Changes from L4T R36.5.0/JetPack 6.2.2 and R38.4.x/JetPack 7.1
This is the first JetPack release to support both the Orin family (AGX Orin, Orin NX, Orin Nano, previously supported in JetPack 6) and AGX Thor (T4000, T5000, previously supported only in JetPack 7).
See the release notes in the NVIDIA documentation for this release for information on new and updated features:
BSP changes
New machine configurations
Support for the AGX Thor platform is incorporated alongside Orin. New machine configurations added versus r36.x:
jetson-agx-thor-devkit— AGX Thor development kit (T5000 module, p4071 carrier)jetson-agx-thor-t4000— AGX Thor T4000 module installed in a p4071 carrier
Flashing process changes
Only initrd-flash is supported for flashing. See the Flashing page for
more information.
Security OS changes
OP-TEE gets an update to 4.6 with L4T R39.2. Hafnium (used on Thor only) is also updated. The Orin and Thor ARM TF-A firmware remains at their same respective base versions (different between the two platforms) as prior releases.
UEFI changes
The EDK2/UEFI source base has been updated for L4T R39.2, covering both Orin and Thor targets. For Orin users that have customized their UEFI configurations, note that configuration handling for UEFI builds in this release follows the updated approach used for Thor in R38.4, providing default ‘general’, ‘minimal’, and ‘simple’ configurations in-tree.
Kernel changes
Orin (Tegra234)
The kernel for Orin has been upgraded from linux-jammy-nvidia-tegra (5.15-based) to
linux-noble-nvidia-tegra (6.8.12-based). This is a significant kernel version upgrade.
A notable consequence of moving to the 6.8 kernel is that many Tegra ASoC audio drivers that were
previously delivered as out-of-tree modules (in the nvidia-kernel-oot-alsa package) are now
included in the mainline kernel. The following drivers have moved in-tree and are no longer
provided by the OOT package:
snd-soc-tegra186-asrcsnd-soc-tegra186-dspksnd-soc-tegra210-admaifsnd-soc-tegra210-adxsnd-soc-tegra210-ahubsnd-soc-tegra210-amxsnd-soc-tegra210-dmicsnd-soc-tegra210-i2ssnd-soc-tegra210-mixersnd-soc-tegra210-mvcsnd-soc-tegra210-opesnd-soc-tegra210-sfcsnd-soc-tegra-machine-driver
A smaller set of audio drivers (ADSP and virtualization-related) remains out-of-tree.
Thor (Tegra264)
Thor targets already used linux-noble-nvidia-tegra (6.8.12) in the R38.x branches. The kernel
base version is unchanged, but has been updated to the R39.2.0 L4T patch series.
Out-of-tree drivers
The out-of-tree kernel module package has been updated to R39.2.0, with compatibility updates for the 6.8 kernel across both Tegra234 and Tegra264 platforms.
JetPack changes
JetPack 7.2 includes significant component upgrades from JetPack 6.2.2:
| Component | JetPack 6.2.2 | JetPack 7.1 | JetPack 7.2 |
|---|---|---|---|
| CUDA | 12.6 | 13.0 | 13.2 |
| cuDNN | 9.3.0 | 9.12.0 | 9.20.0 |
| TensorRT | 10.3.0 | 10.13.3 | 10.16.2 |
PVA SDK and Nsight Systems have also been updated; see the NVIDIA release notes for version details.
Other new features
New recipes
SIPL/UDDF support
Recipes have been added for the SIPL API package and nvsiplcamerasrc GStreamer plug-in.
Consult the “Camera Development” chapter of the Jetson Linux Developer Guide for more information.
Jetson-IO support
The python3-jetson-io recipe has been added for installing the Jetson-IO tool
for runtime pin configuration. See [here](../extlinux.conf-support.md(#jetson-expansion-header-configuration-jetson-io)
for more information.
Container support
The nvidia-docker recipe has been removed. The nvidia-container-toolkit recipe provides
container runtime support; see NVIDIA Container Runtime Support for details.
