BSP Upgrade#
This section covers how to upgrade between supported L4T minor revisions using APT.
Important
Upgrading to r39.2 is not supported through the APT steps below. To move to r39.2, use one of the installation methods described in the Quick Start Guide or the BSP Installation section: Jetson ISO, NVIDIA SDK Manager, or the Linux_for_Tegra flash script.

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
