Not with the ZedBoard but I do have experience with the Zynq. I know 
some people have worked with xmd and when I last talked to them about it 
xmd was fragile with gdb in the remote server mode.

What boot mode is the processor in ?

Have you generated a system from the hardware tools ?
Which version of the hardware and sdk tool are you using ?

I am currently using a hacked version of openocd. There is a patch in 
openocd gerrit related to nested ROM tables that is needed to get at the 
2 DAPs. I am using a flyswatter2 and a 20-to-14 pin adaptor avnet sell 
(at a price).
