Hmmm, maybe I must try changing that, then. That might be the answer to all the confusion.
Although it is definitely an 8MB flash, and I thought it was supposed to be at the end of memory?
Well, obviously, the address lines are connected up such that all accesses in that section wrap into the flash, whatever the offset is.
Unfortunately, but understandably, it makes no difference whatsoever to the behaviour of the flash chip. I can still put it into QRY mode, where I get the doubled QQRRYY response, but the flash is not detected any better than it was previously.
I suppose my next best option is to try to ask the Linux kernel folk if they have any ideas.
