    SPI_SCK has a clock before configuring FPGA

      Hi all,

       

      I connected FX3 to an FPGA trying to configure FPGA using SPI.

       

      BASED on cypress document showed below, clock should start when I start configuring the FPGA but it is always there, from the time I turn on the board. when I run configuration another clock will be added on top of the other clock and ofcourse FPGA fails!

       

      what is going on?
