Problem
Is it possible to in-system programmability (ISP) update or program a MAX® II device design in the Configuration Flash Memory (CFM) without overwriting the contents of the User Flash Memory (UFM)?
Solution
Yes, it is possible to ISP program the MAX II device design in the CFM without overwriting the content of the UFM. The opposite is also true
- you can ISP program the UFM contents without overwriting the MAX II device design in the CFM. The Quartus
II Programmer provides the option to individually program :
- The MAX II device design
stored in the CFM block
- The entire user flash
memory (UFM) block
- Or the entire MAX II
device (CFM and UFM content)
