Preparation

First, please download BSP package from internet. It's preferred to download BSP package, instead of Jetpack.

Go to https://developer.nvidia.com/embedded/linux-tegra.

The following packages are necessary:

L4T Driver Package (BSP)

Sample Root Filesystem

Source code for kernel and other components:

L4T Driver Package (BSP) Sources

Toolchain for kernel building:

GCC 7.3.1 for 64 bit BSP and Kernel

Secure package if secure-boot is necessary:

Jetson Platform Fuse Burning and Secure Boot Documentation and Tools


Refer to https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fquick_start.html

Then the device can be flashed by command line.

With this method, user can have more controls for the BSP configuration, like pinmux, kernel/kernel DTB customization, etc.
