Ok,

I've managed to make it running using the gdb command line.

As far as I understood, the (pretty good) documentation is fine using an application compiled with no optimisation which is not the default case in petalinux template.

If you are trying to run gdb to debug a user application running on your
microblaze platform then you should be using the microblaze-uclinux-gdb

Have a look at the following documentation.  I have tested it on 2.6 so
it should work.

http://developer.petealogix.com/wiki/UserGuide/Debugging/UserApplications

Note that there are some error with the documentation that it refers to
'mb-uclinux-gdb'  this should be 'microblaze-uclinux-gdb'

Cheers,
B.
