Yes, I'm not too familiar with the nios boot loader, but the "Reset" vector will make a difference.

I would check the CPU settings and make sure the reset vector is looking at the CFI. If so I'm stuck, I would try to build in a signal tap and track where the CPU was fetching the first few instructions.

I've only dealt with a system that had EPCS memory for booting.
