How to remove write protection of STM32 chip?
Removing write protection on an STM32 microcontroller is necessary when the Flash memory or option bytes are locked, preventing you from programming or erasing the chip. This can happen due to incorrect configuration, security settings, or accidental locking. Below are the steps to remove write protection from an STM32 chip: 1. Identify the Cause of Write Protection Write protection on STM32 chips can be caused by: Option Bytes Configuration : The Read-Out Protection (ROP) or Write Protection (WRP) settings in the option bytes may be enabled. Hardware Write Protection : Some STM32 chips have a hardware write protection pin (e.g., nWRP ). Software Lock : The Flash memory may be locked by software (e.g., using the FLASH_CR register). 2. Tools Required ST-Link Debugger/Programmer : To connect to the STM32 chip. STM32CubeProgrammer : Software to configure and program the STM32. IDE (Optional) : STM32CubeIDE or Keil MDK for debugging and programming. 3...
