Right, thats I made sure to say; Physical Memory Map.

For example, on the Artesyn manual on their PrPMC they give a
physical memory map, and in the Yosemite board, there is a
physical memory map. I know many of the memory areas can be
redefined in hardware to have a different memory location, but
its still a physical address.

Still not right. Even the physical memory is software settable. What
matters is what chip-select things are hooked up to, and=20

then map those

chip selects correctly (size, base address, access with and so on)

Hi Rune,

Thanks for responding.

Thats what I meant with 'redefined in hardware'. But yes, redefined
up to the limit of the wiring on the board of course (chip-selects
and bus widths). That's where having the board schematic is
invaluable.

Does that sound right?

Yes.
