I have the Cyclone II DSP Development Kit (2C35 device) but cannot get my "hello world" program to run. I always get the following message. Using cable "USB-Blaster [USB-0]", device 1, instance 0x00 Pausing target processor: not responding. Resetting and trying again: FAILED Leaving target processor paused I have carefully followed the steps outlined in the Nios II Development Kit Getting Started User Guide and everything works as expected, right up to the part that says "Click Run..." on page 1-14. I&#39;ve seen other postings with similar problems but I haven&#39;t seen resolution. If I&#39;ve missed something, please point me to the answers, posts, documentation, whatever. Is this a known problem? Is it possible that my "Nios II Device Drivers" project in the IDE is bad, causing this problem, because of earlier mistakes on my part? How can I recreate "Nios II Device Drivers"? Looking for any suggestions or ideas.

Make sure that all unassigned pins in the FPGA are in tri-state mode. If not (this is Quartus default unless you changed it), the board resets immediately after configuration and the processor vanishes. Avishay

Thanks, Avishay, for the suggestion. I checked the unassigned pins and they are already set to tri-state input, so I looked for other possible problems. I noticed something else that is probably causing my problem - now I need help to resolve it. In SOPC builder, I&#39;m using the standard reference design but I have an error and a warning at the bottom message window of the GUI. The error says "One or more components could not be located (ddr_sdram_component). Check search path under file->sopc builder setup... menu." I tried adding some directories like it said, but that doesn&#39;t seem to help. Next to the ddr_sdram component in the active components window, it says "(NOT INSTALLED)". Do I need to reinstall Quartus? How can I install just the missing component? (Where do I find it?) The warning says "nios development board, cyclone ii edition: SSRAM data byte-lanes are swapped. Refer to the Nios Development Board, Cyclone II Edition Reference Manual." Is this normal for this board? Do I need to correct this? Dave

Run your programm in simulator, is it work? Make sure that you have USB-Blaster [USB-0] only in jtagserver! It help me in solving the same problem=) Good luck!

So, please try this solution: 1. Install ddr Core 3.4.0 (If tou don&#39;t have, you can download the free evaluation on altera.com). 2. Open project menu, select Add/Remove Files in Project ... And in tab File, remove all the old version of ddr Core ( .vhd file ) then add the new version of ddr Core. And replace the path in user libraries ... 3. Open SOPC Builder. In Board Settings tab, there will be warning for unassigned pin of ddr, set them to assgined in quartus ii project. 4. Regenerate the system. 5. Re-compile in Quartus II. Thanks.

Hi all,

i also have this often re-occuring problem, could you please help me? Thank you in advance.

I have followed the example you may find in tt_nios2_hardware_tutorial.pdf (altera website.)
Everything goes fine to the point where I need to upload the program...
Then I get the error which I have mentioned above.
what could have gone wrong?

I use nios II IDE 7.0 and quartus II 7.0 for the DE2 (EP35) education board. (with one usb cable)
* I only use the free license.
> Could this be causing the problem?
* In the tutorial I have read the following:
"You must have an Altera USB-Blaster download cable, revision B or higher."
> How can I check if this is the problem?

I also have following questions:
- is there anybody who has succesfully completed the example?
(on the DE2/EP35 education board, with free license)

- are there other causes for my problem?

once again thank you in advance.

Some additional info:
I can create a simple NIOS II core in hardware on which I can upload a simple program with the "Altera Debug Client". For more complex programs I however would like to use the NIOS II IDE
