JetPack 6.2

Overview

JetPack 6.2 (L4T 36.4.3) is the current baseline for AIR-021, DS-015, and EPC-R7300 platforms. This guide consolidates build preparation, source retrieval, and flashing workflows for each device.

Platform Summary

• JetPack 6.2 (L4T 36.4.3)
• Ubuntu 22.04
• Kernel 5.15.148
• OS support list (Ubuntu 22)
• NVIDIA JetPack archives

Common Build Environment

Docker container

Currently we adopt Docker as the build environment. Use the advrisc/u20.04-nvlbv2 container to match the JetPack 6.2 toolchain.

docker pull advrisc/u20.04-nvlbv2

If you rely on legacy flows, the advrisc/u18.04-imx8lbv1 image remains available but is not required for JetPack 6.2.

Run container

Launch a container and mount your BSP workspace:

sudo docker run -it --name jetson_linux_risc \
  -v /home/bsp/myLinux:/home/adv/BSP:rw \
  --privileged advrisc/u20.04-nvlbv2:latest /bin/bash

Inside the container adjust ownership if needed:

sudo chown adv:adv -R BSP

Host dependencies

Install helper tools on the host when you encounter Exec format error or similar issues:

sudo apt-get update
sudo apt-get install flex
sudo apt-get install bison
sudo apt-get install qemu-user-static

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"

Getting Linux Source Code

Use the same manifest repository for all platforms and select the appropriate XML per device:

Device	Manifest XML	Notes
AIR-021	air021.xml	Current release manifest
DS-015	ds015.xml	Current release manifest
EPC-R7300	epcr7300.xml	Current release manifest
AFE-R750	afer750.xml	Current release manifest

repo init -u https://AIM-Linux@dev.azure.com/AIM-Linux/risc_nvidia_jetson_36.4.3/_git/manifest -m <manifest>.xml
repo sync

Replace <manifest> with the value for your target. For EPC-R7300 you can also pin to the tagged XML when required:

repo init -u https://AIM-Linux@dev.azure.com/AIM-Linux/risc_nvidia_jetson_36.4.3/_git/manifest -m epcr7300a1_uj06201_k0515148_nvona_8g.xml
repo sync

Build Image

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

Omit the -v option to build the default release package.

Device Guides

Follow the steps below after completing the common setup.

AIR-021

Manifest

repo init -u https://AIM-Linux@dev.azure.com/AIM-Linux/risc_nvidia_jetson_36.4.3/_git/manifest -m air021.xml
repo sync

Flash workflow

1. Change the JRCOVY1 switch to ON and press the power button to enter recovery mode.

2. Connect a Linux host to the AIR-021 with the USB flash cable and verify the device is detected:

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

3. Unpack the release tarball and enter the flashing tools:

   sudo tar -zxvf AIR-021_XXX.tar.gz
   cd Linux_for_Tegra

4. Flash JetPack 6.2 to the NVMe device:

   sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 \
     -c tools/kernel_flash/flash_l4t_external.xml \
     -p "-c bootloader/generic/cfg/flash_t234_qspi.xml" \
     --showlogs --network usb0 jetson-orin-nano-devkit-super internal

Manifest

repo init -u https://AIM-Linux@dev.azure.com/AIM-Linux/risc_nvidia_jetson_36.4.3/_git/manifest -m ds015.xml
repo sync

Flash workflow

1. Change the SW7 switch to ON and press the power button to enter recovery mode.

   

2. Connect a Linux host with the USB flash cable and confirm the device is detected:

   lsusb
