STM32G0B0 - Timer with Interrupt issue

[SMari.1]

Code is very simple, not so many configs.

Issue arises when I call HAL_TIM_Base_Start_IT(&htim3):

/* Enable the TIM Update interrupt */

 __HAL_TIM_ENABLE_IT(htim, TIM_IT_UPDATE);

and code broke with no error on the Call Stack.

I tried the same code on NUCLEO-G071RB and it works as expected.

Here below the code..

int main(void)

{

 HAL_Init();

SystemClock_Config();

HAL_TIM_Base_Start_IT(&htim3);

while (1)

 {

}

}

void SystemClock_Config(void)

 RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};

 */

 HAL_PWREx_ControlVoltageScaling(PWR_REGULATOR_VOLTAGE_SCALE1);

 /** Initializes the RCC Oscillators according to the specified parameters

 * in the RCC_OscInitTypeDef structure.

 */

 RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI;

 RCC_OscInitStruct.HSIState = RCC_HSI_ON;

 {

  Error_Handler();

 }
