[En-Nut-Discussion] protecting memory from NutOS

[Hugo Simon]

Hi,

I built a memory mapped device which occupies the addresses from 0xb000 to
0xffff. So it lay "behind" the external memory of the Nut (AVR version).
This ist no problem because it's a write-only display memory of an LED
display.

How can I protect that memory from being used by NutOS and how can I define
an array that lies at that address range or maybe a pointer pointing to it?

Thank you
bye
