Did you change reset vector in NIOS 2 CPU point to epcs flash.

In my project with DE2-115 board, I stored FPGA configuration in EPCS64, it has 8MB space and software in CFI_FLASH. In order to do that, I did these following steps:

+ CONFIG EPCS64 with .pof file (ACTIVE SERIAL PROGRAMMING mode instead of JTAG)

+ Make some changes with the SOPC builder: Your SOPC builder need to have CFI_FLASH or EPCS_CONTROLLER and change NIOS2 reset vector to EPCS or CFI flash

+ Regenerate BSP settings in ECLIPSE

+ USE NIOS2-flash programmer as user guide on altera wiki

good luck with that
