By default the nios FLASH programmer doesn't recognise all serial FLASH parts.

You need to create a "nios2-flash-override.txt" file in your ../nios2eds/bin installation directory. By identifying the size and number of sectors a device has this file tells the programmer how to handle serial FLASH parts whose device ID it doesn't recognise.

In your new "nios2-flash-override.txt" file paste the following: 


sector_size = 65536
sector_count = 8

The FLASH programmer will now know how to handle your Spansion part.
