Re: Illegal address in DataPort

Well I see your point. But the expansion flash area on a Tini 390 module is
not needed by the OS, this is still in CE0* space though.

With reference to the memory map:
http://www.systronix.com/tinistik/memory_map.html

My guess is that CE0*, CE1* and CE2* are all protected, which would mean
from 0x600000 upwards is OK. Try reading there and see what happens.

Mark.
