Have you downloaded the updated H8/300H that I checked in a few days
ago? If not then do so. Also you need to fetch the toolchain patches
from here:

http://www.ecoscentric.com/devzone/h8300.shtml

And rebuild the toolchain.


Finally, you can only run executables built for the h8300h_sim or h8s_sim
targets on the simulator. Executables built for a specific board will
not work.

[ECOS] How to use the simulator?

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

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