RTOS/EVMK2H: I can't read a 0xff byte over the UART

Part Number: EVMK2H

Tool/software: TI-RTOS

My program is run on ARM cores and sending is ok over the UART(uart1).

But, I can't read a 0xff byte.

Other bytes (0x00 ~ 0xFE) is read.

I used blocking mode, callback mode and polling mode and all mode don't read a 0xff byte. 

PDK version is 4.0.9 .

My settings are as follows

    UART_Params_init(&uartParams1)
    uartParams1.dataLength = UART_LEN_8;
    uartParams1.stopBits = UART_STOP_ONE;
    uartParams1.parityType = UART_PAR_NONE;
    uartParams1.baudRate = 57600;
    uartParams1.writeDataMode = UART_DATA_BINARY;
    uartParams1.readDataMode = UART_DATA_BINARY;
    uartParams1.readEcho = UART_ECHO_OFF;
    uartParams1.readReturnMode = UART_RETURN_FULL;
    uartParams1.readMode = UART_MODE_CALLBACK;
    uartParams1.writeMode = UART_MODE_CALLBACK;
 

Thanks.
