I have been using Angstrom for a little while now, and now am attempting to 
install Ubuntu 13.10 on my BeagleBoard-xM using the following procedure:

http://elinux.org/BeagleBoardUbuntu#Method_2:_Use_the_NetInstall_method


I setup the boot partition on my SD card without any issues using the 
following command from the netinstall git repository mentioned above:

$ sudo ./mk_mmc.sh --mmc /dev/sdf --dtb omap3-beagle-xm --distro saucy 
--serial-mode


I have tried toggling the console parameter between ttyO2 and ttyS2 with no 
luck.  I get the following initial output from U-Boot:

At this point, I get no additional output on the serial device.  I also 
reformatted the MMC without the --serial-mode parameter, hooking up my DVI 
monitor.  I get a yellow/orange screen during U-Boot initialization, and 
then I get no display.  Does anyone have any advice?

Thanks!
