I am currently using:
Quartus II 7.1 full version with full license. Open Core plus. and I am using Altera's Stratix II GX PCI-E dev board to dev nios2 system. my NIOS 2 system is not functioning. It only includes nios2, JTAG UART, PIO, onchip ram and PLL to slow down the clock. I used the hellow pio example in the nios IDE. not working. hellow world small example, not working. when I check run the hellow world application in Hardware, I got the following error from the IDE console: Using cable "USB-Blaster [USB-0]", device 2, instance 0x00 Pausing target processor: not responding. Resetting and trying again: FAILED Leaving target processor paused do you have this problem you are using this board for nios 2 development? The PLL output works. I attached my customer LED IP to the system that only get the clk and I can see blinking. I also simulated the entire system in ModelSIM and it works since the hello world is printed to the JTAG console and I can see the waveform from the ModelSIM. my PIO LED is working. I have no idea how to fix this problem. Thank you.Link Copied

Hi ezhongsjm,
There is a new support solution posted on Altera's web site that documents these errors. It links to a related solution that lists patches to fix a problem with the OpenCore Plus circuitry in version 7.1 and 7.1 SP1. http://www.altera.com/support/kdb/solutions/rd07272007_849.html (http://www.altera.com/support/kdb/solutions/rd07272007_849.html)
