problems using arm multi-ice

[andy parker <andy dot parker at oxsemi dot com>]

Hi folks,

I'm trying to debug an embedded arm target using a multi-ice module but 
I am experiencing some technical difficulties. I've built the multi-ice 
server as detailed in on http://sources.redhat.com/ecos/multi-ice.html
and I'm running gdb built for arm-elf target on a cygwin host. When I 
load a test image, I observe lots of 'ignoring packet errors' messages 
in the gdb shell and eventually the gdb session appears to hang. I've 
also run the mult-ice server in debug mode and observed some output, but 
I don't really know what (if anything) is significant. My target 
software is OS-less and was built using gcc 3.1.1. Apologies in advance 
if I've left out any important details, but I'd appreciate any help to 
getting up and running. Output from gdb and the muti-ice is given below.

Cheers,
Andy
