How do I create a EPCS serial flash controller using the "Generic Serial Flash Interface Intel FPGA IP" controller in a Max10 device. The EPCS serial flash controller is not supported in Max 10 device.

I would like to instantiate the equivalent of an EPCS serial flash controller, used by an old Cyclone I design, in a Max10 device. I have instantiated a "Generic Serial Flash Interface Intel FPGA IP"...

Hi JJens15,

First

Generic Serial Flash Interface IP is not support Active Serial (AS) configuration scheme for Max 10 device (configuration data),

Max 10 only supported for General purpose memory which are:

  • Read device ID
  • Enable sector protect
  • Perform sector erase
  • Read and write data from and to flash devices

Second

Generic Serial Flash Interface IP is not support EPCS device. The supported Intel flash devices for configuration memory are, EPCQ, EPCQ-A and EPCQ-L.

I hope this will help.

Thanks.😉

    I can use a different device with no problem, but that isn't really the question. There are devices with a single data IO pin available.

    The question is, why does the Generic Serial Flash Interface IP create a component with 4 output data pins? I only want one.

    Is the hardware somehow configured to for data IO on only one pin, even though 4 show up in the BSF?

    Is there a way to instantiate a serial flash controller with a single data IO pin?
