Programming MX29GL512 over PFL - Programming MX29GL512 over PFL Hi. We have to program flash device attached to the MAX II. Previous version of board was assembled with Spansion S29GL512P. As replacement has been chosen Macronix MX29GL512. Unfortunately this model is not on the support-list (Quartus 18.1) and Programming ends with Error: 1) Will be this model supported in next version of Quartus? 2) Am I able to force different type of CFI device or define own type of flash? 3) Is possible to ignore ID checking?
