- builds custom Debian based Linux system optimised for supported single board computers,
- covers root filesystem generation, kernel image compilation and bootloader compilation,
- maintains low-level control software for a selection of hardware,
- provides a consistent user experience by keeping system standards across different SBC platforms.
- x64 machine with at least 2GB of memory and ~30GB of disk space for the VM, container or native OS,
- Ubuntu Bionic 18.04 / Focal 20.04 x64 for native building or any Docker capable x64 Linux for containerised,
- superuser rights (configured sudo or root access).
apt -y install git
git clone https://github.com/armbian/build
cd build
./compile.sh
Show work in progress areas in interactive mode:
./compile.sh EXPERT="yes"
Run build tools inside Docker container:
./compile.sh docker
Build minimal CLI Debian buster based image for Odroid XU4. Use modern kernel and write image to the SD card:
./compile.sh BOARD="odroidxu4" BRANCH="current" RELEASE="buster" CARD_DEVICE="/dev/sda" \
KERNEL_ONLY="no" KERNEL_CONFIGURE="no" INSTALL_HEADERS="yes" BUILD_DESKTOP="no" BUILD_MINIMAL="yes"
Build parameters, advanced build options, user defined configuration, build with Docker?
Check similarity, advantages and disadvantages compared with leading industry standard build software.

-
Have you found a bug in the build tools?
Try to recreate it with a clean build tools clone. Then search for existing and closed issues. If you don't find it there, open a new issue.
-
Do you have troubles elsewhere?
Armbian is free software and provides best effort help through community forums. If you can't find answer there and/or with help of general project search engine, consider hiring an expert.
-
Personalised support?
It is limited to active project supporters and sponsors. The shortest way to become one and receive our attention is a four figure donation to our non-profit project.
-
Adding a new feature?
You are welcome to suggest or contribute directly to the code with a pull request. In case your proposed changes are large, remember to discuss them prior to development.
-
Join development?
Join regulars on their active missions, start maintaining any part of the code: patches, drivers or scripted applications like armbian-config, address community wishes,
-
Help elsewhere?
Maintain and develop documentation, CI, autotests, seed torrents, help on forum moderating, project administration, costs.
- Participate in Armbian forums,
- Chat with fellow users on IRC #armbian on Freenode,
- Follow @armbian on Twitter or LinkedIN.
- Current and past contributors, our families and friends,
- Support staff that keeps forums usable,
- Individuals that help with their ideas, reports and donations.
Most of the project is sponsored with a work done by volunteer collaborators, while some part of the project costs are being covered by the industry. We would not be able to get this far without their help.
