Table of contents

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

Basic requirements

  • x86_64 or aarch64 machine with at least 2GB of memory and ~35GB of disk space for a virtual machine, WSL2, container or bare metal installation
  • Ubuntu Jammy 22.04.x amd64 or aarch64 for native building or any Docker capable amd64 / aarch64 Linux for containerised
  • Superuser rights (configured sudo or root access).
  • Make sure all your system components are up-to-date. Outdated Docker binaries, for example, can cause trouble.

Start with the build script

apt-get -y install git
git clone --depth=1 --branch=main 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 Focal image for Orangepi Zero. Use modern kernel and write image to the SD card:

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