Hi

,

Try to disable the

Systick interrupt

/* Enter Stop Mode */HAL_SuspendTick();HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI);HAL_ResumeTick();

Hi

ELMHIRI.Syrine

I am having a similar issue although I have been able to wake up from STOP mode. I have a device connected to an I2C and SPI port which work fine after this but I am losing a device connected to the UART port. Is there something special I have to do to before entering stop mode for UART ports?
