Not entirely unexpected I guess, but certainly my gut feel here
is that this is a problem with the chip selects. I guess really
trying to find any available documentation on the AP/SPI and
tearing apart the SPI driver are the next steps from here. But
afraid I don't really have any great ideas for diving much
deeper. I will try to chase the Windows guys here again and see
if I can gain any clues from them but I don't really know at what
level these things are abstracted in Windows and thus if they can
really help us much.
Thanks,
Charles
