First of all. ¿do you add the system ID component in the SOPC Builder or Qsys Editor? When you add a nios processor you have to check the "cpu id" option.

Don't forget, in the nios eds ide, to regenerate the bsp for your system, and the try to download the elf file. ( Ignore the timestamp mismatch during communication ).
