factory image write-protect

Hi all, 

 

My project includes remote programming for the fpga+nios updates and flash device we use is EPCS128.  

My question is how should I implement write-protect for the flash to protect factory image from unintended writing.  

Usually, the factory image is stored from address x"0" in the flash and I checked the EPCS128 datasheet and found out their sector protect bits only cover the higher address sectors. 

 

I guess what i want to do is quite common so i wonder how usually people do to get it? 

 

Thanks.
