[ECOS] debugging with gdb

I have an A&MViper powerpc860 board up and running. I am currently 
investigating debugging options. The board has redboot on it with gdb stubs.

If I configure ecos not to have a network stack then I can connect to 
the board with gdb over the network and download, run and debug my test 
app. If I build ecos with network support it doesn't work as when the 
code is run it initialises the network which obviously resets the 
connection to gdb.

Is there a way to prevent this from happening? I assume not. I could 
presumably do the same but use the serial port although I don't want to 
do it as it will be slow and I need the serial port for other things.

So I was looking at debugging with a BDM. There don't sem to be many 
docs on doing this, does anyone know of any good resources? What BDM 
device would anyone recommend and are there any reference gdbinit 
scripts for setting up powerpc/860?

Many thanks,

Will Wagner
