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,

the only way I know to unprotect the whole memory is clear the flags "TP", "BP2", "BP1", "BP0" into the status register and I do that as soon the program starts: are there others way to unprotect the whole memory space?

BTW: I've already tested your last suggestion and, unfortunately, both "sector" and "bulk" operations fails,

Thanks again, Regards

Maurizio
