If you are using Insight 5.0 then please update to a CVS snapshot. 5.0 has 
known instabilities running with Angel. Or you can update your embedded 
system with GDB stubs/RedBoot instead.

If neither of these are possible then ensure that you are running your 
serial connection at 9600 and use console-mode gdb, gdb -nw (this is the 
most stable it's going to get, but it's still very fragile).

The GDB stub is the embedded-system-side back-end that Insight talks to. At 
the moment you are using Angel as your back-end.
