Cube 4.20 bug - Clock initialization

I found a bug in the new Cube Version.

At line 1 internal oscillator is enabled although it is not used, in fact it is not actived:

RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI|RCC_OSCILLATORTYPE_HSE
|RCC_OSCILLATORTYPE_LSE;
RCC_OscInitStruct.HSEState = RCC_HSE_ON;
RCC_OscInitStruct.LSEState = RCC_LSE_ON;
RCC_OscInitStruct.PLL.PLLState = RCC_PLL_NONE;
if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
{
 Error_Handler();
}�?�?�?�?�?�?�?�?�?

This brings HAL_RCC_OscConfig() to fail (timeout).

Thanks and BR,

Andrea

Sorry for such inconvenience.

I confirm the bug. Replicated using STM32F4-discovery board. When configure HSE, this 'RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI|RCC_OSCILLATORTYPE_HSE;' bug will occure.

Seem to be several people with similar/familiar issues with current release of CubeMX across platforms.

Please do more regression testing before releasing broken code to the ecosystem, the Adobe/Microsoft model for releasing streams of differently broken, but never fully fixed code, is really NOT appropriate for embedded systems where installed lifespan may exceed 10 years.

Hello,

The RCC config issue is fixed in the new patch CubeMx v4.20.1

So, please download and update the new version to resolve this issue.

PS: if you are using an old .ioc project, you should first EDIT the .ioc file and REMOVE the RCC.OscillatorType that you don't need

E.g: remove this line

RCC.OscillatorTypeHSI=RCC_OSCILLATORTYPE_HSI

Then re-generate the project, this will resolve your problem.

Best Regards

Imen
