These instructions will take you through the step by step process of building and flashing a custom build of the Coreboot ROM to a Chromebook C201.

This guide expects you to have a Chromebook C201, and another ARM computer with Ubuntu installed. Specifically I used the Odroid XU2. You may be able to do this on an Intel platform, using a cross compiler. See the sidenotes section for more information.

Setting up your Ubuntu

Install dependancies

Update your Ubuntu aptitude and install the dependancies we will need.

sudo apt update

        $(NIX_PATH=nixos-config=./example.nix:$NIX_PATH \
          nix-build --no-out-link -E '
            with import <nixpkgs/nixos> {};
