Hi, I'm using CyclonIII with standard AS configuration scheme with EPCS64.My project includes writing/reading parameters to/from EPCS Flash memory by NIOS. How can I protect Configuration Image on EPCS Flash from accidental overwriting? Thanks.
EPCS flash devices have a block protection feature which helps to prevent unintentional data overwriting. You can select the protected blocks through a 3-bit configuration in status register.Refer to the EPCS datasheet, page 16 and following.
Thank you for your response.Yes, I know about this register but I don't realy want to alter EPCS Controller design in order to access this register. Is there another way to config this reg?
