Adc初始化后用HAL_ADCEx_Calibration_Start函数进行校准，一直返回失败，为什么？

使用的板子为NUCLEO-U575ZI-Q。
下面是初始化的代，请各位大佬解惑，困惑很久。

ADC_HandleTypeDef hadc1;

void HAL_ADC_MspInit(ADC_HandleTypeDef *hadc)
{
GPIO_InitTypeDef GPIO_InitStruct = {0};
RCC_PeriphCLKInitTypeDef PeriphClkInit = {0};
if (hadc->Instance == ADC1)
{
      PeriphClkInit.PeriphClockSelection = RCC_PERIPHCLK_ADCDAC;
      PeriphClkInit.AdcDacClockSelection = RCC_ADCDACCLKSOURCE_HSI;
      if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInit) != HAL_OK)
      {
         // Error_Handler();
      }

      /* Peripheral clock enable */
      __HAL_RCC_ADC12_CLK_ENABLE();

      __HAL_RCC_GPIOA_CLK_ENABLE();
      /**ADC1 GPIO Configuration
      PA4    ------> ADC1_IN9
      */
      GPIO_InitStruct.Pin = GPIO_PIN_4;
      GPIO_InitStruct.Mode = GPIO_MODE_ANALOG;
      GPIO_InitStruct.Pull = GPIO_NOPULL;
      HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

}
