You can write a gdbserver-like part  in your simulator. Then communicate
 with GDB using TCP, UART or other way.

I don't know if it is possible. From my point of view, maybe it is harder
 than writing a gdbserver. Because GDB's build-in simulator is possibly
working in totally different way with your simulator. You should change
yours to meet its demands. Writing a gdbserver is only adding something,
it can work well with different version of GDB.

thanx for your reply...
Does any exist "gdbserver-like" template can let me do this job?
or, where do I find those files?

Dave,

Actually it is very easy to write. It uses RSP protocol to communicate
with GDB, more like a RSP packet translator. It understands RSP
packets that GDB sends to it, then acts using your simulator's
interface, then sends GDB the result. It is really like a stub, but
can do more thing because it is part of your simulator.

For more you can refer to Skyeye project, an open source simulator. I
can not remember the file name. But you can search "*gdb*" in the
source files. It is easy to find.

Wenbo

new simulator as a new gdb target

[s88]

Hi all:

       I have made a new ARM v5T's simulator. I wanna binding this
simulator with gdb and insight. So, the first step is to make my
simulator work with gdb...
I found in that $insight_home/src/sim/arm/wrapper.c play a role to
communicate the simulator and gdb withoud TCP. It looks simple. Is it
possible that I write a wrapper for my simulator?
But I still have no idea that how to binding those things (especially
for the gdb and my simulator).

Any suggestion is welcome!!

Thanx!

Dave.
