EDK2 UEFI firmware for Rockchip RK35xx platforms

WARNING: This repo is highly experimental

Description

This repository is based on the official open-source UEFI implementation from Rockchip, which is under active development.

Therefore, to keep up with the work from Rockchip, we should avoid modifying code from Rockchip in most cases.

Discussion thread: Windows / UEFI on Rock 5 (Mega thread)

Building

Using Arch Linux as example

Install required packages:

sudo pacman -Syu
sudo pacman -S git base-devel gcc dtc aarch64-linux-gnu-binutils aarch64-linux-gnu-gcc aarch64-linux-gnu-glibc python python-pyelftools iasl --needed

Required packages for Ubuntu/Debian:

sudo apt install git gcc g++ build-essential gcc-aarch64-linux-gnu iasl python3-pyelftools

Clone the repository:

git clone https://github.com/edk2-porting/edk2-rk35xx.git --recursive
cd edk2-rk35xx

Build UEFI (ROCK 5B for example):

./build.sh -d rock-5b

TODO

Create gpt image in build process instead of using the prebuilt one
Fix resetting to maskrom
