STM32F103RET7 Conditions that prevent entry after setting RDP Level 2 or debugging.

[mckim0306]

Hello, I am using your STM32F103RET7 series.
We need the functionality of RDP Level 2.
Once you write, you have to implement something that can't enter and erase.
Is that function possible on this chip?
First of all, we are also reviewing STM32F205RGT7 chips.
Since the development has been completed with STM32F103RET7, it is best that this function can be implemented.

STM32F103 does not have a feature like RDP level 2. You can implement read protection, but the chip can always be erased. See the flash programming manual for details.

STM32F205RGT7 does have RDP level 2. You'll have to switch families if that's a requirement.
