You still haven't told us anything about this thing that you're trying to program, nor what you're using to do the programming - so it's impossible to say what settings might be needed!
Again, remember that we know nothing about you or your equipment or anything other than what you provide in your posts.
A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
I am using STM32F030C6T6. I have a working circuit board. I am trying to connect to it to put a new program in it. The code was protected, I tried to remove the protection. Now when I try to program, I get different warnings. I don't know exactly what information you want from me.
