JetPack 5.0

Overview

JetPack 5.x (L4T 35.x) remains the baseline for AIR-030 production images. This document captures the shared build workflow and the device-specific flashing routine.

Platform Summary

• JetPack 5.0.2 / L4T 35.1.0 (reference release)
• Ubuntu 20.04 rootfs
• Kernel 5.10.104
• OS support list (Ubuntu 20)
• NVIDIA JetPack archives

Common Host Environment

• Recommended host OS: Ubuntu 20.04 with repo, git, and build essentials

• Install helper packages:

  sudo apt-get update
  sudo apt-get install -y repo git python3 curl binutils libxml2-utils qemu-user-static

• Optional: containerised builds using Docker

  docker pull advrisc/u18.04-imx8lbv1

Workspace initialisation

export GIT_SSL_NO_VERIFY=1
cd ~/BSP
mkdir -p jetson_linux_risc
cd jetson_linux_risc
git config --global user.name "Your Name"
git config --global user.email "you@example.com"

Launch Docker helper (optional)

sudo docker run -it --name jetson_linux_risc \
  -v /home/bsp/myLinux:/home/adv/BSP:rw \
  --privileged advrisc/u18.04-imx8lbv1:latest /bin/bash

Inside the container adjust ownership if required:

sudo chown adv:adv -R BSP

Manifest Selection

Use repo init with the manifest that matches the required JetPack release:

Release	Manifest XML	Notes
JetPack 5.0.2 / L4T 35.1.0	air030_3510.xml	Reference production release
JetPack 5.1.1 / L4T 35.3.1	air030.xml (repo branch main)	Includes incremental updates
JetPack 5.1.2 / L4T 35.4.1	air030.xml (35.4.1 manifest)	Latest 5.x fixes
JetPack 5.0.1 / L4T 34.1.1 (public)	3411.xml	Public board build

Example:

repo init -u https://AIM-Linux@dev.azure.com/AIM-Linux/risc_nvidia_jetson/_git/manifest -m air030_3510.xml
repo sync

For JetPack 5.1.x manifests hosted under version-specific repos, adjust the URL accordingly:

repo init -u https://AIM-Linux@dev.azure.com/AIM-Linux/risc_nvidia_jetson_35.3.1/_git/manifest -m air030.xml -b main
repo sync

Build Image

sudo ./scripts/build_release.sh -v <VERSION>

Omit the version argument for the default release artefact.

AIR-030 Flash Guide

1. Enter recovery mode
   Toggle SW2 to ON and press the power button.

   

2. Connect the device to a Linux host via USB-OTG and confirm enumeration:

   lsusb
   # Bus 001 Device 024: ID 0955:7223 NVIDIA Corp.

3. Unpack the release package:

   tar -zxvf air030_image_XXXXXX.tar.gz

4. Flash to eMMC (JetPack 5.x):

   cd bootloader
   sudo -s
   source flashcmd.txt

5. Flash to eMMC (JetPack 6.x compatibility builds):

   cd Linux_for_Tegra
   sudo ./flash.sh jetson-agx-orin-devkit mmcblk0p1

6. Flash to NVMe when supported:

   sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 \
     -c ./tools/kernel_flash/flash_l4t_t234_nvme.xml \
     -p "-c ./bootloader/generic/cfg/flash_t234_qspi.xml" \
     --showlogs --network usb0 jetson-agx-orin-devkit nvme0n1p1
