Does Generic QUAD SPI controller II support EPCQ-A devices

We use a EPCQ64A to configure a Cyclone V device. Now we plan to program it in field by an external processor. We managed to use Intel FPGA Generic QUAD SPI Controller II Core to erase and read EPCQ6...

Hi WGao1,

Generic QUAD SPI Controller II does not support EPCQ-A device.

For EPCQ-A device, we recommend to use Serial Flash Controller II Intel FPGA IP.

For write operation, make sure you set Write Enable Operation first. Then, Disable all Sector Protect. Then, perform Write operation.

Refer to my write operation below (I'm using Cyclone 10 LP, EPCQ64 device & Serial Flash Controller II Intel FPGA IP).

Thanks.

    Hi WolfGang, The Serial Flash Controller II Intel FPGA IP is not listed in the IP Catalog. Where can I download it? We have managed to program some data into the memory with Generic QUAD SPI Controller II by choosing STANDARD I/O mode. Is it equivalent to Serial Flash Controller II Intel FPGA IP? Many thanks Wei

      Hi WGao1,

      The Serial Flash Controller II Intel FPGA IP is not listed in the IP Catalog. Where can I download it?

      Go to Tools -->Platform Designer. The IP should show in IP catalog in Platform Designer.

      Yes, if you not using QUAD mode, you can use Generic QUAD SPI Controller II with EPCQ-A device.

      Thanks
