There is another thing to do to enable the hole
64k address range in NutOS, other than modify
NUTRAMEND in nutinit.c to 0xFFFE? It seems
to not work here, on a mega128 + 128k SRAM,
memory tests with regular 32k version go well
both for below and under 32k limit. No ethernet
other devices hooked on memory bus.
Thanks,
