      Hi,

         

      I am using S70FL01GS as a serial flash interface to nxp k64 series controller. I am not able to get the flash working.

         

      I configured spi in mode 0 and also tried with mode 1, but the flash ic does not respond after i send command 0x9f other commands also do not work.

         

      I can see the clock and sdo signal from the controller to the IC using oscilloscope, but no response on sdi line. I have made hold signal high, cs low and

         

      reset is permanently connected to the ground, cs1 is made high

         

      The flash ic does not respond in any situation. kindly help me out with a solution for this.

         

      reference designs, sample code will be appreciated.
