Dear GDB gurus,
I'm new to this list, and I'd appreciate your expertise.
I'm developing a gdb-stub for a Hitachi platform. I'm done with the hardware
part, but my stub and the gdb have problem understanding each other.
I compile my test program and fire up the gdb...
(gdb) set remotedebug 1
(gdb) load
...

I would appreciate any light that you can shine on this. Do I need to patch
GDB? Do I need to process binary downloading (I don't do it now)? Add extra
cases to my command switch?
Thanks a lot!
Regards -- Alexei
