Hi!
I try to realize a remote upgrade system for MAX10(10M08DCU324C8G). I use On-Chip Flash IP Core for access to internal flash memory.
Regretfully I could not get access to CFM0 because bit 9(CFM0 protection bit) of Status Register is set to 1.
I setup Access Mode as read and write in IP Parameter Editor but it did not help and bit 9 is still set.
May be some one know how to solve this problem?
Thanks.

Hi MKuli5,
You need to disable write protection CFM0 in order to get access.
For example:
Your CFM0 is use Sector ID 1 & Sector ID 2.
If you look at On-Chip IP Control Register, Bit Offset 23 & 24 is write protection for CFM0 (Sector ID 1 & Sector ID 2).
Thus, you need to set these bit offset to 0.
I hope this will help. Let me know if you need more understanding.
Thanks.😉
