L4T R32.5.0 Notes
As of 03 Feb 2021, the master branch supports L4T R32.5.0/JetPack 4.5 content for all current Jetson platforms.
NVIDIA documentation:
Names of machine configuration files have change to match the updated naming convention in L4T R32.5.0. The main change is that
all of the machine names now include devkit, to make it clearer that they correspond to developer kits rather than bare modules.
Machine names unchanged from the last release are jetson-nano-2gb-devkit, jetson-xavier-nx-devkit, and jetson-xavier-nx-devkit-emmc.
| Old name | New name |
|---|---|
| jetson-tx1 | jetson-tx1-devkit |
| jetson-tx2 | jetson-tx2-devkit |
| jetson-tx2i | jetson-tx2-devkit-tx2i |
| jetson-tx2-4gb | jetson-tx2-devkit-4gb |
| jetson-nano-qspi-sd | jetson-nano-devkit |
| jetson-nano-emmc | jetson-nano-devkit-emmc |
| jetson-xavier | jetson-agx-xavier-devkit |
| jetson-xavier-8gb | jetson-agx-xavier-devkit-8gb |
On the Nano developer kit, all boot-related partitions have been relocated to the QSPI flash in R32.5.0. Only the rootfs partition gets written to the SDcard.
The Linux kernel in R32.5.0 has changed from being based on 4.9.140 to 4.9.201.
The U-Boot in L4T R32.5.0 changed from a base of U-Boot v2016.07 to U-Boot v2020.04. The meta-tegra layer
switched to upstream U-Boot starting with the dunfell-l4t-r32.4.3 branch (and is at v2020.07 in gatesgarth
and v2020.10 in master), but relevant patches added by NVIDIA for the L4T release have been ported to our
branches.
Only minor updates were made in JetPack 4.5, with little impact on recipes in meta-tegra.
