    SPI Port Usage - General or boot flash only?

    jeffuf16

      Hello,

       

      The Joule documentation indicates that there are 2 SPI interfaces offered, one with 2 chip selects and one with 3 chip selects.  I'd like to connect the SPI from the Joule to an FPGA on my custom expansion board as a general communication interface (Joule is master, FPGA is slave).  My concern is that I've heard the SPI busses on Intel devices want to be connected exclusively to SPI boot flash devices.

       

      So the question is, can the Joule SPI interfaces be used as general communication interfaces to devices other than boot flashes?

       

      Thanks,

      Jeff
