    I really hate the new Eclipse environment that Altera created, it hides the real error message from nios2-download. I think you can see it somewhere in the console but Eclipse hides it almost immediately after the fail. It is important to get to it to know if the problem is a system id check failure, if it is because the CPU isn't responding or a memory verification fail.

    Yeah. In new console there is no error message is showing. I copied the error when its running. Actually the real problem is my nios system target connections couldn't get the correct name of nios cpu and the jtag uart cable. Following is the error i see in nios console.

    Pausing target processor: OK

    Hi

    Im using NIOS II Embedded Design Suite 15.0.0.v.20150423-0554, eclipse kepler service release 2 build id:20140224-0627.

    i got this from the console

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

    Processor is already paused

    Initializing CPU cache (if present)

    Not quite sure why it fails can anybody please give an explaination (could it be related to write to onchip memory from vhdl code ?), my onchip memory is from 0x8000 to 0xFFFF

    Hi

    I am also facing the same problem. There is no error in program. I have tried with version - 10.1,11,12.0,12.1 and 13.1. I have also tried with the demo program and My_First_niosII program and followed the instruction. Lastly I have tried using NiosII command shell. Still no success. Its really disappointing. I have attached the screenshot of of output from NiosII command shell.

    Please somebody help us...

    Thanks

    Please exit Nios SBT, then delete .megadata folder in the same directory with your software and bsp projects. It works with me all the time.

    I'm using altera quartus ii 12.1 subscription edition and i'm having the same problem when running the nios ii programme. It compiles fine. I have added system id component and checked again. It didn't solve the problem. Then I removed .metadata folder and contents in the software folder and run the project again. It was not the solution for me. Later I reset the USB blaster path. However I still have this problem. It seems the problem is with Nios ii subscription license. I'm using floating license server in Quartus ii. I set the path of nios ii license in the same settings path separated by ; symbol. Is it the correct way to add the license to nios ii ip core (/s or /f)?

    Thanks in advance for any help you can do.

    You can check if Quartus picks your license correctly in the "License Setup...." window from the Tools menu.

    You can also check the name of the generated .sof file. If it is something like "yourproject.sof" then the license was picked and used correctly, but if it is something like "yourproject_time_limited.sof" then the license wasn't used and you need to be tethered with the USB blaster to use the Nios CPU core.

    Could you give the full error message you get, before "Downloading ELF Process failed"?
