It looks like XMD is not properly connecting to the microblaze.

Instead of using the dl.sh script, try doing it manually, to see what
part of the process is failing.  Here are the commands you need
(remember to remove/rename any file called xmd.ini from the project
directory, it contains default XMD commands, which you don't want right
now).

xmd

% xload mhs system.mhs
% connect mb mdm
% dow -data /path/to/image.bin 0xdeadbeef
% con 0xdeadbeef

(replace 0xdeadbeef with the start addres of your DDR/external memory)

error messages at any stage in this process should alert you to where
the problem is.

You don't need a bootlaoder when doing a JTAG boot like this.

Regards,

John
