download software to de2 board

Every time, i try to download the "hello world" - example from the NIOSII IDE, i get the following error message.

*****************************************************************

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 have no idea, whats going wrong, because i can succesful configure my hardware/board with the "standard.sof" file under the examples folder of NIOSII IDE. After i doing that, i start the NIOS IDE, build a new project, based on the "hello world" example and compiled the source code, with no errors.

If the USB-Blaster [JTAG] want to download the software, the cpu doesn,t response.

In this forum, many other users have the same problem, but i have not fount a detail solution.

Is there a bug in the pin assignments of the example file?

Please help me. It frustrates me.

    After i designed my hardware with the SOPC Builder, i get the pins named "n_reset" and "clk". I mapped "clk" to the PIN_N2 location, but what is the setting for the n_reset-signal??? (DE2 Board with a Cyclone II EP2C35F672C6N)

    Which standard.sof file are you referring to? I'm not aware of any DE2-based "standard.sof" files. You need to use designs that are actually created (ftp://ftp.altera.com/up/pub/de2/de2_system_v1.5.zip) for the DE2 board. Any other designs will likely fail....in unpredictable (and perhaps) board damaging ways :-)

    ..\altera\kits\nios2_60\examples\vhdl\niosII_cycloneII_2c35\standard.sof

    This is the system, which i have use and it comes with the nios II ide installing.

    Next i have try to build my own hardware design:

    - niosII/e core

    - jtag_uart

    - onchip_memory (32kB) for software download

    But with the same result! --> CPU doesn´t response

    After i setting up my hardware in the sopc builder, i get a n_reset signal. Which pin / location have i to set for it?

    Right. My point exactly! That design will only function on the Altera Nios II Cyclone II Dev. Boards....not the DE2 board. Use one of the designs from the link I provided in my previous post as a starting point for whatever you&#39;re trying to do. At the very least, these designs should have the correct pinout.
