STM32CubeMX Clock Configuration not generating any code for LSCO Source Mux

[PCast.2]

Hi,

When selecting LSI as output for LSCO pin, and generating code with integrated STM32CubeMX, no output is seen on LSCO pin.

I have to manually add a call to this to see LSI on LSCO pin.

HAL_RCCEx_EnableLSCO(RCC_LSCOSOURCE_LSI);

When using MCO pin instead of LSCO pin, the code for source clock selection is generated correctly.

I'm using STM32CubeIDE v1.7.0. and STM32L432KCU MCU.

Thanks and kind regards,

Pedro.

Hi @PCast.2​ ,

Thanks for your feedback,

You are right, It seems that the STM32CubeMX does not generate the code to enable LSCO output, for now you have to add HAL_RCCEx_EnableLSCO(RCC_LSCOSOURCE_LSI); manually.

Your request have been reported internally, I'll keep you posted with the updates.

Sara.
