Building image

There is great Armbian documentation here.

  • Clone repository
 # git clone https://github.com/armbian/build.git

Soon (probably) there will be olimex fork with some customizations.

  • Run builder
 # cd build
 # ./compile

Building requires root access. System preparation can take long, depending on system, etc. After that you should see something like that:


Select Full OS Image for flashing. This will create output image for direct flashing on SD-card.


Select Do not change the kernel configuration. All needed configuration should be selected automatically. If you want some kernel modifications, select the other option.


Go to <Show CSC/WIP/ESO>. Currently A20-SOM204 is not officially supported by Armbian team. Instead the board is supported by Olimex team, which is under CSC section. So select that menu and confirm the action.

Select olimex-som204-a20.


Select desired distribution. We recommend jessie for server build, and xenial for image with desktop environment.


Select if you want server or desktop.

After build the images and other packages will be in the output folder:

  • Flashing image

Put sdcard in the host PC. New device should appear, e.g. /dev/sdc. Flash the image using the following command:

 # dd if=Armbian_5.41_Olimex-som204-a20_Debian_jessie_dev_4.15.0.img of=/dev/sdx bs=10M

Replace /dev/sdx with your device. You must use /dev/sdx, not /dev/sdx1!
