[microblaze-uclinux] debugging problems, resent from gmail

["Westover Scientific" <mlistwsi@xxxxxxxxx>]

When I run the microblaze-uclinux-gdb command it doesn't
bring the "debugger window" instead it remains at a command prompt. I
am trying to follow the instructions in "Debugging User Applications in
PetaLinux".

I did try running microblaze-uclinux-insight directly and I get a
message that it could not establish a connection to a remote target.

Suggestions?
