-
-[NVIDIA® JetPack 6.2: Jetson Linux 36.4.3](https://developer.nvidia.com/embedded/jetson-linux-r3643)
-1. Download Jetson Linux Driver Package - [JetPack 6.2 BSP sources](https://developer.nvidia.com/downloads/embedded/l4t/r36_release_v4.3/release/jetson_linux_r36.4.3_aarch64.tbz2)

-3. Apply patches for kernel drivers, nvidia-oot module and tegra devicetree.
-4. Build cross-compile project on host (Build PC) or natively on target (Jetson).
-5. Apply build results to target (Jetson).
-6. Configure target.
