Build Raspberry Pi 4 UEFI Firmware from source

Summary

This repository aims to generate more recent installable builds of the official EDK2 Raspberry Pi 4 UEFI firmware.

Please note that the success of the build is not guaranteed, as some submodules or submodule dependencies may fetch more recent code.

Initial Notice

PLEASE READ THE FOLLOWING:

• This firmware build does not provide WiFi and BT Raspberry Pi overlays, WiFi and BT is disabled in config-cm4.txt.

• Many drivers (GPIO, VPU, etc) are still likely to be missing from your OS, and will have to be provided by a third party. Please do not ask for them here, as they fall outside of the scope of this project.

• The following extra patch is applied:

  • RPi4_disable_3GB_RAM_limit.patch
  • RPi4_set_system_table_ACPI+DeviceTree_by_default.patch
  • RPi4_increase_SD_card_default_speed_to_50_83.patch
  • RPi4_decrease_default_CpuLowSpeedMHz_to_600.patch

Usage

cd RPi4
BRANCH_NAME="1.36-beta-update-20240224"
ARTIFACTS_DIR="RPi4_UEFI_${BRANCH_NAME}"
mkdir "release/${ARTIFACTS_DIR}"
chmod 777 -R "release/${ARTIFACTS_DIR}"

# Build
podman build --squash --build-arg BRANCH=${BRANCH_NAME} -t localhost/ndf-uefi-rpi4:latest .

# Copy artifacts to attached volume dir
podman run --rm -it -v $PWD/release/${ARTIFACTS_DIR}:/artifacts:Z localhost/ndf-uefi-rpi4:latest

# Fix artifact permissions
sudo find "release/${ARTIFACTS_DIR}" -type d -exec chmod 750 {} +
sudo find "release/${ARTIFACTS_DIR}" -type f -exec chmod 640 {} +
sudo chown -R ${USER}:${USER} "release/${ARTIFACTS_DIR}"
cd "release/${ARTIFACTS_DIR}/artifacts" && ls -la
