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 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.

The pin you want to use

1.AS_DATA0 / ASDO (AB4)

2.DCLK (V3)

3.AS_DATA1 (AB3)

4.nCSO (R4)

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".

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?
