Flash Programmer, EPCS Reserved Fields are non-zero

Greetings - 

 

While trying to program a Spansion S25FL032P Flash device on my EP4CE10E22 Cyclone-IV board with the Nios II Flash Programmer, I get the following error messages: 

 

"Looking for EPCS registers at address 0x00011100 

Initial values: 9300023................. 

Not here: reserved fields are non-zero 

No EPCS registers found: tried looking at addresses .............. 

Error Code: 8" 

 

Do I need an override file and what should go in it? Any help would be greatly appreciated. 

 

Thank you very much,

I was able to solve this problem myself. The Flash Programmer tool seems a bit finicky in that I needed to load my target image into the FPGA using the Quartus-II Programmer tool, within the Flash Programmer tool, immediately before clicking the Start button in the Flash Programmer tool window.

And btw, I also needed the override file copied to the \bin directory. I added the entry:  

[EPCS-010215]# EPCS32N(lead-free) 

sector_size = 65536 

sector_count = 64
