FPGA fallback (factory) image in EPCQ256 using local upgrade

Hi,

I boot my Cyclone V from a EPCQ256. I would like to have a fallback image as well as an application image on the EPCQ256. If I understand correctly I have to configure the EPCQ256 for 3-byte addressing, but Quartus configures it for 4-byte addressing.

Is there any guide for using a fallback image with EPCQ256?

Thanks in advance!

    Could someone please explain what this means:

    "A Programmer Object File for Local Update is a Programmer Object File that consists of a local update enabled Programmer Object File and additional local update enabled SRAM Object Files, and is used to program configuration devices in local update configuration mode. You create a local update enabled Programmer Object File by adding local update enabled SRAM Object Files to a Programmer Object File in the Convert Programming Files dialog box."

    source: http://quartushelp.altera.com/15.1/#reference/glossary/def_pof.htm

    How do I create a "local update enabled SRAM Object Files"?
