Problem erasing EPCQ flash memory on INTEL Cyclone evaluation board with Generic Serial Flash Interface Intel running on NIOS II

As mentioned above, I'm not able to erase Flash Memory (neither sectors, sub-sectors, or bulk) using the Generic Serial Flash Interface Intel running on NIOS II: only with "Quartus programmer" I can....

Hi,

For the FW i've got inspiration from the example provided by INTEL (https://fpgacloud.intel.com/devstore/platform/2179/) but I've modified the code to fit the EPCQ-A datasheet requirements and Operation Code.

Note that only "erase" command doesn't works, while Read and Write works well.

I really don't understand why and I hope you can help me

Thank you

Maurizio
