RE: [ECOS] i386 platform !

[Sean Christensen <seanc at internap dot com>]

Hello,

Just sending a note about a similar (maybe) issue.  I have not had the
time to track it down, however I sent a note about it for a different
platform:

http://sources.redhat.com/ml/ecos-discuss/2004-10/msg00435.html

My eCos sources are only a few weeks old, too.  I do remember having
network based debugging working about a year ago.  I have just lately
needed to get it going again.  I figured that I had a config issue.

I will try to spend some more time on why my Redboot (gdb load) fails
over the network connection...
