Before flashing the image, use <code>unzstd</code> to unpack the downloaded archive.

If you want to use an alternative filesystem for system root, for example [[Btrfs]], you could change the <code>sdImage</code>-part to this
{{file|flake.nix|nix|<nowiki>
sdImage = {
  compressImage = false;
  rootFilesystemCreator = "${pkgs.path}/nixos/lib/make-btrfs-fs.nix";
  # do this manually as replacing the resize2fs string in postBootCommands
  # might be too complex. btrfs uses its own resize command.
  expandOnBoot = false;
};
nixpkgs.overlays = [
  (final: prev: {
    ubootVisionFive2 = prev.ubootVisionFive2.overrideAttrs (oldAttrs: {
      extraConfig = (oldAttrs.extraConfig or "") + ''
        CONFIG_FS_BTRFS=y
        CONFIG_CMD_BTRFS=y
      '';
    });
  })
];
</nowiki>}}
You might need to adjust [[U-Boot]] configuration if you wish to boot other filesystems or filesystem features.


It might be helpful to add [[RISC-V#Binary cache|third-party binary cache configuration]] to this system configuration.
