7 years agoYou need to add (or modify if already there) a "nios2-flash-override.txt" file to your Quartus installation. This tells the nios programmer some basic facts about the FLASH device (ID C84013) that it doesn't know about.
Refer to the following post:

Towards the bottom there is a file you can download. It tells you where to put it. You will need to add an entry for your particular device: EPCS-C84013 with sector count and sector size information - you'll get that from the datasheet for the 'EPCS' (equivalent) part you're using.
Cheers,
