I have a very strange issue with STM32F407ZG; sometimesthe RDP level 1 is automatically set and then using STLink Utilities I can goback to RDP level 0.
BUT, Now I get RDP level 1 SET and I can't go toRDP level 0 : Seems to be Irreversible (like RDP level2).
I can connect with STLink utilities, to read theoption bytes and I see RDP Level1 and I'm not able to modify it to go to RDPlevel 0.
Canany one help please ? it is urgent!
