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.
Might it be that the design connects the flash A(-1) not to A(0) of the CPU? Or might it be that the flash is actually connected 16-bit wide, but you programmed the bus interface to be 8-bit wide? Both variants would lead to such a doubled answer.
