How to Build Linux 6.12 for Nvidia Jetson AGX Orin

What is this?

• This is a guide to build a Linux 6.12 for Nvidia Jetson AGX Orin Developer Kit 32GB with Jetpack 6.2 (r36.4.3) and flash it on external storage.
• Currently, Jetpack 6.2 does not support Linux 6.12, and the patch below still contains a lot of bugs. Use this document for experiments only.
• Since display output is not supported, use the debugging serial port until SSH connection is established. This requires two cable connections between the host and the target device: one for data connection and one for debugging serial connection. For details on using the serial port, refer to here.

✅ Working

• Booting
• Serial Port (USB Micro-B)
