Make the entry point a breakpoint instruction, then in your .gdbinit 
script have:

define hook-stop
  if $pc == start
    si
  end
end

where 'start' is your application's entry point. Note, the 'si' 
instruction works on the Coldfire how-ever you may need something else 
such as 'set $pc = $pc + 2' to skip the breakpoint instruction.

You start gdb with the application's image.


ps: My Right Boot supports the '--debug' command line where it sets the 
breakpoint instruction for you. I always have a couple of nops at the 
start of my application.
