A20-OLinuXino-LIME2 user's manual
online as "RNDIS driver" (Remote Network Driver Interface Specification). The drivers are provided by
Microsoft and they should be available for every Windows distribution – refer to the respective files and
articles provided by Microsoft on how to install the required drivers.
2.5.5 SSH via Ethernet connector
SSH protocol allows you to login remotely to the command-line interface of the A20-OLinuXino-LIME
board. You would need an active Ethernet connection to the board.
The newest images have a configuration that allows SSH via the Ethernet connector. The static IP address
to access the board is 192.168.1.254
2.6 Changing the default video output resolution
Depending on the display or the screen you want to use with the A20-OLinuXino-LIME2, you might need
to apply software changes to the prebuilt Android or Linux image. The typical OLinuXino user would not
need to edit the files, however.
To ease the process of changing the resolution we have compiled a number of Android images for the
Android users (with hard-coded video output settings). Alternatively, for Debian Linux 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:

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_olimex.sh
It looks like this:
Then the main menu of the video configuration script shows up and you can select the desired interface
(LCD, HDMI or VGA):
