For more details on the update mechanism, see the official Jetson Linux Developer Guide:
Upgrading from r38.2.x to r38.4.x#
Follow these steps to upgrade your Jetson Thor from L4T r38.2.x to r38.4.x.
1. Check the Current L4T Revision#
First, verify your current L4T version:
cat /etc/nv_tegra_release
You should see output indicating R38 (release), REVISION: 2.x.
2. Backup and Update the APT Source List#
Before modifying the source list, create a backup:
sudo cp /etc/apt/sources.list.d/nvidia-l4t-apt-source.list /etc/apt/sources.list.d/nvidia-l4t-apt-source.list.bak
Update the source list to point to r38.4:
sudo sed -i 's/r38\.2/r38.4/g' /etc/apt/sources.list.d/nvidia-l4t-apt-source.list
Verify the change was applied correctly:
tail -n5 /etc/apt/sources.list.d/nvidia-l4t-apt-source.list
3. Perform the Upgrade#
Update the package list and upgrade:
sudo apt update && sudo apt upgrade -y
4. Reboot#
Reboot to apply the changes:
sudo reboot
5. Verify the Upgrade#
After reboot, confirm the upgrade was successful:
cat /etc/nv_tegra_release
You should now see R38 (release), REVISION: 4.x.
Tip
If something goes wrong during the upgrade, you can restore the original source list from the backup:
sudo cp /etc/apt/sources.list.d/nvidia-l4t-apt-source.list.bak /etc/apt/sources.list.d/nvidia-l4t-apt-source.list
