Remove opinionated configuration that doesn't belong in a hardware module README: home-manager setup, user/SSH configuration, example hardware-configuration.nix, and an overly complex multi-host flake pattern. Keep only the ODroid M1-specific information: how to build the SD card image with the required petitboot populateRootCommands, and how to set up the flake for ongoing nixos-rebuild switch.

# ODroid M1

Hardware support for the Hardkernel ODroid M1: https://www.hardkernel.com/shop/odroid-m1-with-8gbyte-ram/

## Building an SD Card Image
|
|
|
|
To create an initial SD card image for installation:
|
|
|
|
```nix
|
|
# flake.nix
|
|
{
|
|
inputs = {
|
|
nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
|
|
nixos-hardware.url = "github:nixos/nixos-hardware/master";
|
|
};
|
|
outputs = { self, nixpkgs, nixos-hardware }: rec {
|
|
nixosConfigurations.m1 = nixpkgs.lib.nixosSystem {
|
|
modules = [
|
|
"${nixpkgs}/nixos/modules/installer/sd-card/sd-image-aarch64.nix"
|
|
nixos-hardware.nixosModules.hardkernel-odroid-m1
|
|
./sdimage.nix
|
|
{
|
|
nixpkgs.hostPlatform.system = "aarch64-linux";
|
|
# Uncomment if cross-compiling from x86_64:
|
|
# nixpkgs.buildPlatform.system = "x86_64-linux";
|
|
}
|
|
];
|
|
};
|
|
images.m1 = nixosConfigurations.m1.config.system.build.sdImage;
|
|
};
|
|
}
|
|
```
|
|
|
|
```nix
|
|
# sdimage.nix
|
|
{ config, ... }:
|
|
{
|
|
imports = [ ./common.nix ];
|
|
|
|
sdImage = {
|
|
compressImage = false;
|
|
# Required for the system to boot
|
|
populateRootCommands = ''
|
|
${config.boot.loader.petitboot.populateCmd} -c ${config.system.build.toplevel} -d ./files/kboot.conf
|
|
'';
|
|
};
|
|
}
|
|
```
|
|
|
|
```nix
|
|
# common.nix
|
|
{ pkgs, ... }:
|
|
{
|
|
services.openssh.enable = true;
|
|
|
|
environment.systemPackages = [ pkgs.git ];
|
|
|
|
users.users.odroid = {
|
|
isNormalUser = true;
|
|
extraGroups = [ "wheel" ];
|
|
initialPassword = "odroid";
|
|
# openssh.authorizedKeys.keys = [ "ssh-ed25519 AAAA..." ];
|
|
};
|
|
}
|
|
```
|
|
|
|
Build with:
|
|
|
|
```sh
|
|
nix build .#images.m1
|
|
```
|
|
|
|
## Ongoing Configuration
|
|
|
|
After booting the SD card image, run `nixos-generate-config` to generate
|
|
`hardware-configuration.nix` for your system. Then set up your configuration
|
|
flake:
|
|
|
|
```nix
|
|
# flake.nix
|
|
{
|
|
inputs = {
|
|
nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
|
|
nixos-hardware.url = "github:nixos/nixos-hardware/master";
|
|
};
|
|
outputs = { nixpkgs, nixos-hardware, ... }: {
|
|
nixosConfigurations.m1 = nixpkgs.lib.nixosSystem {
|
|
modules = [
|
|
nixos-hardware.nixosModules.hardkernel-odroid-m1
|
|
./common.nix
|
|
./configuration.nix
|
|
./hardware-configuration.nix
|
|
];
|
|
};
|
|
};
|
|
}
|
|
```
|
|
|
|
The module configures petitboot as the boot loader, so `nixos-rebuild switch`
|
|
works as usual.
