HI, firstly im new into subject of STM32MCUs. I made my own board based on STM32F2 MCU. I have configured 2 interrupts one based on TIM 11 and one on Button placed at pin 40 (PC9). It is simple code including blinking LED every one second and switching different LED state after pushing button. I will pass my NVIC configuration in screenshots. I discovered that pushing button executes EXTI9_5_IRQHandler() when button is pressed but does not call for HAL_GPIO_EXTI_IRQHandler() innside function mentioned above. I discovered it by placing funcion to toggle LED in EXTI9_5_IRQHandler(). Timer interrupt of courese does not work either. I have no idea what is wrong.
