WebThis function sets up the RX ring buffer to a specific UART handle. When the RX ring buffer is used, data received is stored into the ring buffer even when the user doesn't call the UART_TransferReceiveNonBlocking() API. If there is already data received in the ring buffer, the user can get the received data from the ring buffer directly. Note WebFIFO overrun event is usually reported by kernel by printing this message on console: [ 483.380456] imx-uart 21f0000.serial: Rx FIFO overrun When dynamic processor's voltage/frequency scaling is enabled, Linux kernel performs a lot of transactions between different OPPs.
