to set up the pin muxes correctly, and I attached my serial device (a sparkfun razor 9dof imu, a 3.3v device) to the rx/tx pins, and I am not getting anything on ttyO1 or ttyO2 (I tried both UART1 and UART2)
to confirm that the serial device was working and I had the baud set right etc I connected the rx/tx on the serial device to a sparkfun FTDI basic and plugged that into the USB port of the beagle. I was able to connect to ttyUSB0 and it worked well... so something is wrong with my UART setup.
Is it possible that you switched RX and TX going into your Beagle's
UART? I know it is a silly suggestion -- but I just spent an hour a
few days ago trying to get that right for hooking up a bluetooth board
on an arduino, and I don't see it mentioned explicitly here.

nubey question here, but can anyone point me to get started with installing linux on raspberry pi, and some other programming tutorials of raspberry pi?
I followed this guide: http://elinux.org/RPi_Easy_SD_Card_Setup - just
downloaded the image, wrote it to an SD card, put it in the RPi and it
booted into linux.
