APF28Dev

Description

This is the Armadeus System's standard development board/baseboard for the APF28 module.

Extension connectors

Default (in bold) pin usage on the extension connectors J9 and J10 - Each functionality can be disabled by simply using "make linux-menuconfig" (implementation on-going)

Selecting LCD

Two LCD are available for the apf28Dev kit. By default, TM035KBH02 is selected in Linux. To use the LW700, under U-Boot do :

BIOS> setenv console ${console} lcd_panel=LW700
## Switch baudrate to 115200 bps andpress ENTER ...
BIOS> saveenv
