WIP stuff to get started on the pinebook pro.
|
|
|
|
## Using in your configuration
|
|
|
|
Clone this repository somwhere, and in your configuration.nix
|
|
|
|
```
|
|
{
|
|
imports = [
|
|
.../pinebook-pro/pinebook_pro.nix
|
|
];
|
|
}
|
|
```
|
|
|
|
That entry point will try to stay unopinionated, while maximizing the hardware
|
|
compatibility.
|
|
|
|
|
|
## Current state
|
|
|
|
*A whole lot of untested*.
|
|
|
|
You can look at the previous state to see that the basic stuff works. But I
|
|
find listing everything as working is hard.
|
|
|
|
What's untested and not working will be listed here at some point. Maybe.
|
|
|
|
### Known issues
|
|
|
|
#### `rockchipdrm` and `efifb`
|
|
|
|
This can be worked around by booting with the `efifb=off` kernel command-line.
|
|
|
|
This is already handled for you by this configuration. If using the generic
|
|
UEFI AArch64 iso, you will need to add the option yourself to the command-line
|
|
using GRUB.
|
|
|
|
#### *EFI* and poweroff
|
|
|
|
When booted using EFI, the system will not power off. It will stay seemingly
|
|
stuck with the LED and display turned off.
|
|
|
|
A [workaround exists](https://github.com/Tow-Boot/Tow-Boot/commit/818cae1b84a7702f2a509927f2819900c2881979#diff-20f50d9d8d5d6c059b87ad66fbc5df26d9fc46251763547ca9bdcc75564a4368),
|
|
and is built in recent Tow-Boot (make sure your release is 2021.10-004 or more recent).
|
|
|
|
|
|
## *Platform Firmware*
|
|
|
|
> **NOTE**: The previously available customized *U-Boot* from this repository
|
|
> are not available anymore.
|
|
|
|
### *Tow-Boot*
|
|
|
|
I highly suggest installing *Tow-Boot* to the SPI Flash.
|
|
|
|
- https://github.com/Tow-Boot/Tow-Boot
|
|
|
|
Having the firmware installed to SPI makes the device act basically like a
|
|
normal computer. No need for weird incantations to setup the platform boot
|
|
firmware.
|
|
|
|
Alternatively, starting from the *Tow-Boot* disk image on eMMC is easier to
|
|
deal with and understand than having to deal with *U-Boot* manually.
|
|
|
|
|
|
### Mainline *U-Boot*
|
|
|
|
Mainline U-Boot has full support for graphics since 2021.04. The current
|
|
unstable relases of Nixpkgs are at 2021.04 at least.
|
|
|
|
```
|
|
$ nix-build -A pkgs.ubootPinebookPro
|
|
```
|
|
|
|
Note that the default U-Boot build does not do anything with LED on startup.
|
|
|
|
|
|
## Keyboard firmware
|
|
|
|
> **WARNING**: Some hardware batches for the Pinebook Pro ship with the
|
|
> wrong chip for the keyboard controller. While it will work with the
|
|
> firmware it ships with, it *may brick* while flashing the updated
|
|
> firmware. [See this comment on the firmware repository](https://github.com/jackhumbert/pinebook-pro-keyboard-updater/issues/33#issuecomment-850889285).
|
|
>
|
|
> It is unclear how to identify said hardware from a running system.
|
|
|
|
To determine which keyboard controller you have, you will need to disassemble
|
|
the Pinebook Pro as per [the Pine64
|
|
wiki](https://wiki.pine64.org/wiki/Pinebook_Pro#Keyboard), and make sure that
|
|
the IC next to the U23 marking on the main board is an **SH68F83**.
|
|
|
|
```
|
|
$ nix-build -A pkgs.pinebookpro-keyboard-updater
|
|
$ sudo ./result/bin/updater step-1 <iso|ansi>
|
|
$ sudo poweroff
|
|
# ...
|
|
$ sudo ./result/bin/updater step-2 <iso|ansi>
|
|
$ sudo poweroff
|
|
# ...
|
|
$ sudo ./result/bin/updater flash-kb-revised <iso|ansi>
|
|
```
|
|
|
|
Note: poweroff must be used, reboot does not turn the hardware "off" enough.
