What do I need?¶
- x86/x64 machine running any OS; at least 4G RAM, SSD, quad core (recommended),
- VirtualBox or similar virtualization software (highly recommended with a minimum of 25GB hard disk space for the virtual disk image),
- Setting up VirtualBox and compile environment is easy following our Vagrant tutorial,
- Docker environment is also supported for building kernels and full OS images,
- The officially supported compilation environment is Ubuntu Focal 20.04 x64 only! (Support for Ubuntu 18.04 will be there until either we run into issues we do not want to waste time on or upstream support ends),
binfmt_misckernel module. Some ubuntu-cloud images do not have this module. Switch to a generic kernel if that is the case.
- installed basic system, OpenSSH and Samba (optional),
- no spaces in full path to the build script location allowed,
- superuser rights (configured
sudoor root shell).
Please note that system requirements (both hardware and OS/software) may differ depending on the build environment (Vagrant, Docker, Virtualbox, native).
How to start?¶
Native and VirtualBox environments:¶
Login as root and run:
apt-get -y -qq install git git clone --depth 1 https://github.com/armbian/build cd build
Run the script
Make sure that full path to the build script does not contain spaces.
Providing build configuration¶
After the first run of
compile.sh a new configuration file
config-example.conf and symlink
config-default.conf will be created.
You may edit it to your needs or create different configuration files using it as a template.
Alternatively you can supply options as command line parameters to compile.sh. Example:
./compile.sh BOARD=cubietruck BRANCH=current KERNEL_ONLY=yes RELEASE=bionic
BUILD_ALL cannot be set to “yes” via command line parameter.
Base and descendant configuration¶
You can create one base configuration (
config-base.conf) and use this in descendant config (
config-dev.conf). Three parameters (BRANCH, RELEASE, COMPRESS_OUTPUTIMAGE) will be overwritten.
. ./config-base.conf BRANCH="dev" RELEASE="buster" COMPRESS_OUTPUTIMAGE="sha,gz"
Using our automated build system¶
If you do not own the proper equipment to build images on your own, you can make use of the automated build system. Packages are recompiled every night (starting at 00:01 CEST) and a few testing images are produced. These images are accessible on the download server under board folder, subfolder “Nightly”. Packages, when successfully built, are published in the beta repository. You can switch to beta repository in armbian-config or by changing apt.armbian.com to beta.armbian.com in /etc/apt/sources.list.d/armbian.list.
Board beta images are defined in board configuration files which are located here. This is a typical board configuration:
# A20 dual core 1Gb SoC BOARD_NAME="Banana Pi" LINUXFAMILY="sun7i" BOOTCONFIG="Bananapi_defconfig" MODULES="hci_uart gpio_sunxi rfcomm hidp sunxi-ir bonding spi_sun7i 8021q a20_tp #ap6211" MODULES_NEXT="brcmfmac bonding" # KERNEL_TARGET="legacy,current,dev" CLI_TARGET="buster,bionic,focal:current" DESKTOP_TARGET="stretch:legacy,current" CLI_BETA_TARGET="" DESKTOP_BETA_TARGET="" # BOARDRATING="" CHIP="http://docs.armbian.com/Hardware_Allwinner-A20/" HARDWARE="https://linux-sunxi.org/Banana_Pi" FORUMS="https://forum.armbian.com/forum/7-allwinner-a10a20/" BUY="http://amzn.to/2fToHjR"
You can find more information about those variables here.
If you want that our automated system start making images for this particular board, you need to alter parameters
Variants are depenendend from
KERNEL_TARGET definitions and supported userlands:
To edit those parameters you need to push changes to the build script.
You need to fork a project and create a pull request and after it is imported by one of the administrators, images will start to show up in appropriate folder.
If you want to enable Debian buster desktop image with current kernel choose the following:
or for command line interfaces Ubuntu Bionic based images with legacy kernel 4.19.x
or for image with latest upstream development kernel.
Using alternate armbian builder repos and branches¶
By default, armbian-builder assumes working from
https://github.com/armbian/build.git. If you are working from your own repo / branch,
touch .ignore_changes will cause armbian-builder to not attempt a repo checkout.
Executing any bash statement¶
Currently, invoking compile.sh will run a monotonous task of building all the components into a final image.
In some situation, especially when developing with Kernel or U-Boot, it is handy to run a portion of that great task like:
# using default profile ./compile.sh 'fetch_from_repo "$BOOTSOURCE" "$BOOTDIR" "$BOOTBRANCH" "yes"' ./compile.sh 'compile_uboot'
You can also dump the variable:
# using profile of `userpatches/config-my.conf` ./compile.sh my 'echo $SRC/cache/sources/$BOOTSOURCEDIR'
NOTE: please use single quotes to keep the
$VAR from early expansion in the command line shell.
