Description

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

Errata

Extension connectors

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

Temporary fixes

Backlight

  • Force backlight to ON state:
echo 124 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio124/direction
echo 1 > /sys/class/gpio/gpio124/value

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
