Compiler/F28M36H53C2: F28M36H53C2: UART RX FIFO

Part Number: F28M36H53C2

Tool/software: TI C/C++ Compiler

Hello,

I'm facing a configuration issue with UART FIFO.

My UART is configured as fallow:

void BSL_UartInit()
{
	//Initialize the UART
	//Set the baud rate = 115200
	//Number of data bits = 8
	//Turn off parity
	//Number of stop bits = 1
	UARTConfigSetExpClk(UART0_BASE, SysCtlClockGet(SYSTEM_CLOCK_SPEED), 115200,
			(UART_CONFIG_WLEN_8 | UART_CONFIG_STOP_ONE | UART_CONFIG_PAR_NONE));
	//Enable trasmit and receive FIFO
	UARTFIFOEnable(UART0_BASE);
	//Registers of UART interrupt
	UARTIntRegister(UART0_BASE, UartIntHandler);
	//Enable UART interrupt
	UARTIntEnable(UART0_BASE, UART_INT_RX | /*UART_INT_RT |*/ UART_INT_BE);
	//Enable the UART
	UARTEnable(UART0_BASE);

	UartTxFSM.status = UART_TX_FSM_IDLE;
}

So I write the follow code to receive data from UART:

#define UART_RX_BUF_LENGTH (32)
#define UART_ADDRESS	(0x10)
#define END_BYTE 0x7E

struct {
	enum {
		UART_TX_FSM_IDLE,
		UART_TX_FSM_TX_BREAK,
		UART_TX_FSM_TX_DATA
	} status;
	unsigned char buf[UART_TX_FIFO_LENGTH];
	unsigned char address;
	//unsigned char len;
	unsigned int len;
} UartTxFSM;

struct {
	int idx;
	int timeout;
	int error;
	unsigned char buf[UART_RX_BUF_LENGTH];
	int len;
} UartRx;

void UartIntHandler(void)
{
	unsigned long status;
	char data;
	unsigned char ck = 0xff;
    
	//break received
	if(status & UART_INT_BE)
	{
		UARTIntClear(UART0_BASE, UART_INT_BE);
		data = UARTCharGetNonBlocking(UART0_BASE); //discard empty data
		UartRx.idx = 0;
		UartRx.timeout = 0;
		UartRx.error = 0;
	}

	//if(status & UART_INT_RT)
	//{
	//	UARTIntClear(UART0_BASE, UART_INT_RT);
	//	UartRxTimeout = 1;
	//}

	if(status & UART_INT_RX)
	{
		UARTIntClear(UART0_BASE, UART_INT_RX);
		data = UARTCharGetNonBlocking(UART0_BASE);
		if(UartRx.idx == UART_RX_BUF_LENGTH || data & 0x00000f00)
			UartRx.error = 1;
		else
		{
			UartRx.idx++;
			UartRx.buf[UartRx.idx] = data & 0x000000ff;
			ck += data;
		}
         }
}

At the end, the UartRx.buff contain only 0x7E value, that is the last value sent from the other device.

Am I missing something?
