Programming Altera CycloneV Active Serial x4 - Spansion FL256SAIF00 Problem

Hi, 

I'm trying to interface a Spansion FL256SAIF00 to a CycloneV FPGA using active serial x4 mode has anyone had success using a Spansion QSPI device for programming an Altera FPGA? 

A Micron 25Q256 works fine. I've tried disabled the device ID check in convert programming files but no luck so far. 

Any help is greatly appreciated.

I am having similar problems with S25FL256SAGNFI001 and Cyclone V. 

Can't get even 1x configuration to work.

So I sent spansion a question about this and here is their response: 

 

4-Byte addressing support is required to configure FPGAs from 256Mb or higher density SPI Flash. 

Altera requires specific operations to enter (4BYTEADDREN – B7 Command) and exit (4BYTEADDREX – E9 Command) 4-Byte addressing mode. 

Our S25FL256S does not support “B7” and “E9” commands, thus CANNOT be used to configure Altera FPGAs in Active Serial configuration mode. Hope it helps.
