New ContributorCycloneV (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 Katuhiko,
Do you mean you want Nios II processor application execute-in-place from EPCQ flash??
Please refer to the Configuration user guide for information.

Regular ContributorHi 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".

New ContributorThank 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?
