- builds custom Debian based Linux system optimized 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 ~35GB of disk space for the VM, container or native OS,
- Ubuntu Focal 20.04 x64 for native building or any Docker capable x64 Linux for containerised,
- superuser rights (configured sudo or root access).
apt-get -y install git
git clone https://github.com/armbian/build
cd build
./compile.sh
- The script will take care about preparing the workspace like installing necessary dependencies and downloading sources and tools.
- It guides through the process until either a kernel package set or a readyo-to-image for a sdcard is created.
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" 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 and documentation, 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.
