AOSP for wandboard dual

Hi Robert,

I want to practice in Android to use HDMI touch display,USB(both Host and OTG),Gigabit LAN,Serial port, Wifi, bluetooth and Audio.
Please guide me to make work at-least up to serial port from the start of the list.

Android Apps I shall try to configure and cook that, provided in AOSP.
I find difficult to configure or modify architecture and board specific items needed for wandboard in kernel and Uboot.

Thanks.
