First, which controller are you using? the legacy EPCS controller, or the new Altera Serial Flash controller?

For the legacy one, you should set NIOS II reset vector to EPCS controller, with 0x0 offset. For the new one, you should point NIOS II reset vector to EPCS, with reset vector offset value, which should not be 0x0. You need to consider the .sof size.

So the JIC file will be like this (just an example)

harware.sof 0x00000000 to 0x00fffffe

software.hex 0x00ffffff to 0x02776760
