I'm facing an issue i cannot figure out. I'm currently working on a stm32l073 and using the following RTOS : RIOT-OS. When i wake up from stop mode, UART seems to be desynchronized because wrong characters are displayed.
I have noticed that when i'm decreasing system clock, AHB clock and ABP clock all is working fine. Am i doing something wrong or do i need to reconfigure clock in the interrupt that is waking up the CPU from stop mode (this a RTC interrupt) ?
If you have any ideas about this issue, feel free to share your thoughts
