Hello together,
I'm working with an STM32F37 MCU and have somme issues with the USART1 Clock Mux.
I enabled the Receiver Timeout Interrupt to detect the end of a Modbus message. With the HSI clock the interrupt occurs as expected. If I switch to the PCLK2 no interrupt will be triggered whilst the rest of the MCU is working fine.
Please see the picture below to get a clue of my clock configuration.
Thank you in advance for your support.
Regards
Phil
