Subject: Connect to already running target?
Date: Wed, 11 Jun 2003 03:26:00 -0000	[thread overview]
Message-ID: <3EE63EEB.4136.18FFA12@localhost> (raw)

Is it possible to connect to an already running remote target with 
"target remote" and/or "target async"?

As of GDB 5.0, the answer appears to be no, unless I've just not hit 
on the right incantation.  If the initial '?' packet gets a 'T' 
response, of course GDB assumes the target is stopped.  If it gets an 
"O" response (which the docs seem to suggest should work), it treats 
it as a fatal packet error and a failed connection.  If it gets an 
empty reply, it reports a packet error but then appears to be waiting 
for the target to stop (or just a further reply).  But trying to 
interrupt the target with ctrl-C doesn't work - the ctrl-C packet is 
apparently not sent.  Same result if it gets *no* reply, but without 
the packet error mesage.

I searched the list archive, but all I came up with is a post from 
Andrew dated August 2002 RE dropping "target cisco" support, where he 
mentioned that the cisco target supported connecting to a running 
target and this should be integrated into the standard remote 
targets.  Has that happened yet?
