STM32H563 DAC1

[mccabehm]

I used CubeMX 6.12 to generate code and DAC output works as intended.

I cloned that project, migrated to CubeMX 6.13 and generated code. DAC output doesn't work. Migration to 6.13 also used FW H5 1.4 instead of 1.3.

Comparing stm32h5xx_hal_msp.c I see the 6.13 generated code lacks

RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0};
if(hdac->Instance==DAC1)
{
  /* USER CODE BEGIN DAC1_MspInit 0 */

  /* USER CODE END DAC1_MspInit 0 */

  /** Initializes the peripherals clock
  */
  PeriphClkInitStruct.PeriphClockSelection = RCC_PERIPHCLK_DAC;
  if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInitStruct) != HAL_OK)
  {
      Error_Handler();
  }
}

in HAL_DAC_MspInit(). When I add the above code to stm32h5xx_hal_msp.c in the migrated project, DAC output works as expected.

No significant differences between the IOC files.

Is there a problem with CubeMX 6.13?

Attaching STM32H563VIT6_2.ioc (original, CubeMX 6.12, DAC works) and NGC_HW_Verification_Clone.ioc (cloned, CubeMX 6.13, DAC doesn't work).

What its doing, if you select using FW H5 1.3 again ?

[mccabehm]

I do not know how to revert a project to an earlier CubeMX and FW version. Using STM32CubeIDE v1.17

[AScha.3]

go : menu -> help -> configuration tool -> manage embedded...

then:

select (green button) to delete...and select other version -> green = active is the most recent/newest.

So deselect 1.4  on H5.

btw

You see, i still use 1.11.2 H7 - why should i update, if everything i use is working fine ?

Just to find new errors...?

[mccabehm]

I had to update to get correct VREFBUF handling for H563.

Deselecting H5 1.4 won't affect existing project. From what I've seen, this is only used when a project is created. The only H5 1.4 options are Refresh and Remove...

[AScha.3]

So you need to use v 1.4 ? (as i understand it...)

>From what I've seen, this is only used when a project is created.

try: open Mx view, then generate code . -> compile and check it...
