Firstly, is your usb blaster working? Can check if the jtag connection is working at the Quartus II Programmer.  

Secondly, have you successfully run full compilation in Quartus and downloaded the .sof file into your board?

Is your pins being assigned correctly especially you reset pin? The other thing you can check is the Nios II debug reset request. Is it connected to the jtag reset port?

Hello Bittersweet, 

 

I wrote a large post about pitfalls I fell into when trying to get Nios/e operational. 

You might want to look at "Read/Write data to SDRAM on DE0 nano using NIOS ii"

Which version of Quartus are you using? And can you provide me your design for me to take a look at it?
