PFL and nios II control flash

[Altera_Forum]

hi, I am going to use PFL and AP configuration scheme in my Cyclone III with an external parallel Flash. In this Cyclone III, there is a Nios II processor, and I am going to put the Nios II imaging in the same Flash. Is that possible?

yes, you can boot a Nios from CFI flash

Is the answer still yes if the Cyclone III is a Stratix IV and you are using FPP instead of AP?
