This is jpe1313,
What I was saying was that are any of your entries your generated *.dts file "unknown." Take a look. If they are "unknown" then it COULD be a problem. For my custom design my "timer" was undefined and I had to define it properly. As far as the SD card. To clarify, I am not using the SD card in my design. I have a daughter card that has a Compact Flash.
Let me know if you need more help - but check your DTS

I was not able to post without administrator's approval. So i sent my message here. I maybe wrote 5-6 times but it seems all admins are sleeping.
Anyway, i have no unknown parameters.

And i also made my friend compile my kernel and .sopc file and tried to new zImage but terminal gave me same output :/
root@F15:~# altera/12.1/nios2eds/bin/nios2-download -g /home/student/Downloads/zImage
Using cable "USB-Blaster [8-1]", device 1, instance 0x00
Pausing target processor: not responding.
Resetting and trying again: FAILED
Leaving target processor paused
I hope you can even help further.
