What this project does?
- Builds custom kernel, image or a distribution optimized for low resource HW such as single board computers,
- 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
- x64 or aarch64 machine with at least 2GB of memory and ~35GB of disk space for a virtual machine, container or bare metal installation,
- Ubuntu Jammy 22.04 x64 or aarch64 for native building or any Docker capable x64 / aarch64 Linux for containerised,
- Superuser rights (configured sudo or root access).
Simply start with the build script
apt-get -y install git
git clone https://github.com/armbian/build
cd build
./compile.sh
- Interactive graphical interface.
- The workspace will be prepared by installing the necessary dependencies and sources.
- It guides the entire process until a kernel package or ready-to-use image of the SD card is created.
Build parameter examples
Show work in progress areas in interactive mode:
./compile.sh EXPERT="yes"
Run build framework inside Docker container:
./compile.sh docker
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_ONLY=no \
KERNEL_CONFIGURE=no \
CARD_DEVICE="/dev/sda"
