Status
@dezgeg's porting efforts to ARMv7 works on the Orange Pi PC, using the proper upstream u-boot.
U-boot support has been merged 2017-12-11. The bootloader with SPL can be downloaded from those locations:
uboot-orangepi_pc_defconfig-****.**_u-boot-sunxi-with-spl.binautomatically built by Dezgeg (preferred).- Built originally when the pull request was made.
Board-specific installation notes
First follow the generic installation steps to get the installer image on an SD card.
U-Boot needs to be copied to specific sectors on the microSD card with dd. Download u-boot for the board (uboot-orangepi_pc_defconfig-2017.11.nixpkgs.*.u-boot-sunxi-with-spl.bin), and copy it to the correct location with (again, replace /dev/sdX with the correct path to the SD card device):
sudo dd if=uboot-orangepi_pc_defconfig-2017.11.nixpkgs.*.u-boot-sunxi-with-spl.bin of=/dev/sdX bs=1024 seek=8
Then, install using the installation and configuration steps.
Serial console
Your configuration.nix will need to add console=ttyS0,115200n8 to the boot.kernelParams configuration to use the serial console.
/etc/nixos/configuration.nix
{ config, pkgs, lib, ... }:
{
boot.kernelParams = [
"console=ttyS0,115200n8"
];
}
Compatibility notes
- Using the upstream kernel at 4.13, neither HDMI nor Ethernet will work.
- #29569 has a comment with a compatible linux kernel overlay derivation.
- Support for ethernet may land in 4.15.
- HDMI support isn't in the maintainer's requirements, it may start working in the future.
