Hello£¡
	My current plan is to port gdb to a 8-bit embedded processor with a new,instead of directly communicating with the processor,our gdb will communicate with an emulator.Now suppose the BFD has been successfully ported,I am still wondering about what in detail I need to do with the remote debugging part.In some documents,I have seen some ones 
say it is a must to implement the GDB RSP(remote serial protocol),so how in detail I can do to implement it,which files of what functionality I must create or modify?  Waiting for help! Thanks!

We do the same here and use a "proxy" GDBInterface which can communicate
with the
simulator (via pipes) or with the hardware (via COM port).

It's just like porting to a new arch, only the "child_create_inferior"
function either
launches the simulator or opens a connection to the hardware.
(Note that we're using a old gdb, things might be different in newer
versions)

HTH.

Bye.
