How to code to implement WRP (write protection)?

[Shinya]

Hello, Is there any tip or reference code to implement WRP? I need to prevent changing original codes and adding any other codes from malicious third parties.

I use stm32f303k8 and CubeIDE.

I appreciate any help you can provide.

Hello @伸弥 北郷​ ,

You should be able to change the settings in STM32CubeProgrammer.

Please check RM0316, "4.3.2 Write protection" section for more details.

FAQ: What are option bytes in STM32 and how do I use them?
