Building image
Make sure to take a look at the official Armbian documentation here: https://docs.armbian.com
- Clone repository
# git clone https://github.com/armbian/build.git Cloning into 'build'... remote: Counting objects: 32391, done. remote: Compressing objects: 100% (69/69), done. remote: Total 32391 (delta 60), reused 75 (delta 44), pack-reused 32278 Receiving objects: 100% (32391/32391), 258.91 MiB | 959.00 KiB/s, done.

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!
