I'm curious about this problem - I haven't heard of any issues, and am 
regularly building this here without problems.

Can you provide some more info (ie exact EDK/ISE versions), and error 
messages, logs etc?

In the /code subdir of the mbvanilla project there are a few old test 
programs.  In fact, even the bootloader program should load and run, 
display the menu etc etc. There are some functions in there to do memory 
tests etc, you could enable them as well.

By default the bootloader will link to execute from BRAM, however 
there's no reason you can't pass the START_ADDRESS parameter to mb-gcc 
to link it up at 0x80000000, then upload it to DDR via xmd.

Just to confirm, are you able to connect to the platform if you build it 
in xmdstub mode?
