 - Jetson ---> Target

  2. Environment Variables

${L4T_RELEASE_PACKAGE} contains the name of the Jetson Linux release package: Jetson_Linux__aarch64.tbz2.

${SAMPLE_FS_PACKAGE} contains the name of the sample file system package: Tegra_Linux_Sample-Root-Filesystem__aarch64.tbz2.

  1. To Flash the Jetson Developer Kit Operating Software

Download the latest Jetson Linux release package and sample file system for your Jetson developer kit from https://developer.nvidia.com/linux-tegra

Enter the following commands to untar the files and assemble the rootfs:

$ tar xf ${L4T_RELEASE_PACKAGE} $ sudo tar xpf ${SAMPLE_FS_PACKAGE} -C Linux_for_Tegra/rootfs/ $ cd Linux_for_Tegra/ $ sudo ./tools/l4t_flash_prerequisites.sh $ sudo ./apply_binaries.sh

  1. bootFromExternalStorage

These scripts were written before there was official support in the NVIDIA SDK Manager for booting from external storage. The NVIDIA SDK Manager is a tool used to flash and configure the Jetson. You may prefer to use the SDK Manager instead of these scripts. To get started with SDK Manager: https://developer.nvidia.com/nvidia-sdk-manager
