Hi Marco --

As you already know, Xilinx maintains a separate repository
with the Linux versions of MicroBlaze gdb and other tools.
You can find info here:  http://xilinx.wikidot.com
These are older versions and have not been updated to the
current GNU versions.

The tools for MicroBlaze in the GNU tree only support standalone
embedded systems.  Gdb has only been tested with Xilinx's
JTAG connection to the target using XMD.

Support for Linux on MicroBlaze in the GNU tree is essentially
the same as in the older versions, which, as you have noted,
has not been ported to work with the current version of gdb &
gdbserver.  I don't have a suitable environment to run Linux on
MicroBlaze, so I cannot address any of these issues.

> So do you have any hints for me how to proceed to get a new GDB + gdbserver up?

I understand that Xilinx is interested in upgrading the
Linux tool chain to the same version in the GNU tree and
presumably submitting any changes to FSF.  I don't have
any details on the when this might happen; the status on
this has not changed in many months.  Naturally, updating the
GNU tree gdb and gdbserver to work on correctly on MicroBlaze
Linux doesn't require Xilinx's involvement, the projects are
open source.  It does require a suitable environment and
someone to do the port.

Sorry I can't be more help.
