Perhaps the board has LA[n:31] connected to the address bus
of the Flash rather than the correct LA[n:30] signals.

If so, its a hardware error, and there is not much you can
do. Even if the chip has a BYTE# pin you can change modes
with, a 16-bit Flash usually has a DQ15/A-1 pin that LA[31]
would then connect to.

Just a thought ...

Cheers,
Dave
