Trouble with C code - Setting up UART with e2studio - c

Question

I'm currently doing a project, using RL78G14 as microcontroller. The project involves making an IR remote and control panel. If been trying to write code to setup a UART. I get an few warning messages of passing an incompatible pointer type when passing TxBuf and RxBuf, and my UART doesn't seem to work. Can anyone help me with the code?
void main(void)
{
R_MAIN_UserInit();
uart1Status = R_UART1_Receive(&RxBuf[0],1); // Prime UART1 Rx
while (1U)
{
//Check if byte received on UART
if (RxFlag)
{
// clear rx flag
RxFlag = 0U;
//Echo back the received character
TxBuf[0] = RxBuf[0];
//Send TX buffer, and specify how many characters to write
uart1Status = R_UART1_Send(TxBuf,1);
// re-Prime UART Rx
uart1Status = R_UART1_Receive(RxBuf,1);
}
//If a character has been transmitted
if (TxFlag)
{
// End of UART2 transmit
TxFlag = 0U; // clear tx flag
}
}

If you are using development board, R11 Pin check. It is connected to CAN RXD chip TJA1050T, and hence not receiving any data. Cut R11 jumper and it will start working.
Did you Started UART1 ? need to start it in Initialization.
