Installation

​
Prerequisites

  • NVIDIA Jetson Orin Nano (support for additional modules coming soon)
  • JetPack 6 (L4T R36.x)
  • Internet connection for downloading packages

​
Install

curl -fsSL https://pixi.sh/install.sh | sh
If your system doesn’t have curl, use wget: 
wget -qO- https://pixi.sh/install.sh | sh
This downloads the latest jnc binary, places it in ~/.pixi/bin, and adds it to your PATH.
Restart your terminal after installation for the PATH changes to take effect.

​
Verify Installation

After restarting your terminal, verify jnc is installed and detect your Jetson hardware: 
jnc --version
jnc probe
The probe command should report your Orin Nano hardware, L4T version, JetPack version, and CUDA capabilities.

​
Alternative Installation Methods

Download From GitHub Releases

jnc is a single executable with no external dependencies. Download the aarch64 archive from the GitHub releases, unpack it, and add it to your PATH.

​
Install From Source

jnc is written in Rust and can be built with cargo:
