Ah. The trouble may be that there are two "claim" words. One is

Perhaps I mixed up those two.  But because the current code works for
me, that means claim does map the memory.

But does the current code work for you when you comment out the BAT initialization?

(I was just speculating about two similar but different claim commands before; I need to look into it more.)
