STM32 cube mx generated code issue

Sup, engineers. 

I found some interesting issue in code, generated with STM32 cube MX. If I choose HSE as source for my PLL, it gives me following line of code in the RCC initialization function:

RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI|RCC_OSCILLATORTYPE_HSE;

That causes MCU stuck during RCC initialization. Replacing it with following line helps me to boot properly:

RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE;

Can anyone tell me, is that cube issue, or I am missing something.

When I set HSI48 Cube generates

RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI|RCC_OSCILLATORTYPE_HSI48;

but

RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI48;

only works for me.

Hi,

This issue is resolved with the new patch of STM32CubeMx v4.20.1

As you are using an old .ioc project, you should first EDIT the .ioc file and REMOVE the RCC.OscillatorType that you don't need, then re-generate the project.
