Getting packet (not package :-)) errors is normally fatal - it means your
downloaded program will have been corrupted.

Check the connections of your serial cable - does it work for other things?
For example, on the linux box, do:

cu -s 38400 -l /dev/ttyS0

or use "minicom" and type return a few times. You should see packets from
the remote GDB stub every time you do it, like:

$T0508:.....#ab

or similar.

Look at the PC target's screen - you should see the serial traffic being
displayed. If you don't, then it hasn't even got as far as that.
