[ECOS] How to use the simulator?

[caocangmou <caocangmou at sina dot com>]

I'm using hitachi 2168.I want to use gdb/simulator for debugging. My configuration is fairly simple,using infra ,ecos kernel , HAL h8/300h variant ,and my 2168 board platform .when I run gdb in cygwin,it performs as follow:  
$ h8300-elf-gdb hawk
GNU gdb 5.2.1

This GDB was configured as "--host=i686-pc-cygwin --target=h8300-elf"...
(gdb) target sim
Connected to the simulator.
(gdb) load

(gdb) disassemble __start

0x200a <__start+10>:    7a 00 00 00 20 22 mov.l #0x2022,er0
0x2010 <__start+16>:    79 09 00 08       mov.w #0x8,e1
End of assembler dump.
(gdb)

I do not know why should this happen.How to use the simulator?
Thanks in advance.
