hi guy, I'm having a problem with my stm32l412kb when I'm trying to work with portC. I've looked at the schematic and I saw some switch. does someone here know how to control the switch?

What is this, https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-mpu-eval-tools/stm32-mcu-mpu-eval-tools/stm32-nucleo-boards/nucleo-l412kb.html ?

You may need to remove also the code which enables the LSE (i.e. click in CubeMX to disable LSE), as it overrides any GPIO settings for those two pins.
