Well, when I added it (manually, it wouldn't work with the graphical 
configuration tool), I got a new package "Cirrus Logic ethernet driver", 
description "Ethernet driver for Cirrus EDB7xxx development boards".

Well, it is my experience in general. When I was trying to get a working 
set of ARM tools to compile eCos, I tried getting all the latest - gcc as 
well as eCos - and failed miserably with all sorts of errors I didn't have 
time to analyze. I prefer to wait for someone to archive up his working 
source tree, call it a snapshot, and make it available for download. It 
also means I don't have to wrestle with the cvs client program.

The eCos version I'm running brings up the board OK, and that's good enough 
for the working demo I need to show next week. I've been working on 
optimizing my DOS and ISO9660 filesystems, and porting my JPEG and MPEG-1 
decoders, and that has kept me happily occupied.

The product I'm working on right now is the low-end version that doesn't 
use networking, so I don't see any reason to try to jump through blazing 
hoops to get the latest greatest eCos version downloaded and working. It 
will probably go to manufacturing with 1.3.1 in it.

The higher-end versions with Ethernet.. well, I'll cross that bridge when I 
come to it.
