Configuration Flash Memory For Cyclone IV E - Military Grade?

Hi JohnT,

Thanks for that.

So are the parts I chose compatible and I can do QSPI interface?:

Cyclone IV E &

MT25QL256ABA8E12-0AUT

Is Quad-SPI parallel and not serial?

What I've done for the last two projects is to use one 10-pin connector to program the flash as well as interface to the FPGA using the a module instantiated inside the FPGA for AS mode.

That way, I can program through the FPGA via AS mode.

Can you please point me in the right direction for documenation, and provide some information on how to connect up QSPI to the FPGA?

Also, how do I set things up in the FPGA HDL to utilize QSPI?

Please elaborate, so that I can gain a better understanding and move forward.

Thanks again for your help...
