With the release of JetPack 4.2.2, L4T 32.2.1 is now available for the NVIDIA Jetson Nano Developer Kit. Several of the JetsonHacksNano Github repositories on the JetsonHacksNano account have been updated to support this release.
Note that each of these repositories have associated releases to match the repository with the L4T version. You can find releases under the ‘releases’ tab on the Github repository. For example, a typical naming convention is vL4T32.2.1
In no particular order, here’s the repositories with updates.
buildKernelAndModules
This is a utility repository which aids in building the Linux kernel and modules. Several different repositories use this as the basis to build new kernel images. Note that the intended use is to use the repository scripts to download the kernel source files, compile the kernel, and compile the modules. Uses scripts/config to modify the .config file. Because you should be familiar with the Linux kernel make procedures, this is for advanced users only.
rootOnUSB
The scripts in this repository will setup a NVIDIA Jetson Nano Developer Kit to set the rootfs to a USB drive. See this article: Jetson Nano – Run from USB Drive.
installLibrealsense
Build and install Intel’s librealsense for the NVIDIA Jetson Nano Developer Kit. The librealsense project supports Intel RealSense cameras such as the T265 and D400x series cameras. The installLibrealsense repository can rebuild the Linux kernel and add the kernel modules if need be to support the Intel RealSense D400x series cameras. Now builds librealsense v2.25.0.
installRealSenseROS
Install the realsense-ros library on NVIDIA Jetson Nano Developer Kit. Installs RealSense ROS Version = 2.2.8, which expects a librealsense v2.25.0 installation.
