Using cable "USB-Blaster [USB-0]", device 1, insta

[Altera_Forum]

Hi, everyone, I met a strange problem. 

 After I compiled the project(standard project, I added usb host IP core and assign pins) in Quartus II 5.0 successfully, and download the .sof file into the Altera dev board, Stratix edition, when I want to run a simple project in NIOS II IDE 5.0 with a hello world template, then a problem occurs in IDE console. It does well in first time, but when I want to run it again, can not any more. Here is what happened in console.  >>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 search this problem in google and other search engines. FAE in altera had explained this problem before, with two possible reasons. One is accidental error between Nios II CPU and IDE software through USB-Blaster, and you could resolve this problem with downloading the sof file and run again. The other was making the tools consistency(Nios II IDE 6.0, Quartus II 6.0), rebuilding the system again.  I followed the instruction, but can not get the right result!  And some guys say it is related with clock and time sequence of sdram, but does not give the solutions.

I had the same problem... I had made mistakes in pin assignments and that was the error. make sure all pin assignments are correct

I have the same problem.  

I have an Altera DE1 Board. I downloaded more then one time the sof file and Nios and I got each time the same problem. I&#39;m using NIOS II with only onchip memory and JTAG communication. So I think this problem couldn&#39;t be caused by the SDRAM.  Ideas to solve the problem?

Thanks, guys!

Try isolating the cause first. Disable a few SOPC Builder components at a time and tie those output pins to something safe (high or low). If you still have problems keep reducing the system until you determine what the culprit is. If you get down to an onchip memory, jtag uart, Nios II and still can&#39;t download code then start checking Quartus settings. 

 Once you have solved the problem just add the components back in. By the way, the method I recommend people bring up a design is to start small then add to the design. That way you don&#39;t have to debug a complicated system that you end up having to tear apart to find issues.  99% of the time I see this issue caused by one of two things:  1) Incorrect pin assignments 2) Unused I/O not set to input tri-state (common mistake when using Nios dev boards)  Also I recommend searching for one of the strings for the error output like "Pausing target processor: not responding". You will find other posts on this topic as well.

I agree the floor.

Hello Everybody, 

 I've a serious problem, can anyone guide me plz it is really urgent, m a beginner with Nios II IDE , and i was trying to upload hello World program into the DE2 but i face all the same problem: when i click on Run As: 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 followed all the steps on the tutorials, but i could not troubleshoot the problem. I tried version 7 and version 9.1 on Windows 7 and windows XP, same thing I checked the pin assignment, there is no error, Can any one guide me plz,    thank you

Hi,

I understand that this thread is very old. don't know if anyone else is having this issue.

I had this issue while working with Cyclone 10 GX with Nios Processor. The issue was with the reset pin.

The reset pin I used was an Active Low pin where as the Reset IP core in the Platform designer was Active High by default. In this situation, either don't connect any pin to the Reset pin of Nios processor or change the Reset IP parameter setting as Active Low.

Hope it helps.
