AM3352-SOM user's manual
For example, to set LCD video otuput suitable for 7 inch display (800x480) write:
sudo ./change_display_am3352.sh -l -800x480
At this point you would be asked if you wish to reboot the board. The video output changes would
be applied after a reboot, so it is advised to reboot the board at this point.
The usage f the script is shown in the picture below:
In case you need a custom video output resolution you would need to edit the kernel. There are no
configuration files that can be easily edited to achieve the desired video output.
3.8 Connecting and calibrating a display
One of the ways to interact with the board is via an external display (with or without touchscreen
component). However, there is only a 40-pin female connector AM_CON-LCD with a 0.05'' step.
Unlike other OLIMEX Linux-enabled boards, the AM3352-SOM lacks a row of pins that allows the
user to connect a display out-of-the-box. The board's AM_CON-LCD connector is female and has a
smaller 0.05'' step (note that if you are using AM3352-SOM mounted on AM3352-SOM-EVB a
0.01'' LCD connector would be available). This means that if you use a stand-alone AM3352-SOM
for LCD output and a display made by OLIMEX, you would need additional 2×20 MALE-MALE
0.05'' header to convert the female connector to male. The 0.05'' headers are somehow hard to find
so we sell them here:

connectors. You would also need a compatible cable between the
board and the display. The current generation of OLIMEX-made displays have both 0.1'' and 0.05''
step connectors. The cable used for connection depends on the specific board you are using and
