Re: Using GDB with M32R MSA2000 Board

["Noah Aklilu" <naklilu at ualberta dot ca>]

It still comes out with the same error (minus the backtrace)
about the bad value returned.  Unfortunately the mon2000
is a remote target, so there is really no way I can think
of logging that.  Is there a way to starting backend
logging with gdb?  

Well here is the result when I execute the gdb command:

m32r-elf-gdb -nw hello.exe

Mon2000>.
(gdb) quit
The program is running.  Exit anyway? (y or n) 

--end 

Now I am wondering if I have a different version of the
mon2000 monitor from what cygnus used to develop the
code for the toolset.  But when I read throught the
libgloss code, it says msa2000 in the comments. Hmmm.

Below is the output with the version of the monitor and
system captured from the terminal emulator.
