Similar question to "I'm a STMCube Newbie. I'm under the impression when I set up the clocks in STM32CubeIDE, it should generate all the clock configurations. Right now I'm not getting the RCC_PeriphCLKInitTypeDef PeriphClkInit = {0}; Should it be there."

Does anyone have the same issue?

I also want the cubeMX to add "RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0};"automatically command in "void SystemClock_Config(void)" function, but it isn't.

I mean this is in msp file under peripheral init...

I'm sorry, but would you be able to provide more detailed information?

In src folder you have generated file stm...._hal_msp.c and in it

for example

void HAL_LTDC_MspInit(LTDC_HandleTypeDef* hltdc)
{
  RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0};
  if(hltdc->Instance==LTDC)
  {
  /* USER CODE BEGIN LTDC_MspInit 0 */
 
  /* USER CODE END LTDC_MspInit 0 */
  /** Initializes the peripherals clock
  */
    PeriphClkInitStruct.PeriphClockSelection = RCC_PERIPHCLK_LTDC;
    PeriphClkInitStruct.PLLSAI.PLLSAIN = 66;
    PeriphClkInitStruct.PLLSAI.PLLSAIR = 2;
    PeriphClkInitStruct.PLLSAIDivR = RCC_PLLSAIDIVR_2;
    if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInitStruct) != HAL_OK)
    {
      Error_Handler();
    }
 

simply use Search in your project ...
