How to let STM32F303 to enter STOP mode and wake up by UART

[frank239955]

Dear

I try to porting the sample code (from STM32Cube_FW_F3_V1.11.0\Projects\STM32303E_EVAL\Examples\UART\UART_WakeUpFromStop) to my PCB board with STM32F303RC, but I can't wake up MCU from STOP by UART

Is there anyone know whether the example code is ok to run or not
