Panel/Display works. Broadcom wifi works. System boots. All other features untested.

== Kernel ==
The device tree patches to make the panel/display work are currently only available as kernel patches. The official patches only support kernel 5.x, however there is a community patchset for kernel 6.5 available at [[https://github.com/Autianic/clockworkpi-linux-kernel/tree/master/linux-clockworkpi-a06]]

These patches can be applied using the following nix snippet:
```
boot.kernelPackages = pkgs.linuxPackages_6_5;
boot.kernelPatches = [
{
name = "suspend";
patch = fetchurl { url = https://raw.githubusercontent.com/Autianic/clockworkpi-linux-kernel/master/linux-clockworkpi-a06/00-rockchip-suspend.patch };
}
{
name = "a06";
patch = fetchurl { url = https://raw.githubusercontent.com/Autianic/clockworkpi-linux-kernel/master/linux-clockworkpi-a06/01-clockworkpi-dts-a06.patch; };
}
{
name = "backlight";
patch = fetchurl { url = https://raw.githubusercontent.com/Autianic/clockworkpi-linux-kernel/master/linux-clockworkpi-a06/02-backlight-ocp8178.patch; };
}
{
name = "cwd686";
patch = fetchurl { url = https://raw.githubusercontent.com/Autianic/clockworkpi-linux-kernel/master/linux-clockworkpi-a06/02-panel-cwd686-driver.patch; };
}
{
name = "cwu50";
patch = fetchurl { url = https://raw.githubusercontent.com/Autianic/clockworkpi-linux-kernel/master/linux-clockworkpi-a06/02-panel-cwu50-driver.patch; };

}
];
```

=== Bootloader ===
At present I am not sure where the bootloader images used by the official/vendor supplied distro can be obtained. The easiest way to make any generated image bootable is to copy them from the official image available here: [[http://dl.clockworkpi.com/uConsole_A06_v1.1e.img.7z]]

```
$ sfdisk --dump uConsole_A06_v1.1e.img
<...>
uConsoleA06_v1.1e.img1 : start = 32768, size = 14942208, type=83

$ sfdisk --dump your_nixos_image.img
<...>
your_nixos_image.img1 : start = 16384, size = 61440, type = b
your_nixos_image.img2 : start = 77824, size = 15322384, type = 83, bootable

$ dd if=uConsole_A06_v1.1e.img of=nixos_a06.img count=32768
$ dd if=your_nixos_image.img skip=32768 of=nixos_a06.img seek=77824
```

The partition table for the resulting image will then be wrong, but we can fix that with fdisk by deleting our partition, and then recreating it.
```
fdisk ./nixos_a06.img
