Processor not responding

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.

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'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'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?

Hello.

Maybe you need to install the Megacore IP library CD.

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!

Hi Dave,

Perhaps I used to have the same problem and someone in this forum helped me. 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.

Hello,

I was trying to run the board diag project on the standard for DE2 board and getting the similar problem. I didn&#39;t recompile the standard project but used the .sof file for programmer only and I think that should be ok (I don&#39;t need to recompile unless I want to add more hardware with the SOPC Builder right?). So I don&#39;t think error in compilation would result in this problem of processor not responding.

I tried several ways to overcome this but still didn&#39;t work. Any help would be very appreciated http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif

Thanks.

Hi,

I have just the same problem and I don&#39;t use any standard hardware. So you can calm down, and focus on other topics as just on the SD-RAM thing on your board. It must be a problem with the IDE.

If I find the problem, I&#39;ll post soon.

Good luck, I hope someone will find the solution and will post it.

Bye

I&#39;ve been having this same problem too. I get the error message:

Using cable "ByteBlasterMV [LPT1]", device 1, instance 0x01

Pausing target processor: not responding.

Resetting and trying again: FAILED

Leaving target processor paused

I can program my .sof to the board no problem, I can compile my C application too, but when i go to run the C code on the processor I get that error message. I can&#39;t even use the flash programmmer to program the flash memory either, I get an error along the same lines as the one above.

If anybody has any ideas i&#39;d greatly appreciate them.

The top two bytes of the SSRAM data are reversed on the NIOS II development boards Cyclone II edition. This is just a warning SOPC builder seems to take this into account.

I established a basic NiosII system in SOPC Builder,just like this:Cpu-NIosII/s,Jtag Uart&#65292;on chip memory-16K,led_pio-8 outputs.

I run the hello_led poject on my SOPC board-ep2c20,

after download my hardware system to the board and complie my software in NIOS IDE ,I run the project,but it couldn`t success.

The error informations are:

Using cable "Nios II Evaluation Board [USB-0]", device 1, instance 0x00

Pausing target processor: not responding.

Resetting and trying again: FAILED

Leaving target processor paused

I have cheched my Pins assignment , it was all right.

Please ,Please tell me how to solve?
