Honored ContributorDownloading ELF file onto target NIOS processor Failed
Hello,
When I build and download my Hello World application using the 'Run Configurations' GUI menu in Eclipse, I get a 'verify failed' error. Anyone know what this indicates and how I can resolve this? Below is the error I get when I try to run my application. Thanks, Nishanth using cable “usb-blaster [usb-0]”, device 1, instance 0x00processor is already paused

Altera_ForumWhat is located at the failure address?

I am assuming the executable I just downloaded.

Let me rephrase that....which hardware component (memory, epcs, etc.) is located at the failing address:

Try to run it from an onchip memory, i presume you are running it from some external memory...
(if it works with onchip it is for sure a timing problem, take a look on how to configure the PLL degrees of an external mem) - Altera_Forum
It is running on external SDRAM. Thank you very much for the suggestion. I will try running it on on-chip ram and see if it makes a difference.

Hello there, I'm having the same problem here since I set my NIOS reset_vector to the external EPCS flash memory from the external SDRAM.
But, if I make a JIC with my Sof and Elf files and then burn the flash, it works fine. Otherwise (with the reset vector at SDRAM) the software would not boot. Make sure your reset_vector is at SDRAM so it will not load the software image at flash upon your just downloaded elf at sdram. - Altera_Forum
That did it. Thanks, wgutstein! and everyone else for the support.

BTW the correct way to do this is to set reset vector to a non-volatile memory, say ext_flast and the rest to sd_ram.
It should work in any case - whether you run from a flash or dowloading sof and run sw in the nios tools. - Altera_Forum
make sure you have download the programming file .sof or .pof in your FPGA

typical error, probably clock problem of a external memory
