You shouldn't generate an .hex file from your application. This is only used when the CPU can directly access the program memory, so for example when using a parallel flash or an on-chip memory. When using the EPCS you need a "pre-digested" version of the .elf file, written on the EPCS just after the .sof image. The elf2flash commang line tool can convert a .elf to an .srec ready to be written to the EPCS using nios2-flash-programmer. IIRC the graphical version of the Nios II flash programmer can also do both steps directly from Eclipse.
