NixOS on ODROID-N2

These are configuration files which make it easier to set up and maintain a NixOS installation on an ODROID-N2+ single-board computer.

The system is set up to be loaded through Petitboot, which means the physical boot switch on the board must be in the 'SPI' position (the ODROID's are shipped with Petitboot installed in the internal SPI flash memory). Petitboot reads kernel path and boot options from a /kboot.conf file.

Kernel is mainline.

Patches are welcome!

Building an initial SD/MMC image

On an aarch64 system (or with aarch64 emulation):

nix-build '<nixos/nixos>' -I nixos-config=./sd-image.nix -A config.system.build.sdImage

First configuration

After flashing the image and booting it up on the ODROID:

nixos-generate-config # populates /etc/nixos/ with empty configuration
nix-env -iA nixos.gitFull
cd /etc/nixos
git clone https://github.com/povik/nixos-on-odroid-n2.git

# add ./nixos-on-odroid-n2 as an import in configuration.nix, modify the configuration in other ways

nixos-rebuild switch

...and you are set!

Known Bugs

• Reboots seem not to work. The system shuts down but then it's stuck and does not restart.
