Downloading ELF process failed. Connected system ID is also not found.

Question

Hello,

I'm using Altera 15.1.0.185 Lite Edition software to do a simple project using MAX10 FPGA, which consists of NIOS II Processor, on chip memory and Jtag UART in Qsys. Compilation is successful and the project is also built in Eclipse. While running project to the target device in eclipse, i'm getting an error "DOWNLOADING ELF PROCESS FAILED".

with reference to the previous discussions, i added system id peripheral in qsys to check whether the expected system ID is connected. While running the project through NIOS II Hardware, the error is " Connected system ID has not found on target at expected base address". By ignoring Mismatch system ID and System timestamp and clicking on 'SYSTEM ID PROPERTIES' in Target configuration tab, what i'm getting is

'connected system id : not found'

'connected system timestamp : not found'

tried to access through nios ii command shell, The response which i got from commands 1.)nios2-download -g <file_name.elf> && nios2-terminal 2.)jtagconfig -n are attached as images. Please check all the images.

If anyone knows to solve this, please help me asap.

Maybe the processor is in reset, because of some mistakes in the reset-chain of your qsys-project, please doublecheck also correct clocks.

Just to check, but are you sure that your Nios2 system is really being instantiated on the top-level module of the design ?  This could explain the inexistence of any ID loaded at the physical target.

You are getting a file not found error for your elf file.  Check that the file is there. If it isn't, look at the error messages you get when building. Check that full file permissions to write to the directory where your project is.

While building project, there is no error. elf file is generated whenever the project is built. Only thing is "DOWNLOADING ELF PROCESS FAILED" :(

But the same project is running in others system without any error and the output exists in NIOS II console also..
