Using GDB on VME

[cperkon@fh-landshut.de]

Hi,

I'm like to use the gdb to debug a Motorola ColdFire CPU as target. 
My host system is Sun SPARC (Solaris 8). The connection between the host
an the target is a VME-Bus.

My problem on this constellation is, that I do not know how to tell GDB
to connect to my target. I didn't find any informations about how to
configure GDB on a target connected else then a serial cable. 
All the papers I found in the net discusses the possbilty of debugging
remote systems on serial cables. I'm agree with the necessity to have a
stub on a target system, which is not configured for communications with
the host.
In my case the target and the host are conncted permanently. (And they
twaddle a lot... :) )
So I've a established connection I'd like to use for my debugging
project  - and I wonder if I could not use it.
The only thing I need sounds so simple: I just need to connect the gdb
to the VME-device driver. But I don`t know how. 

Can anybody give me an idea how to solve the problem?

May be anybody is experienced in debugging accross a VME-Bus (using gdb)
?

Thanks for any help.
