CycloneV (5CEBA2F23C7) is used. I want to use a configuration pin as a user pin. Pin number is not displayed in Pin Planner. Even if defined in the qsf file, a fitting error occurs.

    Hi Kato,

    Those pins are not dual-purpose pin check pin connection guidelines. So we can't use it as user pins.

    However, we pin DATA[5:15] as user pin.

    Go to Quartus II Assignments menu -> Device -> Device and Pin Options -> Dual-Purpose Pins window, choose the value "Use as regular I/O".

    Regards

    Anand

      Thank you very much.

      I want to write an NIOS program to an empty area of the config ROM.

      Cyclone III (EP3C16F484C6N) could use the configuration pin

      (It was a dual-purpose pin)

      Can the CycloneV configuration ROM be used for NIOS?
