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
what do you mean with AP ?
I have googled and found some technical datasheets and developer documentation about the marvell pxa27 under this link/webpage http://www.marvell.com/application-processors/pxa-family/
I also asked lenovo about datasheets (not the short brief productsheet) to get facts about it. But again, I do not think that lenovo will ever support me in this case. if I got some datasheets and if its not against laws etc I will report it here.
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
That would be nice, hope they got some glues.
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.
Ok no major hints from them, they do have a 10 inch version of the same tablet lying around though so I will get them to post that up and have a look see if I can figure anything out.
If you had anywhere I can pull in what you have done already that would be handy.
Thanks, Charles
