    Uart at 4Mbps.

      Hi,

         

      Right now, I am using fx3 uart at baud rate of 115200 for file transfer. I want to use uart at much higher baud rate 4Mbps. I change the baud uart config as given below(also changed buad rate on imx Uart to 4Mbps). But i am not able to get desired result, almost half of data packet lost.

         

      uartConfig.baudRate = CY_U3P_UART_BAUDRATE_4M;

         

      uartConfig.stopBit = CY_U3P_UART_ONE_STOP_BIT;

         

      uartConfig.parity = CY_U3P_UART_NO_PARITY;

         

      uartConfig.txEnable = CyTrue;

         

      uartConfig.rxEnable = CyFalse;

         

      uartConfig.flowCtrl = CyFalse;

         

      uartConfig.isDma = CyFalse;

         

      I even try at lower baud rate , it is working at 230400. But at baud rate higher than 230400 it is not working. Do i need to make other changes in uart configuration apart from baud rate to achieve desired rate.

         

      Please help me in this regard.
