Hello, 

I'm facing the same problem.  

With the bare on-chip memory my project works fine. After adding SDRAM controler with PLL (descriped there (ftp://ftp.altera.com/up/pub/computer_organization/de2-70/tutorials/tut_de2-70_sdram_vhdl.pdf)) i get error message during downloading .elf file. 

 

Any suggestions what should i do?

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"?

In the license set up I can see all the mega core functions as well. That means it picks my license correctly. And .sof file is also correct. Following is my full error message. 

"Launching 'new configuration has encountered a problem. Downloading ELF Process failed.'" 

 

Thanks Daixiwen.

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.

There is no error there, Eclipse isn't even trying to upload the software. That's very strange. Are you sure it isn't saying something else after that?

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

HOLLY MOLLY. This was the ONLY advice that worked! 

I was almost losing my head but as AR that I am, finally I crossed paths with this. 

It just worked!

I received same massage,“Launching New Configuration has encountered a problem”, "Downloading ELF Process failed" and I solved by check Pin Assignment . In Qsys SDRAM name SDRAM but pin name is DE1 is DRAM. I changed and OK. I hope it help you.

I solved it by checking all the connections in Qsys but was a bit disappointed because of the random errors keep popping up randomly and disappearing after restarting the IDE.

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

Did your design meet timing? Are you using SDRAM?

Hi 

My design does not contain SDRAM. Its a simple design. Now I have changed the quartus ii version to 10.0. Design is done in SOPC. Still no success.I have attached here. 

 

Thanks

Can you attached your Qsys design and Quartus project? I can't really see from your thumbnails (blurry)

Hi 

I have attached the a zip file here. File size becomes too large so I could not zipped all file. But you will find all necessary files here. I have tried here with quartus 13.1 version. All version must not create problem and I have tried several times and found most of the time its the matter of On_chip_memory2 although the connection seems working. Looking forward to hearing from you soon. I would be really happy to know where I am mistaking. 

 

Thanks
