What this project does?
- 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.
What do you need to get started?
- x64 machine with at least 2GB of memory and ~35GB 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).
How to build an image or a kernel?
apt-get -y install git
git clone https://github.com/armbian/build
cd build
./compile.sh
Build parameter examples
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?
Compare with industry standards
Check similarity, advantages and disadvantages compared with leading industry standard build software.
