Create and customize a flake.nix
file:
{
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.
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.
