Downloading ELF Process failed!

I am running NiosII IDE on my windows 7 professional laptop. When I first create a sopc project and complie and download *.sof into target board, then I also create a demo NiosII project "Hello world!" and debug it normally. Howerver, after I close NiosII IDE and restart it, I cann't debug it anymore eventhrough I don't change anything in both Quartus and sopc. It gives me a prompt that "Lanching hello_test Nios II hardware configuration has encourntered a problem. Downloading ELF Process failed". No matter I restart my laptop or power off my target board, it doesn't work! If I rebuild a new same sopc project and rebuild a new same NiosII project, it can work.But there is the same problem if I close it and restart it again. Please help me!:confused::confused::confused:

    Hi,

    I'm also facing similar issue while running a simple hello world project through 'Nios II Hardware configuration'. Please see the attachment for details.

    Thank you

    Make sure that timing is closed on the JTAG interface. USB Blaster II cables run at 24MHz by default. This should be constrained in your Quartus project like this: 

    create_clock -name {altera_reserved_tck} -period 40 -waveform {0.000 20} { altera_reserved_tck }

    If you need to slow down the clock rate with a USB Blaster II cable, run this command in a Nios Command Shell or Windows Command Shell. 

    jtagconfig --setparam 1 JtagClock 6M

    Sounds like the problem I have every time I restart Quartus (which, as often as it crashes, is very often).

    Try your first download after restarting from "Run Configurations..." rather than directly running something from the launch history. Once it gets back in sync, then running from the launch history works until you restart Quartus.

    First off, I'd try getting the IDE/SBT for Eclipse out of the way.... From a "Nios II Command Shell" (or a properly configured shell on Linux) change directories to where your ELF file is stored and type the following command: 

    nios2-download -g <your ELF.elf> && nios2-terminal

    and report what you see back here. If this command doesn't appear to work, please also try typing: 

    jtagconfig -n

    and report the results here, as well.

    This will help to determine whether the issue you're seeing is GUI/Eclipse related, JTAG chain related, hardware/FPGA design related or...something else.

    Cheers,

    I finially fix it by updating NiosII 10.0 sp1 to 10.1. Downloading the program after "Run Configurations..." to check whether the mcu is in sync. Maybe Version 10.0 sp1 is a bug one.

    Try to remove the terminal before quiting NIOS2-IDE, click on the red button in the console to finish the connection before you quit NIOS-IDE.

    By the way, use the console. Nios-ide is too buggy
