Exploring why GSFI IP Core repeats sending command and address for each 4-byte data in Page Program

Hi Aik Eu,

Thank you for the reply!

According to the provided link, the GSFI IP Core doesn't support burst writing of 256-byte pages. It's important to note that the ASMI Parallel II Intel FPGA IP exclusively supports EPCQ, EPCQ-L, and EPCQ-A devices. In cases where third-party flash devices (like Micron Flash Memory) are employed, the recommended option is the Generic Serial Flash Interface Intel FPGA IP, as specified in the ASMI Parallel II Intel FPGA IP User Guide.

Furthermore, the ASMII Parallel II IP Core isn't available in Quartus Prime Pro Edition, as we are working with Agilex 7 FPGA.

For optimal performance in SPI mode, we can utilize the SPI 4-wire IP Core instead of the GSFI IP Core. However, how can we achieve the best performance when operating in quad mode?

Thanks.
