Create a Pure JetPack 6.0 DP Environment

! In most case, please use the JP6.0 Production Release Page!

Sometimes, a minor version upgrade in SDKManager can lead to confusion. As a result, we prefer to establish a clean L4T environment on the host computer independently of the SDKManager.

According to NVIDIA's public information, JetPack 6.0 is based on Jetson Linux 36.2. You can find all the necessary file links to create a BSP, kernel sources, and a sample rootfs (root file system) at https://developer.nvidia.com/embedded/jetson-linux-r362

After following the steps outlined below, you will have the L4T folder ready for device tree and kernel compilation.
