Hardware Manager

Flashing Jetson Nano Orin

It is easiest to do this on native Ubuntu.

Follow this guide to install the Nvidia sdkmanager

You may have to use the flash.sh script to get the super firmware which enables the MAXN SUPER power profile.

sudo ./flash jetson-orin-nano-devkit-nvme internal

It appears that when in recovery mode the carrier board does not spin the fan on the Jetson module, use an external fan to cool the module otherwise it may power off due to overheating.

Setting Up Jetson

• Disable desktop and misc services https://www.jetson-ai-lab.com/tips_ram-optimization.html
• Change fan curve to cool
• Update system
• Install/setup ROS2
• Install uXRCE-DDS
• Install/setup Tailscale

Flashing from Docker Container

Potentially useful tips:

• This must be done on a Linux machine (WSL2 might work according to the internet).
• Add "nfs" to your supported file systems and kernel modules
• Install udev in the container
• QEMU with aarch64-linux support must be installed on the host machine. On NixOS install QEMU system wide and add "aarch64-linux" to boot.binfmt.emulatedSystems. https://wiki.nixos.org/wiki/QEMU
• Run sudo update-binfmts --enable qemu-aarch64 in the container before launching the sdkmanager, you might have to install qemu-user-static before you run this (or after sdkmanger fails?).
