NixOS Images for Rockchip Based Computers

Flake to build images for Rockhip based computers that require custom uboot firmware. Utilizes sd-card installer build infrastructure from nixpkgs.

IMPORTANT

• Flakes are automaticaly updated every Monday. Because of that latest commit in the main branch may fail to build. Check out a tag associated with the latest release if you are looking for a tested revision of the flake.

Image Building

Installer

Check out flake.nix for the list of supported configurations. To build an installer sd-card image for desired platform using flake execute nix build github:nabam/nixos-rockchip#Quartz64A or nix build .#Quartz64A (Quartz 64 A in this example).

$ nix build github:nabam/nixos-rockchip#Quartz64A
$ sfdisk --dump result/sd-image/nixos-image-sd-card-*.img
label: dos
label-id: 0x2178694e
device: result/sd-image/nixos-image-sd-card-XXX-aarch64-linux.img
unit: sectors
sector-size: 512

result/sd-image/nixos-image-sd-card-XXX-aarch64-linux.img1 : start=       16384, size=       16384, type=da
result/sd-image/nixos-image-sd-card-XXX-aarch64-linux.img2 : start=       32768, size=     5585984, type=83, bootable

Built image then can be copied to sdcard or other memory:

$ sudo dd if=./result/sd-image/nixos-image-sd-card-*.img of=/dev/mmcblk0 iflag=direct oflag=direct bs=16M status=progress

When using installer run sudo NIX_CONFIG="experimental-features = nix-command flakes" nixos-install to get flakes based configuration. Following error will appear otherwise:

error: experimental Nix feature 'flakes' is disabled; use '--extra-experimental-features flakes' to override

Custom Image

Check out the example to see how custom images can be built with this flake. To build the example run: (cd example && nix flake update && nix build).

Cache

Build cache is available on Cachix: nabam-nixos-rockchip. Use it to speed up builds.
