boot multiprocessor from one EPCS device

Hey, everybody, I'm using a system with 2 Nios II and I'd like to put the whole system (including the software of the 2 Nios) in flash memory (EPCS). But I do not know how to put the 2 *.elf file ...

As I said before, don't make 2 elf files. Make one elf file only. In your code have something like: 

main() {
   if (value of sysid register == 1)  // Look up how to get this in the Nios documentation
      processor1_main()
   else
      processor2_main()
}
