gdb frame

[Vineet Sharma, Noida]

Hi All,
         To make my understanding clear about the working of gdb. I have the
following question :


Q1 : If my simulator has its memory "Buff[MAX_MEMORY]" and its own stack and
frames in some part of this Buff.
     Now how is the gdb stack and frames different from the stak and frames
in my simulator(memory), are they same?
     If different whats the logic? and how does it functions?


     If both are same how do we relate each other ?



Q2 : I want to execute hex file , but i have symbols in a coff file , so
does the command 

	(gdb) target sim
	(gdb) symbol-file XXX.out
	(gdb) load XXX.hex
	(gdb) run


	Are these command ok?

Regards
Vineet
