This article or section is out of date.
Reason: The information is likely outdated, but it is likely the ODROID-C2 works well. (Discuss in Talk:NixOS on ARM/ODROID-C2)
Once the page has been updated this notice can be removed. |
Status
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, you can build it with nix and then write it this fusing script (using an emmc/usb adapter) download and extract (replace /dev/sdX with the device for the eMMC):
nix-build '<nixpkgs>' -A pkgsCross.aarch64-multiplatform.ubootOdroidC2
cd result
bash /path/to/extracted/boot/sd_fusing.sh /dev/sdX
- Download the sd-image from Hydra at https://hydra.nixos.org/job/nixos/release-22.05-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:
Device Boot Start End Sectors Size Id Type

$ 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 console:
$ 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 console.
Xorg
Nixos 20.03 should install all modules needed for this to work but at least two changes should be made to the xorg configuration:
services.xserver.videoDrivers = [ "modesetting" ];
services.xserver.extraConfig = ''
Section "OutputClass"
Identifier "Meson"
MatchDriver "meson"
Driver "modesetting"
Option "PrimaryGPU" "true"
EndSection
'';
The HW cursor support was very laggy when tried on 20.03 so enabling the software cursor may be desired:
services.xserver.deviceSection = "Option \"SWcursor\" \"on\"";
