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!

Debugging

Enabling DRM debug output

The DRM driver supports multiple debugging levels.

Add the following in /boot/armbianEnv.txt:

extraargs=drm.debug=0xf

-==Changing display output==
-With current kernel version (4.13) changing display output must be done by recompiling u-boot. This is necessary because kernel supports only SimpleFB. This will change in the future.
-===LCD===
-====Enable touchscreen====
-Create blacklist file:
- # echo "blacklist sun4i_gpadc_iio" > /etc/modprobe.d/blacklist-touchscreen.conf
- # echo "blacklist sun4i_gpadc" >> /etc/modprobe.d/blacklist-touchscreen.conf
-====Calibrate touchscreen====
-Install calibration package:
- # apt-get install xinput-calibrator
-After completion start the program inside the X.
- Applications
-   -> System
-     -> Calibrate Touchscreen
-You will see blank screen. Touch the display at the marks. Then store the calibration values.
-Create new file '''99-calibration.conf'''
- # cat > /etc/X11/xorg.conf.d/99-calibration.conf << __EOF__
- Section "InputClass"
- 	Identifier	"calibration"
- 	MatchProduct	"1c25000.rtp"
- 	Option	"Calibration"	"3930 108 348 3948"
- 	Option	"SwapAxes"	"0"
- EndSection
- __EOF__
-Put the values from the calibrator program.
-===VGA===
-====Changing resolution====
-The default resolution in 1024x768. You can list all resolutions with:
- # xrandr
-The output should be something like this:
- Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 8192 x 8192
- VGA-1 unknown connection 1280x1024+0+0 (normal left inverted right x axis y axis) 0mm x 0mm

-x480       60.00
-x480       59.94
-To change resolution from the command line, do the following:
- # export DISPLAY=:0
- # xrandr -s <resolution>
-===HDMI===
-====Set custom resolution====
-To use lower resolution than 1920x1080 append '''/boot/armbianEnv.txt''' with:
- extraargs=video=HDMI-A-1:1280x1080
-This will set monitor with 1280x1080 resolution. Getting supported modes is done with:
- # cat /sys/class/drm/card0-HDMI-A-1/modes
