Build RPi image locally

If you are developing or want to modify the starting RPi image, you’ll want to build the image locally. Follow the relevant instructions for your system.

NixOS

  1. Enable QEMU emulation of aarch64 by adding the following to your configuration.nix 
    boot.binfmt.emulatedSystems = [ "aarch64-linux" ];
  2. Build the RPi SD image with: 
    nix build .#rpi-image

Note

This builds the initial RPi SD image using the sd_card_configuration.nix configuration. This image has the bare necessities to get started, keeping it small. If you want to build the final image from configuration.nix, update flake.nix accordingly before running nix build.
