Re: how to use spi interface with custom ip

How do you know when the flash has valid data?
Is the flash directly connected via SPI to this IP or via a master (in this case the flash is also a SPI slave)?
The custom IP with an SPI i/f can act as SPI slave device, but who is the SPI master?

You need to provide more details.

it is better to write SPI code yourself.
Your question is how to drive SPI flash?
you have to be more clear
