ELF file fails to load

I just did a clean install of v.10 development tools for Quartus and NIOS on my Windows 7 32-bit machine. The tools are running in Admin mode and I am able to download the .SOF file to the board using the USB byteblaster.

In to run my source file, I have to select Ignore mismatched system ID and Ignore mismatched system timestamp.

A dialog box opens and says the Download Elf process failed.

The message that I get in the console is

Using cable "USB-Blaster [USB-0]", device 1, instance 0x00

Pausing target processor: not responding.

Resetting and trying again: FAILED

Leaving target processor paused

help is appreciated

    I've stated it before (on these forums) and now I'll state it again. This sort of issue is nearly always caused by some sort of hardware error... For instance, forgetting to connect a clock or connecting reset such that it's always enabled would cause this to happen.

    Cheers,

    I am using the 50 MHz clock and trying to run a simple processor interface which should load without a problem.

    The reset line is connected to SW9 and I keep it high to allow the processor to load just like I did in previous versions of the tool.

    For a sanity check, just to see if it was a Win7 problem, I downloaded and installed the V10 on XP.

    It gave me errors again on the Time Stamp and System ID but does think it is loading the ELF file. After toggling the SW9 it does fail to load as expected.

    However, the problem on the XP is the code doesn't do anything so I still think there is a problem.

    My suspicion is the JTAG interface to NIOS is flakey :cool: .
