Hello all, I'm posting once again as I havn't got any reply, but this time will give some more details about same two problems I have - 1) for each new gdb session, start - connect - dissconnect - close Hyperteminal, then only gdb connects to target, why this is so? 2)My host machine (running gdb) suddenly restarts...? I am using prolific USB to Serial Bridge cable for communication. USB end of that cable connects to host and Serial end to target. Will this cable cause host to restart...? I am srongly facing these two problems at every gdb session which are slowing down my main activity of writing a stub. So this time I'm greatly hoping for at least a single reply from the list. Anyone, though don't have solution for this, could at least suggest me what may be the cause of any of the problems.... Is there Nobody...? I realy hope for somebody. Thanks and Regards, medake Note: forwarded message attached. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
