May I know the quartus version and Development kit that you using?


You need to have an EPCS flash controller in your SOPC design. Then you need to set the reset vector of your NIOS to the EPCS flash.


In order to write your sof and elf to flash you have to use Nios Flash programmer or Nios flash programmer command line with the link attached here: https://www.intel.com/content/www/us/en/docs/programmable/683118/current/overview-of-the-flash-programmer.html


You may also refer to this link for additional information:https://www.intel.com/content/www/us/en/support/programmable/articles/000081656.html


Hope this could clarify your doubts.


Thank you.
