If you've got sufficient logic resources I stronly recommend using the 
mdm/fsl stuff - it makes makes the build-download-debug cycle much 
faster than using the serial port.  Also, since it's hardware based, 
it's less intrusive than having the xmdstub program running on microblaze.

It seems a bit stragne - what happens if you quit xmd after the 
download, then restart/reconnect, *then* do the con 0X80000000?

That's pretty odd - those are the first instructions in the early kernel 
startup code.  I can't imagine why you'd be getting a breakpoint in 
there.  If you can, try to go with the mdm debugging, it seems much more 
robust.
