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) - The "kernel .id" column uses the linux kernel 2.6.35 naming convention to help user research and changes in linux source code.

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
