I have written STM32F103RBT6 independent watchdog process, development environment the Keil uVision4 (MDK4.12) program, you will see: When the program is downloaded to the STM32 the LED0 (PA8) just bright one, and then would have been bright When this statement in the while loop: IWDG-> KR = 0xAAAA commented out, download the program again to STM32, will see LED0 stop flashing.
