Can anyone explain how to enable the ADC Clock Source on an STM32H753ZI using STM32 Cube?

I have been fighting against the same problem for the last few weeks. At one point in time, the ADC clock was miraculously turned on in CubeMX. Instead of fighting another battle against CubeIDE/CubeMX installation, I saved the working version of the stm32h7xx_hal_msp.c and reused it over the new one created by CubeMX.

Attached are the diff screenshot and function code.

void HAL_ADC_MspInit(ADC_HandleTypeDef* hadc)
{
 GPIO_InitTypeDef GPIO_InitStruct = {0};
 RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0};
 if(hadc->Instance==ADC3)
 {
 /* USER CODE BEGIN ADC3_MspInit 0 */
 
 /* USER CODE END ADC3_MspInit 0 */
 
 /** Initializes the peripherals clock
 */
 PeriphClkInitStruct.PeriphClockSelection = RCC_PERIPHCLK_ADC;
 PeriphClkInitStruct.PLL2.PLL2M = 4;
 PeriphClkInitStruct.PLL2.PLL2N = 9;
 PeriphClkInitStruct.PLL2.PLL2P = 4;
 PeriphClkInitStruct.PLL2.PLL2Q = 2;
 PeriphClkInitStruct.PLL2.PLL2R = 2;
 PeriphClkInitStruct.PLL2.PLL2RGE = RCC_PLL2VCIRANGE_3;
 PeriphClkInitStruct.PLL2.PLL2VCOSEL = RCC_PLL2VCOMEDIUM;
 PeriphClkInitStruct.PLL2.PLL2FRACN = 3072;
 PeriphClkInitStruct.AdcClockSelection = RCC_ADCCLKSOURCE_PLL2;
 if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInitStruct) != HAL_OK)
 {
 Error_Handler();
 }
 
 /* Peripheral clock enable */
 __HAL_RCC_ADC3_CLK_ENABLE();
 
 __HAL_RCC_GPIOF_CLK_ENABLE();
 /**ADC3 GPIO Configuration
 PF10 ------> ADC3_INP6
 */
 GPIO_InitStruct.Pin = GPIO_PIN_10;
 GPIO_InitStruct.Mode = GPIO_MODE_ANALOG;
 GPIO_InitStruct.Pull = GPIO_NOPULL;
 HAL_GPIO_Init(GPIOF, &GPIO_InitStruct);
 
 /* ADC3 interrupt Init */
 HAL_NVIC_SetPriority(ADC3_IRQn, 5, 0);
 HAL_NVIC_EnableIRQ(ADC3_IRQn);
 /* USER CODE BEGIN ADC3_MspInit 1 */
 
 /* USER CODE END ADC3_MspInit 1 */
 }
 
}

Thanks for the information. I downloaded the earlier version of CubeIDE and CubeMX but they don't allow me to open the files created by a new version. I have too much invested in the current project so I guess I am stuck with my method until the newer version fixes the problem.

I wish there were errata sheets of the software tools (maybe there are I didn't know) so I wouldn't spend so much time fighting the tools.

It's been two months and a new version of cubeMX still hasn't been pushed. When is this expected to be fixed and made available to the community?

Thanks for this post! After several hours of analyzing got enough for a decent Google search and presto, this thread! Kind of OK if every once in a while the problem isn't my coding! Alas too late to revert to an older CubeMX, so will go work on other parts of the project until the fix comes out. Hopefully soon though, it has been a while.

Just updated STM32CubeMX from Version 6.5.0 to 6.6.1.

After migrating the project to the newer version, I agreed to run the automatic clock issues solver and the ADC clock is properly configured now.
