Using the UART is as simple as it is in any other Linux distro - simply open /dev/ttyS0. If you don't know how, Google it - there are several Linux serial port how-to's that do a great job of describing it. The two wire ports, while I'm not sure exactly what byte order, format etc it's expecting things in, can be found at /dev/i2c-1. You should be able to access GPIO through devices in the /sys/class/gpio folder. Make sure you level shift from 1.8V logic - I've found Sparkfun's logic level converters to be invaluable for prototyping: http://www.sparkfun.com/commerce/product_info.php?products_id=8745 Hope this helps - I'm really not too much further than you are. While I'll second the lamentation that the documentation is virtually non-existent, I've used other Linux boards and the learning process is much the same. You have to expect this when diving into the embedded Linux world!
