| − | ODROID-C2 support is being worked on by '''@grahamc'''. Mainline kernel from NixOS has been reported as working<ref>https://logs.nix.samueldr.com/nixos-aarch64/2018-01-25#863144;</ref>. A non-specified build from mainline u-boot also has been reported to work.

| − | 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.

| |
| − | # Copy it to the SD card
| |
| − | # Mount first partition to /mnt with <code>sudo mount /dev/mmcblk0p1 /mnt</code>
| |
| − | # Edit /mnt/extlinux/extlinux.conf and delete all the console=tty.... arguments in the APPEND line
| |
| − | # Add <code>console=ttyAML0,115200n8</code> to the end of the APPEND line

| |
| − | $ 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.
