schmuel,

It looks like you're using a lead-free device. The flash programmer doesn't....yet, support these devices.

You need to save the following text to <nios2_install>/bin/nios2-flash-override.txt: 

 #  EPCS1N (lead-free)
sector_size = 32768
sector_count = 4
 #  EPCS4N (lead-free)
sector_size = 65536
sector_count = 8

Please report back with any further issues that you have.

Cheers,

[UPDATED]: Though I&#39;m not sure, you may have to modify the HAL flash abstraction commands....if you have a need to access the flash from your software.
