This one is easy: the load command loads an executable file in the memory of
a remote target, connected via serial port or ethernet to the host where
you are running gdb.

To debug programs on boards and things of a sort one needs a cross debugger.
You need gdb built for your target and the target must have a gdb stub so it
can talk to gdb.


I don't remember when the other one is issued but, judging by the second one, 
it seems that you are not using gdb properly. I would recommend a second pass
through the manual.  If you still have problems after that let us know.

It means his target isn't defining to_has_exec in the target_ops.
So it doesn't know how to run it.
When I first started the port to BeOS, after I got the config files
set up right so that you could actually compile, these are the
messages you would get if you tried to load and run something.
