# Creating an installation SD card image
|
|
|
|
Create and customize a `flake.nix` file:
|
|
|
|
```nix
|
|
{
|
|
inputs = {
|
|
nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
|
|
nixos-hardware.url = "github:nixos/nixos-hardware";
|
|
};
|
|
|
|
outputs = { nixpkgs, nixos-hardware, ... }:
|
|
let
|
|
supportedSystems = [
|
|
"x86_64-linux"
|
|
"aarch64-linux"
|
|
"riscv64-linux"
|
|
"x86_64-darwin"
|
|
"aarch64-darwin"
|
|
];
|
|
forAllSupportedSystems = nixpkgs.lib.genAttrs supportedSystems;
|
|
in
|
|
{
|
|
packages = forAllSupportedSystems (system: rec {
|
|
default = sd-image;
|
|
sd-image = (import "${nixpkgs}/nixos" {
|
|
configuration = {
|
|
imports = [
|
|
"${nixos-hardware}/milkv/pioneer/sd-image-installer.nix"
|
|
];
|
|
|
|
nixpkgs.buildPlatform.system = system;
|
|
nixpkgs.hostPlatform.system = "riscv64-linux";
|
|
|
|
system.stateVersion = "24.05";
|
|
};
|
|
inherit system;
|
|
}).config.system.build.sdImage;
|
|
});
|
|
};
|
|
}
|
|
```
|
|
|
|
Then build the image by running `nix build .#` in the same folder.
|
|
|
|
# Known issues
|
|
|
|
LinuxBoot will not output the boot menu on the serial console, only on the graphical console.
|
|
Unfortuately, it might also pick up boot options from other devices, e.g. an nvme or sata drive.
|
|
It might end up booting by default from those instead of booting from the SD card.
