Status
ODROID-C2 support is being worked on by @grahamc. Mainline kernel from NixOS has been reported as working[1]. A non-specified build from mainline u-boot also has been reported to work.
Board-specific installation notes
Note this assumes u-boot is in partition 1 of your board's connected eMMC. If you haven't done that yet, read the backlog from https://logs.nix.samueldr.com/nixos-aarch64/2018-11-21#1738333; and also https://github.com/NixOS/nixpkgs/compare/master...samueldr:u-boot/odroid-c2.
- Download the sd-image from Hydra at https://hydra.nixos.org/job/nixos/release-18.09-aarch64/nixos.sd_image.aarch64-linux/latest
- Copy it to the SD card
- Mount first partition to /mnt with
sudo mount /dev/mmcblk0p1 /mnt - Edit /mnt/extlinux/extlinux.conf and delete all the console=tty.... arguments in the APPEND line
- Add
console=ttyAML0,115200n8to the end of the APPEND line
it will look something like this:
$ cat /mnt/extlinux/extlinux.conf
# Generated file, all changes will be lost on nixos-rebuild!
# Change this to e.g. nixos-42 to temporarily boot to an older configuration.

and then boot the sdcard.
Once booted, partition your on-board emmc like:

$ mkfs.ext4 /dev/mmcblk0p2
$ mkswap /dev/mmcblk0p3
$ swapon /dev/mmcblk0p3
$ mount /dev/mmcblk0p2 /mnt
$ nixos-generate-config /mnt
$ nixos-install
$ reboot
Serial console
I used minicom to access the serial:
$ cat /etc/minirc.odroid-c2
# Machine-generated file - use "minicom -s" to change parameters.
pu port /dev/ttyUSB0
pu lock /var/lock
pu rtscts Nothen run sudo minicom to access the serial console.
