Armbian Linux Build Framework

What does this project do?

Builds custom kernel, image or a distribution optimized for low-resource hardware,
Include filesystem generation, low-level control software, kernel image and bootloader compilation,
Provides a consistent user experience by keeping system standards across different platforms.

Getting started

Requirements

x86_64 / aarch64 machine
at least 2GB of memory and ~35GB of disk space for VM, container or bare metal installation
Ubuntu Jammy 22.04.x for native building or any Docker capable Linux for containerised
Windows 10/11 with WSL2 subsystem running Ubuntu Jammy 22.04.x
Superuser rights (configured sudo or root access).
Make sure your system is up-to-date! Outdated Docker binaries, for example, can cause trouble.

Start with the build script

Development branch:

apt-get -y install git
git clone --depth=1 --branch=main https://github.com/armbian/build
cd build
./compile.sh

Stable branch:

apt-get -y install git
git clone --depth=1 --branch=v23.11 https://github.com/armbian/build
cd build
./compile.sh

Interactive graphical interface.
Prepares the workspace by installing the necessary dependencies and sources.
It guides the entire process and creates a kernel package or a ready-to-use SD card image.

Build parameter examples

Show work-in-progress areas in interactive mode:

./compile.sh EXPERT="yes"

Build minimal CLI Armbian Jammy for Raspberry Pi 4B with LTS kernel and write image directly to the SD card:

./compile.sh \
BOARD=rpi4b \
BRANCH=current \
RELEASE=jammy \
BUILD_MINIMAL=yes \
BUILD_DESKTOP=no \
KERNEL_CONFIGURE=no \
CARD_DEVICE="/dev/sdX"
