Device-specific notes

Building a full disk image

This platform uses the u-boot system-type. This means that a full disk image can be produced, and this full disk image flashed outright to the block device. That block device can be the internal eMMC or the SD card.

The PinePhone will boot from SD card if a bootloader can be found. This means that the full disk image can be flashed to an SD card, and it will prioritise booting it.

 $ nix-build --argstr device pine64-pinephone -A build.disk-image
 $ dd if=result of=/dev/mmcblkX bs=8M oflag=sync,direct status=progress

Building the boot partition

Building the full disk image may require a native AArch64 system.

The boot partition can be built, and then flashed on top of an existing Mobile NixOS boot partition.

 $ nix-build --argstr device pine64-pinephone -A build.boot-partition
 $ dd if=result/mobile-nixos-boot.img of=/dev/mmcblkXp1 bs=8M oflag=sync,direct status=progress

Building U-Boot

Flashing the boot partition will not affect the installed U-Boot bootloader.

U-Boot can be built and then flashed the usual way for Allwinner platforms.

 $ nix-build --argstr device pine64-pinephone -A build.u-boot
 $ dd if=result/u-boot-sunxi-with-spl.bin of=/dev/mmcblkX bs=1024 seek=8

Usage notes

LED

In the default setup, the LED has been configured to show status information. Its colour or pattern can be used to infer the status.

During boot:

  • Red as early as possible in our U-Boot build

  • Yellow when our U-Boot "boot script" ran

  • Green by the kernel whenever it sets it up

At any time:

  • The red LED will flash on panic

As it does not reset the other LED colours, it may flash green/yellow rather than off/red. If applications customize the LED status, it may flash in other patterns involving red.
