Here are some things to check:

1) Use the system ID peripheral and make sure the Nios II IDE checks it

2) Make sure you have the correct download cable selected

3) Make sure you have met timing in Quartus II

4) If you are using a Nios development board make sure unused I/O are set to tri-state (this is the usual setting for most boards but make sure you know what you are doing before making this setting change)

5) Make sure you have assigned your I/O to where you expect (if you let Quartus II auto assign I/O it will put the I/O wherever it makes sense in terms of timing)
