The driver could not get your device to go into "identify" mode.
This can happen for many reasons:
* FLASH is write protected (the "write" signal is not allowed)
* You've configured the driver incorrectly. You say that you have
2x16 FLASH - what does that mean [to you]? Show us your
configuration lines from the driver include files.
Note: the iPAQ flash is 2 devices organized in parallel to form a
32 bit path. It might be a good place to look for assistance.
