Cyclone II Configuration Basics

I am designing with the EPC3C5F256C8N. I will initially configure with the EPCS4 and then,later, configure from a serial flash via a microcontroller. I have been digging through the Altera...

Hi,

the EPCS devices are compatible with all the FPGAs which support Active Serial configuration. In fact, EPCS are plain serial flash.

A common setup is to have AS+JTAG, without any pin headers in the AS signals, only for the JTAG signals.

This requires use of JTAG indirect programming to read/write the EPCS but it's more practical than having two sets of pin headers for the ByteBlaster.

The document you want is the Cyclone III handbook configuration section.

I don't think there's any documentation on designs which support more than one configuration scheme (other than JTAG) though.
