If you are using a recent quartos, try using the newer boot code that converts avalon reads directly into epcq accesses.

You then point the nios reset vector directly at the flash address (which takes up 32MB of address space foe an EPCQ256).

Note that I've not used that logic, we load the nios over pcie.
