Yes I have and we already know it doesn't work - and unfortunately we were
not contracted to do a port to that chip/board combination.

Probably the "only" thing that needs fixing is the DRAM/MMU setup, since
that's the only difference I could see (purely from the point of view of
the eCos HAL port) between the older EB7111 board and the EDB7111-2 board.
And even that may just be a case of setting it up to use the MMU setup that
is currently configured only to happen for the EP7211 port. But I'm not
sure :-), I've never had the time to find out.

Yes, the cl7111_gdb_module.bin file is for the "EB7111" board.
