JetPack 7.0 L4T R38.2.x Notes - OE4T/meta-tegra GitHub Wiki
As of 02 Nov 2025, no branches support JetPack 7.0/L4T R38.2.x.
There is a work-in-progress branch available for experimentation and early development. If you can help with testing features, fixing problems, etc., please join this Matrix room.
As of 01 Oct 2025, the WIP branch has been updated to L4T R38.2.1. As of 02 Nov 2025, the WIP branch has been updated to L4T R38.2.2. Note that R38.2.2 only updates some of the components; the rest remain at 38.2.1.
Changes from L4T R36.4.4/JetPack 6.2.1
This release introduces support for the Jetson AGX Thor development kit, and supports only AGX Thor targets. Machine configurations for the Orin family remain in the tree, but are not usable and not supported.
See the release notes in the NVIDIA documentation for this release for information on new and updated features:
- Jetson Linux R38.2 release notes
- Jetson Linux R38.2.1 release notes
- JetPack 7.0 download page (note that this link is not version-tagged)
Note that NVIDIA has not provided release notes for R38.2.2.
BSP changes
- Many changes are present to support Thor hardware.
Flashing process changes
Flashing in Jetson Linux for Thor targets is performed through a "unified" flashing process that is hidden under the L4T initrd/kernel flashing scripts.
For meta-tegra builds, after unpacking your tegraflash tarball, use initrd-flash while connected via USB to your Thor device to generate/sign the binary artifacts, stage them to a unified-flash workspace, and run the unified flashing scripts to flash the device. You can use ./initrd-flash --external-only to re-flash only the external (rootfs) drive, ./initrd-flash -k NAME to re-flash just the named partition, or ./initrd-flash --qspi-only to re-flash only the boot firmware in the QSPI flash. The script also takes a --debug option for enabling more verbose logging in the unified flashing tool.
See NVIDIA release notes and documentation for more information.
Kernel changes
The Linux kernel is now taken from the Ubuntu "Noble" release, and is based on Linux 6.8.12.
JetPack changes
JetPack 7.0 upgrades most of the JetPack content. See the NVIDIA documentation for more information.
DeepStream SDK
DeepStream 8.0 is available, but recipes for this are still TBD.
