MN10300 Architectural Simulator Setup

The MN10300 simulator is an architectural simulator for the Matsushita MN10300 that implements all features of the microprocessor necessary to run eCos. The current implementation provides accurate simulation of the instruction set, interrupt controller, timers, and serial I/O.

In this release, you can run the same eCos binaries in the simulator that can run on target hardware, if built for ROM start-up, with the exception of those that use the watchdog timer.

However, note that AM33 devices required to run eCos are not simulated; therefore you cannot run eCos binaries built for the AM33 under the simulator. For the AM33, the simulator is effectively an instruction-set only simulator.

To simplify connection to the simulator, you are advised to create a GDB macro by putting the following code in your personal GDB start-up file (gdb.ini on Windows and .gdbinit on UNIX).

define msim   
 target sim --board=stdeval1 --memory-region 0x34004000,0x8
  
 rbreak cyg_test_exit   
 rbreak cyg_assert_fail  
end

You can then connect to the simulator by invoking the command

msim

(gdb) msim

You can achieve the same effect by typing out the macro’s content on the command line if necessary.
