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.
