I have a new problem about serial communication. When UART sends and receives data quickly, there will be FIFO error.

This is my code

Hi @昌�?� �?�​ ,

Could you please share more details on your board and the hardware setup, the MMDV version on which you are based on, and if you've made some modifications ?

How did you configured the UART (baudrate), and do you use HW flow ctrl (DSR/DTR, RTS/CTS) ?

Thanks,

BR,

Christophe
