FX3 application access to SPI flash on DVK board
I've been able to boot OK from SPI flash on the DVK board. I would now like to read / write memory on the flash part, but have been unable to do so.
One possible problem is the Chip Select Line - I stepped through all of the GPIO pins, toggline one at a time, watching on a scope, and none of them appear to be hooked to the SPI Chip Select. (I Did monitor Chip Select during an SPI download from the host, and it went low, during that process, so I believe that I am, at least, looking at the correct line)
