Hello,
According to the datasheet for the serial flash device, the data transfer should be compatible with either of the conditions CPOL = 0, CPHA = 0, or alternatively CPOL = 1, CPHA = 1. I assume that you are operating both devices from the same Vdd supply of 3 volts.
Perhaps you might post the SPI communications code you are using, and provide more detail on the nature of the problem you are experiencing.
Regards,
Mac
