The SH2's BSC can do eight bit memory no problem.  So yes, I'd
double-check that your bus speed and wait states are right.

Make sure you have the latest sh2 stub.  Seems like I recall a minor
glitch in the code that realigns memory accesses, where a particular
combination of access requests could cause it to do the wrong thing.

Finally, keep in mind that the standard sh2 stub doesn't do anything
with peripheral configuration.  To make things portable, I leave that
to a .gdbinit file.  It could simply be that you haven't turned
external memory on...
