The desired location for FLASH memory will be at 0x0400_0000. This

That's OK. It will simply limit your SDRAM size to 64M.

And my cause other problems as well. Don't do it. Map flash at a

address.

Just to be explicit: you _must_ map your flash _well_above_

0xC000_0000

(the start of the linux kernel area) if you want to run linux.

I didn't know that about Linux... but who says I'm going to run Linux? (OK, I am, just kidding.)

Since _you_ control BR0 (don't listen to them hardware engineers), you can put it anywhere you want. 0xFF00_0000 is a good spot.

0xFFF0_0000

is not as good of a spot because it limits you to 16MB of flash.

Think

big. ;-)

0xFF00_0000 makes sense to me, and works fine. It fits in with what I've seen in other implementations. As I stated previously, 0x0400_0000 was a purely historical number. I'll take the recommendations of those who have been there before... thanks.
