Epcs16 configuration

[Altera_Forum]

Can i configure the serial configuration device (epcs16) without having the fpga in the circuit? If so how? I couldn't find any documentation on it

The EPCS devices are SPI Flash. The configuration handbook describes the serial protocol, as do the data sheets for the Spansion S25FL series devices

Dave, 

 Thanks for your reply. But I am still confused. When I try to flash the EPCS device, Quartus programmer shows an error saying the silicon ID can't be recognized. Can Quartus programmer actually load the .pof file into the epcs device?  Erick

Dave, 

 Is an Altera part.. I got it from Digikey PN# 544-2567-5-ND.    Thanks, Erick

Have you probed the board with an oscilloscope and checked the waveforms?  You can also talk to the flash directly, eg., create a Qsys system with a PIO component and connect the pins from the PIO to the flash.  I've used that method to test SPI and QSPI flash devices.  Cheers, Dave
