You've made me curious enough - so, I've ordered some parts. I have a suitable Cyclone IV platform on which to try it. I shall report back here on Monday.

However, on paper I'm expecting it to work. The S25FL164K supports all the commands the EPCS does and is the successor to the S25FL064K - which happens to be used on the DE0-Nano development board. You can program that via .jic, specifying it as an 'EPCS64', without any problems.

As for the greyed out 'disable EPCS ID check' - I'm still on Q13.1 which gives me control of that radio button.

Cheers,

Alex
