Help needed about GDB remote debugging, FORCE boards, Zylog serial controllers

[julienb at hathor.cst.cnes.fr (Julien BEERNAERT)]

Hello there,

My goals are to get a GNAT/RTEMS cross development environment for Sparc
based FORCE CPU-2CE board on a Sun Solaris host.

I use a dummy BSP inspired from the ERC32 and Bare ones.
I'm working actually in getting a gdb remote interface monitor on the
FORCE target.
I found the sparc-stub in gdb distribution (rdbmon, remcom.c). I'm
searching for general or specific informations about :

- How to adapt this stub to build a loadable monitor from the openboot
monitor (by default on FORCE board) ?

- Must the application program be loaded using gdb through the debug
serial line or must we use the basic command of the openboot monitor to
load application before debugging ?

- Samples source code for driving AMD Z85C30 serial controller (in the
project of the sparc-stub modifications).

Thanks,
