Reading/Writing EPCS (MT25QU01G) with IP

Hi, Thank you for taking time to read this question. I am using a C10GX FPGA with a MT25QU01G serial flash memory. The overall goal is to be able to update the flash using the 'ASMI' IP. I beli...

    Sounds good, thank you for answering my questions.

    For future readers using cyclone 10GX with MICON MT25QU01G:

    1) You can reliably use "ASMII Parallel Intel FPGA IP" for single read writes (and use a slow, less than 20 Mhz clock).

    2) Use the "Generic Serial Flash Interface IP" if you would like to use a faster clock OR perform page writes.

    3) Ensure that bytes being written from the hexout data to the micron/epcs be byte reversed. Use https://en.wikipedia.org/wiki/Intel_HEX#Record_types for how to understand the record types.

    Best Regards.

Hi,


Yes, you can follow the clock limit set by the flash. Should not be any issue if it is set within the limit.


Regards,
