# zephyr-nix
|
|
|
|
Develop Zephyr projects using Nix
|
|
|
|
## Features
|
|
|
|
* SDK packaging
|
|
* `sdk`
|
|
|
|
The minimal SDK.
|
|
Can be overriden with additional targets.
|
|
|
|
``` nix
|
|
sdk.override {
|
|
targets = [
|
|
"arm-zephyr-eabi"
|
|
];
|
|
}
|
|
```
|
|
|
|
* `sdkFull`
|
|
|
|
SDK with all targets enabled.
|
|
|
|
* Host tools packaging
|
|
|
|
* `hosttools`
|
|
|
|
Binary `hosttools` from the Zephyr SDK.
|
|
Because of libc incompatibilities not all binaries in this derivation actually works.
|
|
|
|
* `hosttools-nix`
|
|
|
|
A re-packaging of the Zephyr SDK hosttools using nixpkgs packages.
|
|
|
|
## Basic usage
|
|
|
|
- `shell.nix`
|
|
|
|
``` nix
|
|
{ mkShell
|
|
, zephyr
|
|
, callPackage
|
|
, cmake
|
|
, ninja
|
|
, lib
|
|
}:
|
|
|
|
mkShell {
|
|
packages = [
|
|
zephyr.pythonEnv
|
|
# Use zephyr.hosttools-nix to use nixpkgs built tooling instead of official Zephyr binaries
|
|
zephyr.hosttools
|
|
cmake
|
|
ninja
|
|
];
|
|
|
|
env.ZEPHYR_SDK_INSTALL_DIR = zephyr.sdk.override {
|
|
targets = [
|
|
"arm-zephyr-eabi"
|
|
];
|
|
};
|
|
}
|
|
```
|
|
|
|
## Flakes usage
|
|
|
|
- `flake.nix`
|
|
``` nix
|
|
{
|
|
description = "A very basic Zephyr flake";
|
|
|
|
inputs = {
|
|
nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
|
|
|
|
# Customize the version of Zephyr used by the flake here
|
|
zephyr.url = "github:zephyrproject-rtos/zephyr/v3.5.0";
|
|
zephyr.flake = false;
|
|
|
|
zephyr-nix.url = "github:adisbladis/zephyr-nix";
|
|
zephyr-nix.inputs.nixpkgs.follows = "nixpkgs";
|
|
zephyr-nix.inputs.zephyr.follows = "zephyr";
|
|
};
|
|
|
|
outputs = { self, nixpkgs, zephyr-nix, ... }: let
|
|
pkgs = nixpkgs.legacyPackages.x86_64-linux;
|
|
zephyr = zephyr-nix.packages.x86_64-linux;
|
|
in {
|
|
devShell.x86_64-linux.default = pkgs.mkShell {
|
|
# Use the same mkShell as documented above
|
|
};
|
|
};
|
|
}
|
|
```
