STM32 Readout Protection (RDP)

All STM32 MCUs feature something known as Read Out Protection. It is probably a feature of the ARM Cortex core, since ST also provide something known as Proprietary Read Out Protection which is only available on certain STM32 models. In this document we will take a brief look at the basic Read Out Protection.

Test Example

Using the STM32CubeProgrammer we can read out the code (flash) of a STM32 MCU (in this case a Black Pill board).
