I have the other machine set up with comconsole,
and in fact I have booted with -g and
am sitting in what I assume is the debugger....
If I hit CR I get a string that looks like:
$T0508:7ddf1af0;05:70ef1df0;04:68ef1df0;#97
I'm guessing the gdb stub is responding to me somehow with this..
I can't however find any info on how to START debugging
with gdb...
how can I get gdb to start talking to the stub?
Of course it's not helped by teh fact that as a port all teh docs are
shadowed by the ones form the original gdb :) very cfusing if you
forget to prefix everything with /usr/local...
If you can point ou twhich parts of the docs are the most useful for
this I'd be grateful
as I'm drowning is irrellevant information..

p.s.
in an attempt to get some response I typed....
(gdb) run
Starting program:

target_resume (-1, continue, 0)
/usr/home/julian/build/FreeBSD-2.2A/usr/src/sys/compile/IAF/kernel: Exec

Eh? whadyamean "Wrong architecture?"
target_wait (-1, status) = 10403, status->kind = exited, status = 1
target_terminal_ours ()
Program exited with code 01.
target_mourn_inferior ()
You can't do that without a process to debug
