Arch Linux PKGBUILD for Linux kernel version 6.13 on the ClockworkPi uConsole (aarch64/arm64), based on the Raspberry Pi Linux kernel source tree, and PotatoMania's work on booting Arch Linux on the uConsole.

This repository contains the changes needed for the axp20x power and ocp8178_bl backlight drivers to build the 6.13 kernel (based off the patches included in PotatoMania's kernel 6.6 linux-uconsole-rpi64 package).

Built and testing on a CM4 uConsole, do not have CM3 or CM4S hardware for validation.

How to Build

This assumes you're building this on an x86_64 version of Arch Linux. If you're building this on an arm64 Arch Linux host, running makepkg should suffice.

Dependencies

pacman -S aarch64-linux-gnu-gcc aarch64-linux-gnu-binutils

Build Package

makepkg CARCH=aarch64 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-
