G 3767 0001 300 M.3 00:00:00:D4
Orin Nx 16G 3767 0000 300 G.3 00:00:00:D3

Please replace the corresponding variables based on the specific Jetson module you are using. For reComputer J3010: sudo BOARDID=3767 BOARDSKU=0004 FAB=300 BOARDREV=N.2 CHIP_SKU=00:00:00:D6 ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_nvme.xml -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml --no-systemimg" --no-flash --massflash 5 --network usb0 jetson-orin-nano-devkit external

Upon successful compilation, a system image package will be generated in the Linux_for_Tegra directory.

1.3 Flash the JP5.1.3 to Device (Optional)​

If you want to test this firmware on the Jetson device, you can refer to this wiki to flash the firmware into the Jetson device.

sudo tar xpf mfi_jetson-orin-nano-devkit.tar.gz
cd mfi_jetson-orin-nano-devkit
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --flash-only --massflash 1 --network usb0 --showlogs

2 Generate the OTA Package of JP6.0​

2.1 Prepare the BSP​

You need to open a terminal window on the host PC and execute the following command to download the NVIDIA Jetpack 6.0 version BSP.

cd <root_dir>
mkdir jp6 && cd jp6
wget https://developer.nvidia.com/downloads/embedded/l4t/r36_release_v3.0/release/jetson_linux_r36.3.0_aarch64.tbz2
wget https://developer.nvidia.com/downloads/embedded/l4t/r36_release_v3.0/release/tegra_linux_sample-root-filesystem_r36.3.0_aarch64.tbz2
wget https://developer.nvidia.com/downloads/embedded/l4t/r36_release_v3.0/release/ota_tools_R36.3.0_aarch64.tbz2

2.2 Build System Image of JP6​

Please refer to the steps in 1.2 for execution, and pay attention to modifying the variables therein.

tar xf jetson_linux_r36.3.0_aarch64.tbz2
sudo tar xpf tegra_linux_sample-root-filesystem_r36.3.0_aarch64.tbz2 -C Linux_for_Tegra/rootfs
cd Linux_for_Tegra
sudo ./apply_binaries.sh
sudo BOARDID=<BOARDID> BOARDSKU=<BOARDSKU> FAB=<FAB> BOARDREV=<BOARDREV> CHIP_SKU=<CHIP_SKU> ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_nvme.xml -p "-c bootloader/generic/cfg/flash_t234_qspi.xml --no-systemimg" --no-flash --massflash 5 --network usb0 jetson-orin-nano-devkit external

2.3 Generate OTA Payload Package​

Execute the following commands in the terminal window of the host PC.

cd <root_dir>/jp6
tar xf ota_tools_R36.3.0_aarch64.tbz2
cd Linux_for_Tegra
sudo BASE_BSP=<root_dir>/jp5/Linux_for_Tegra ./tools/ota_tools/version_upgrade/l4t_generate_ota_package.sh --external-device nvme0n1 -S 80GiB jetson-orin-nano-devkit R35-5

After the command finished. You will get the ota_payload_package.tar.gz in Linux_for_Tegra/bootloader/jetson-orin-nano-devkit.

3 Apply OTA Package on Device​

3.1 Prepare work​

Copy the generated OTA package(ota_payload_package.tar.gz) to the Jetson device, and execute the following commands in the terminal window of the Jetson device.

scp <...>/jp6/Linux_for_Tegra/bootloader/jetson-orin-nano-devkit/ota_payload_package.tar.gz ~
wget https://developer.nvidia.com/downloads/embedded/l4t/r36_release_v3.0/release/ota_tools_R36.3.0_aarch64.tbz2
sudo mkdir /ota
sudo mv ~/ota_payload_package.tar.gz /ota
tar xf ota_tools_R36.3.0_aarch64.tbz2

3.2 Apply OTA​

cd ~/Linux_for_Tegra/tools/ota_tools/version_upgrade
sudo ./nv_ota_start.sh /ota/ota_payload_package.tar.gz

After this command finished successfully. Reboot the device.

Finally, the device upgrade from 5.1.3 to 6.0 successfully.
