STM32G431RB seems to crash when "HAL_TIM_Base_Start_IT" and "HAL_TIM_PWM_Start_IT" are called

[FBurk.1]

Hello everybody,

I bought a STM32G431RB Nucleo. I created code for it with the STM32 CubeMX and modiefied the code in the STM32 CubeIDE. I want to access "HAL_TIM_PeriodElapsedCallback" and "HAL_TIM_PWM_PulseFinishedCallback", I read that this is possible by calling "HAL_TIM_Base_Start_IT" for "HAL_TIM_PeriodElapsedCallback" and "HAL_TIM_PWM_Start_IT" for "HAL_TIM_PWM_PulseFinishedCallback". But when I do that, the STM32 seems to crash.

Am I doing something wrong, or is this simply not possible?

Thank you in advance!

int main(void)
{
  /* USER CODE BEGIN 1 */
 
  /* USER CODE END 1 */
 
  /* MCU Configuration--------------------------------------------------------*/
 
  /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
  HAL_Init();
 
  /* USER CODE BEGIN Init */
 
  /* USER CODE END Init */
 
  /* Configure the system clock */
  SystemClock_Config();
 
  /* USER CODE BEGIN SysInit */
 
  /* USER CODE END SysInit */
 
  /* Initialize all configured peripherals */
  MX_GPIO_Init();
  MX_LPUART1_UART_Init();
  MX_TIM4_Init();
  /* USER CODE BEGIN 2 */
 
  // For some reason I can't have both Base_Start_IT and PWM_Start_IT
  HAL_TIM_Base_Start_IT(&htim4); // Calls HAL_TIM_PeriodElapsedCallback
  HAL_TIM_PWM_Start_IT(&htim4, TIM_CHANNEL_1); // Calls HAL_TIM_PWM_PulseFinishedCallback
  HAL_GPIO_WritePin(GPIOA, GPIO_PIN_5, 1); // Never gets reached
 
  /* USER CODE END 2 */
 
  /* Infinite loop */
  /* USER CODE BEGIN WHILE */
  while (1)
  {
    /* USER CODE END WHILE */
 
    /* USER CODE BEGIN 3 */
  }
  /* USER CODE END 3 */
}

More than likely the interrupts are being called so frequently that your main loop cannot progress. You're calling multiple interrupts every 200 timer ticks. That's not a lot of time.

Slow the timer down by a couple of orders of magnitude and try again.

Hello TDK,

thanks a lot for your reply, it was correct!

I have similar problem with my code that used to work on 431KB nucleo board, but fails on my prototype with 431RB MCU. 

Debugger does not step over HAL_TIM_Base_Start_IT(&htim1);

static void MX_TIM1_Init(void)
{

  /* USER CODE BEGIN TIM1_Init 0 */

  /* USER CODE END TIM1_Init 0 */

  TIM_ClockConfigTypeDef sClockSourceConfig = {0};
  TIM_MasterConfigTypeDef sMasterConfig = {0};

  /* USER CODE BEGIN TIM1_Init 1 */

  /* USER CODE END TIM1_Init 1 */
  htim1.Instance = TIM1;
  htim1.Init.Prescaler = 128;
  htim1.Init.CounterMode = TIM_COUNTERMODE_UP;
  htim1.Init.Period = 100000;
  htim1.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1;
  htim1.Init.RepetitionCounter = 0;
  htim1.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_DISABLE;
  if (HAL_TIM_Base_Init(&htim1) != HAL_OK)
  {
    Error_Handler();
  }
  sClockSourceConfig.ClockSource = TIM_CLOCKSOURCE_INTERNAL;
  if (HAL_TIM_ConfigClockSource(&htim1, &sClockSourceConfig) != HAL_OK)
  {
    Error_Handler();
  }
  sMasterConfig.MasterOutputTrigger = TIM_TRGO_RESET;
  sMasterConfig.MasterOutputTrigger2 = TIM_TRGO2_RESET;
  sMasterConfig.MasterSlaveMode = TIM_MASTERSLAVEMODE_DISABLE;
  if (HAL_TIMEx_MasterConfigSynchronization(&htim1, &sMasterConfig) != HAL_OK)
  {
    Error_Handler();
  }
  /* USER CODE BEGIN TIM1_Init 2 */
  HAL_TIM_Base_Start_IT(&htim1);
  HAL_NVIC_EnableIRQ(TIM1_UP_TIM16_IRQn);
  /* USER CODE END TIM1_Init 2 */

}

If i step into the HAL_TIM_Base_Start_IT(&htim1); and step by step, it returns OK.

Any ideas what might be wrong? Tried using FW 1.5.1 , 1.5.2 , 1.4.0 , no difference.

I found this to solve my problem (boot_lock) , not sure what that option byte does or if i can program it via Stm32Cube IDE
