Hello ZZYZX,

Please launch the PDF file atached as it will detail

the "Connecting Spansion SPI Serial Flash to Configure

Altera FPGAs" application note.

This application note supports the Altera EP3C55 FPGA and

Spansion SPI (S25FL064K as a minimum) for Cyclone III.

help progaming spansion mem chip I am trying to use quartus to program a Spansion chip (s25fl064k0smfi011) That is used with Cyclone 3 (EP3C55). Using the Progammer from Quartus 2, I use the Active Serial Programming Mode for the EPCS16 Device. When I select the Erase, it says "Programmer Operation Successful". When I Program/Configure the chip, it says "Programmer Operation Successful". But when I select Program/Configure and Verify, it fails on the verify operation. I then test out the FPGA and it does not work. Now here is the issue. When I first flash it is successful. Flashing the same thing also is successful. If I change the .pof, erase, then Program, it fails. I then try to erase and program the original .pof, it fails. Can anyone help?
