A20-OLinuXino-MICRO user's manual
users, we have provided a shell script that can be executed in order to set preferred video
output and resolution.
For Android that you boot from the NAND memory you would need an image suitable for the
specific resolution. Download locations to such images might be found at the wiki article for the
A20 board here:
https://www.olimex.com/wiki/A20-OlinuXino-MICRO
.
For Linux Debian you would need to execute a shell script to be able to change the resolution. It is
very good idea to use a serial cable for connection to the board from a personal computer since in
this case you are dependent on a video resolution (a cable like USB-SERIAL-CABLE-F). When the
board boots type:
./change_display*
or
./change_display_A20_OLinuXino.sh
and choose the resolution and the interface (LCD, HDMI or VGA).
The supported resolutions are:
For LCD:
1. 4.3" (480×272)
2. 7" (800×480)
3. 10" (1024×600)
For HDMI:
0. 480i
1. 576i
2. 480p
3. 576p
4. 720p50
5. 720p60
6. 1080i50
7. 1080i60
8. 1080p24
9. 1080p50
10. 1080p60
For VGA: (note that the VGA signals are routed to custom 6 pin connector and you need to from
adapter to standard VGA connector, Olimex also sells such adapter cables)
