NixOS on ARM/PINE64 Pinebook

PINEBOOK
Manufacturer	PINE64 (Pine Microsystems Inc.)
Architecture	AArch64
Bootloader	Upstream U-Boot
Boot order	SD, eMMC
Maintainer

The Pinebook (sometimes referred as pinebook-a64) is a laptop design based on the Allwinner A64 SoC. It was available in two sizes, 11.6" and 14", but is now only available as 11.6". The 11.6" has two resolutions, first models had a 1366×768 panel, while the more recent ones have a 1920×1080 panel.

It can boot from SD or from an included and replaceable eMMC module.

Status

Upstream NixOS AArch64 image boots on the PINE A64-LTS, using the proper upstream U-Boot.

U-boot support has been added 2019-05-18. The bootloader has not been built for now.

Installation instructions

To use the generic installation image for your board, you will need to copy it verbatim to an SD card.

sudo dd if=sd-image-aarch64-linux.img of=/dev/DEVICE conv=sync status=progress

This board requires the installation of u-boot at a specific location on the storage where NixOS was written to.

sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/DEVICE bs=1024 seek=8

Partitioning

The internal storage needs to be partitioned in a way that that the bootloader will not interfere with nor be interfered by a partition.

Then, continue installation using the installation and configuration steps.

By copying the sd image internally

This is an easy solution, that also allows booting and installing as one would from an SD card on a generic Allwinner platform. Simply dd the SD image to the internal storage. The internal storage is likely to be /dev/mmcblk2.

MBR partition scheme

This article or section needs expansion.

Reason: Installation instructions need to be written up to keep space for embedding the bootloader to the SPL. (Discuss in Talk:NixOS on ARM/PINE64 Pinebook#)
Please consult the pedia article metapage for guidelines on contributing.

GPT partition scheme

The Allwinner/GPT Installation page explains how to create a GPT partition table while allowing the isntallation of u-boot at the required offset.

Serial console

Details about the pinout for the headphone jack are available on the PINE64 wiki. It is also available on their store. The serial settings are the usual Allwinner settings.

On early models^[Which?] serial needs to be toggled via software. On recent models, a physical switch is present on the main board. The linux-sunxi wiki's Pinebook page has details about serial access.

Compatibility notes

Mainline kernel
HDMI	Hasn't been tested.

Downstream kernel

Note: Keep in mind that using non-upstream forks of the kernel always incurs some risk as far as security goes.

This article or section needs expansion.

Reason: Find and document use of a kernel with the added capabilities. (Discuss in Talk:NixOS on ARM/PINE64 Pinebook#)

USB booting with u-boot

You will need to either have mainline U-Boot installed to the eMMC or to an SD card.

Stop the boot process when prompted (by pressing a key). Then, do the following:

Hit any key to stop autoboot:  0
=> setenv boot_targets usb0
=> boot

This sets the boot order for this boot only. U-Boot can boot (among others) either of the NixOS sd-image or EFI iso from USB.
