I am I am using DE2 and Quartus 8.0 web editionI started with the tutorial (Introduction to the Altera SOPC Builder Using Verilog Design) generated the processor, and compiled my code without a problem. Starting the programmer, I get "you are trying to use one or more time-limited megafunctions that supports the opencore plus feature that will not work after the hardware evaluation time expires. Refer to the evaluation window for evaluation time details" I press O.K. Then when I download the file lights_time_limited.sof I get a window "opencore plus status" saying "click cancel to stop using opencoreplus Ip Time remaining unlimited." clicking cancel (the only choice) In the message window, I get configuration succeeded one device configured. successfully performed operation and ended programmer operation. Now I use the altera monitor program to compile and download the example, compilation is O.K. but downloading I get using Cable "USB-Blaster [USB-0]" device 1, instance 0x00 Resetting and pausing target processor: FAILED leaving target processor paused. I tried more than one board, reset is connected to KEY, clock is connected ... same results.
In the Quartus II Programmer, you have to leave the "OpenCore Plus" Window Open to use the Processor. Don't click cancel until you are done running your Nios II Software.- Blair
