How to interface serial Flash (non Altera)?

Dear expert,

Does anyone know how to interface with non-Altera external SPI serial Flash (SST25VF016B)? In SOPC builder which interface should I choose? Default SPI or EPCS Serial Flash Controller?

Thanks,

Skw

    Dear jakobjones,

    Thank you for the answer.

    No, I don't have my board ready yet but I will try with EPCS core when it ready.

    Btw, do you know if it is possible to use more than one EPCS core in one NiosII processor?

    I am not specifically familiar with the SST25VF016. Examine the datasheet and compare it with the datasheet for Altera's EPCS devices:

    I'm going to assume that you can probably use the EPCS core. This provides you with a software driver for accessing the flash. If you use the SPI core, you are on your own for the software driver.

    Do you have a board already? If it were me, I'd drop in the EPCS controller and just try it.
