The NIOS II doesn't reply.

Hello,

Two things come to mind at the moment regardinging your problem.

1) Debug Core: Make sure that you have added a debug core to your processor in SOPC Builder. This is done through the Nios II editor (double-click on the cpu in the table). If you don&#39;t have a debug core for the processor, then you&#39;re out of luck. I can&#39;t remember if the Nios II IDE will tell you this, however. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif

2) Open Core Plus: If you are using an unlicense (evaluation) version of the Nios II core, make sure that you leave the open-core dilalog box running in Quartus. This message box will appear after you download the compiled SOF file to your board if it contains a Nios II processor. Don&#39;t click "cancel" on this message box if you intend to debug your system!!

Hope one of these solutions helps. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/biggrin.gif

hello,

everytime i want to connect to my nios ii via the byteblaster cable (at my lpt port) the following messages appears in the nios ii ide

using cable "byteblasterii [lpt1]", device 1, instance 0x00

pausing target processor: not responding.

resetting and trying again: failed

leaving target processor paused

the fpga is successfully programm with the nios ii design and the fpga works fine, if i program it with some "by-hand-made" designs.

what do i do wrong? the design in the sopc builder contains just the cpu a onchip memory and the jtag uart; nothing more, and i can&#39;t persuade it to work. :-(

can someone help me?

thanks.
