# raspberry-pi-nix
|
||||||
|
|
||||||
|
NixOS modules that make building images for raspberry-pi products
|
||||||
|
easier. Most of the work in this repository is based on work in
|
||||||
|
[nixos-hardware](https://github.com/NixOS/nixos-hardware) and
|
||||||
|
[nixpkgs](https://github.com/NixOS/nixpkgs). Additionally, be aware
|
||||||
|
that I am no expert and this repo is the product of me fooling around
|
||||||
|
with some pis.
|
||||||
|
|
||||||
|
This flake provides nixos modules that correspond to different
|
||||||
|
raspberry-pi products. These modules can be included in nixos
|
||||||
|
configurations and aim to deliver the following benefits:
|
||||||
|
|
||||||
|
1. Configure the kernel, device tree, and u-boot in a way that is
|
||||||
|
compatible with the hardware.
|
||||||
|
2. Provide a nix interface to device tree configuration that will be
|
||||||
|
familiar to those who have used raspberry-pi's config.txt based
|
||||||
|
configuration.
|
||||||
|
3. Make it easy to build an image suitable for flashing to an sd-card,
|
||||||
|
without a need to first go through an installation media.
|
||||||
|
|
||||||
|
The important modules are `overlay/default.nix`, `rpi/default.nix`,
|
||||||
|
and `rpi/device-tree.nix`. The other modules for i2c, i2s, etc are
|
||||||
|
mostly wrappers that set common device tree settings for you.
|
||||||
|
|
||||||
|
## Example
|
||||||
|
|
||||||
|
```nix
|
||||||
|
{
|
||||||
|
description = "raspberry-pi-nix example";
|
||||||
|
inputs = {
|
||||||
|
nixpkgs.url = "github:NixOS/nixpkgs/nixos-21.11";
|
||||||
|
raspberry-pi-nix = {
|
||||||
|
url = "github:tstat/raspberry-pi-nix";
|
||||||
|
inputs.nixpkgs.follows = "nixpkgs";
|
||||||
|
};
|
||||||
|
};
|
||||||
|
|
||||||
|
outputs = { self, nixpkgs, raspberry-pi-nix }:
|
||||||
|
let
|
||||||
|
inherit (nixpkgs.lib) nixosSystem;
|
||||||
|
basic-config = { pkgs, lib, ... }: {
|
||||||
|
time.timeZone = "America/New_York";
|
||||||
|
users.users.root.initialPassword = "root";
|
||||||
|
networking = {
|
||||||
|
hostName = "basic-example";
|
||||||
|
useDHCP = false;
|
||||||
|
interfaces = { wlan0.useDHCP = true; };
|
||||||
|
};
|
||||||
|
hardware.raspberry-pi = {
|
||||||
|
i2c.enable = true;
|
||||||
|
audio.enable = true;
|
||||||
|
fkms-3d.enable = true;
|
||||||
|
deviceTree = {
|
||||||
|
dt-overlays = [{
|
||||||
|
overlay = "imx477"; # add the overlay for the HQ camera
|
||||||
|
args = [ ];
|
||||||
|
}];
|
||||||
|
};
|
||||||
|
};
|
||||||
|
};
|
||||||
|
in {
|
||||||
|
nixosConfigurations = {
|
||||||
|
rpi-zero-2-w-example = nixosSystem {
|
||||||
|
system = "aarch64-linux";
|
||||||
|
modules = [ raspberry-pi-nix.rpi-zero-2-w basic-config ];
|
||||||
|
};
|
||||||
|
rpi-4b-example = nixosSystem {
|
||||||
|
system = "aarch64-linux";
|
||||||
|
modules = [ raspberry-pi-nix.rpi-4b basic-config ];
|
||||||
|
};
|
||||||
|
};
|
||||||
|
};
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Building an sd-card image
|
||||||
|
|
||||||
|
An image suitable for flashing to an sd-card can be found at the
|
||||||
|
attribute `config.system.build.sdImage`. For example, if you wanted to
|
||||||
|
build an image for `rpi-zero-2-w-example` in the above configuration
|
||||||
|
example you could run:
|
||||||
|
|
||||||
|
```
|
||||||
|
nix build '.#nixosConfigurations.rpi-zero-2-w-example.config.system.build.sdImage'
|
||||||
|
```
|
||||||
|
|
||||||
|
## Other notes
|
||||||
|
|
||||||
|
The sd-image built is partitioned in the same way as the aarch64
|
||||||
|
installation media from nixpkgs: There is a firmware partition that
|
||||||
|
contains necessary firmware, u-boot, and config.txt. Then there is
|
||||||
|
another partition that contains everything else. After the sd-image is
|
||||||
|
built, nixos system updates will not change anything in the firmware
|
||||||
|
partition ever again. New kernels and device tree configurations will
|
||||||
|
remain on the nixos partition and be booted by u-boot in the firmware
|
||||||
|
partition.
|
||||||
|
|
||||||
|
So, while you can control device tree params and overlays through your
|
||||||
|
nixos system configuration, if you want to modify other config.txt
|
||||||
|
variables this must be done manually by mounting the partition and
|
||||||
|
modifying the config.txt file.
