How do I use N25Q512 Quad-SPI Flash, instead of ECPQ512?

I have a board designed to boot the Cyclone V FPGA from AS Flash, using a N25Q512A13G1240E chip instead of Altera's EPCQ512. (NB: This is a product, not a dev-kit) However, in Quartus Prime, th...

I come back to this issue which can be interesting to me if I would like to replace and EPCQL by a SPI MICRON Flash.

If the "ASx4 mode" is not supported by the EPCQ512, have you tried the "ASx1 mode" configuration ?

If the PCB, hardware is designed to support the ASx4 it should work with the ASx1 configuration. In that case only one SPI Data line is used instead 4 and the configuraton time will be slower.
