Intel: Can I use Nios® II and Intel Serial Flash Controller II to Sector Protect for EPCQ128 (not EPCQ128A)?

Nios II

Category: IP (Other)
Tools: Quartus® Prime
Device: EPCQ


The Intel Serial Flash Controller II (Altera Serial Flash Controller II up to 18.0) driver has a problem and needs to be fixed.
This problem has been confirmed up to Quartus® Prime Ver.18.1.

Specifically, since the Write Enable Command was not issued to the Flash before the Sector Protect took effect, it is necessary to add that process.
Please use the attached file after correction.
