Dear all,

I am using STM32F4 Discovery board and have some problems with using DMA on USART.
The cause may be the unwanted left behind data inside USART RDR.

Would you please kindly give me instruction how can I flush data out of RDR after finish receiving data?

I am writing my own HAL driver for USART.
