Thanks for the suggestions. I finally found it in the wee hours this morning, and it was operator error. The CY14 by default powers up in the write protect state and from the factory is erased to all zeros. So my writes and subsequent reads appeared to fail by the "fact" that I could never read what I wrote. Guess I need better reading glasses in my old age :-/ Anyway, I'm happily up and talking using the Freescale SPI driver and spidev. Thanks for the help and sorry for the noise on the list.
