JetPack 7.1

Overview​

JetPack 7.1 (Jetson Linux 38.4) is Advantech's next-generation baseline for NVIDIA Jetson platforms such as AIMB-294 carrier boards and the ASR-A702 rugged system. Both solutions now ship with Ubuntu 24.04, kernel 6.8.12, CUDA 13, and Thor-ready firmware so customers can evaluate AGX Thor compute while preserving a familiar Yocto-free workflow.

Platform Summary​

  • JetPack 7.1 (L4T 38.4.0)
  • Ubuntu 24.04 LTS with Wayland
  • Linux kernel 6.8.12 (PREEMPT_RT optional)
  • Supports Jetson AGX Thor-based AIMB-294, ASR-A702 and AIR-075 platforms

Build Environment on Host​

Host OS must be Ubuntu 20.04 or newer. Install Docker CE and pull the Advantech-maintained Jetson container.

sudo docker pull advrisc/u20.04-nvlbv2:20240515

Run container​

sudo docker run -it --name jetson_linux_risc \
  -v /home/bsp/myLinux:/home/adv/BSP:rw \
  --privileged advrisc/u20.04-nvlbv2:20240515 /bin/bash

# inside container (first launch)
sudo chown adv:adv -R BSP

Dependency library​

If you hit Exec format error during cross-flashing, install QEMU on the host (outside Docker):

sudo apt-get install qemu-user-static

Getting Linux Source Code​

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"
