When I start STM32G031J6(SO8N) PWM, the code jumps to label "Reset_Handler".

I generate the STM32 Project and define each PIN.

PIN1:GPIO_Output

PIN4:TIM2_CH1

PIN7:SYS_SWDIO

PIN8:SYS_SWCLK

And I let a code below run but it do not reach "while".

​

/* Initialize all configured peripherals */

 MX_GPIO_Init();

 MX_TIM2_Init();

 /* USER CODE BEGIN 2 */

 HAL_TIM_PWM_Start(&htim2, TIM_CHANNEL_1);

​

 /* USER CODE END 2 */

​

 /* Infinite loop */

 /* USER CODE BEGIN WHILE */

 while (1)

 {

  HAL_GPIO_WritePin(GPIOC, GPIO_PIN_14, GPIO_PIN_SET);

  HAL_Delay(10);

   HAL_GPIO_WritePin(GPIOC, GPIO_PIN_14, GPIO_PIN_RESET);

   HAL_Delay(10);

  /* USER CODE END WHILE */

​

   /* USER CODE BEGIN 3 */

 }

 /* USER CODE END 3 */

​

I run and investigate the code in step, and the code jumps to "Reset_Handler:" at the line "__HAL_TIM_ENABLE(htim);" in the API "HAL_TIM_PWM_Start".

The code repeats execution and reset. The GPIO pin is as above.

​

If I comment out "HAL_TIM_PWM_Start(&htim2, TIM_CHANNEL_1);" in the above code, it reach "while" successfully. The GPIO pin is as follows.

I set my project as default except for each PIN and TIM2. I set TIM2 Channel1 to "PWM Generation CH1".

Do I miss any necessary setting?
