Bare metal "server" - cleaning up after a program

[Juha Aaltonen]

I've been writing some kind of bare metal standalone gdb server/stub
that works through a serial line.

The problem is: when to clean up between debugged programs?
I have been wondering about the beginning of loading in a new program
("X0,0"-packet).
Maybe there is a better way/situation.

Gdb seems so focused to debugging processes running within an OS, that
"interpretation" in context of bare metal environment is hard.
