TMS320F28035: I2C Can't write more than 4 bytes of data

Hello c200 experts.

I am trying to send more than 4 bytes data via i2c but noting happens.

void I2CMaster_Transmit(Uint8 I2CSlave_Address, Uint16 I2CMaster_ByteCountTx, unsigned char *I2CMaster_TxArray, Uint16 I2CMaster_ByteCountRx, unsigned char *I2CMaster_RxArray)
{
    I2caRegs.I2CSAR = I2CSlave_Address;
    /***************Write******************/
    if(I2CMaster_ByteCountTx != 0)
    {
        I2C_s.I2CMaster_TransmitField = I2CMaster_TxArray;

        I2caRegs.I2CCNT = I2CMaster_ByteCountTx;

        while(I2CMaster_ByteCountTx > 0)    //check that there are still bytes to send
        {
            I2caRegs.I2CDXR = *I2C_s.I2CMaster_TransmitField;
            I2C_s.I2CMaster_TransmitField++;
            I2CMaster_ByteCountTx--;
        }

        I2caRegs.I2CMDR.all = 0x2E20;   // Set up the control register:
                                        // bit 14 FREE = 1
                                        // bit 13 STT = 1  (Start condition)

                                        // bit 11 STP = 1  (Stop condition after
                                        //                transfer of bytes.)
                                        // bit 10 MST = 1  Master
                                        // bit  9 TRX = 1  Transmit

                                        // bit  5 IRS = 1 to Reset I2C bus.

        StartCpuTimer0();               // Start the timer
        I2CMaster_Wait();               // Wait for I2C bus to clear
        StopCpuTimer0();                //No timeout, so stop the timer
        ReloadCpuTimer0();              //Reload the period value (35 ms timeout)
    }
    /****************Read*******************/
    if(I2CMaster_ByteCountRx != 0)
    {
        I2C_s.I2CMaster_ReceiveField = I2CMaster_RxArray;

        I2caRegs.I2CCNT = I2CMaster_ByteCountRx;
        I2caRegs.I2CMDR.all = 0x2C20;           // Send "repeated" Start with Read (TRX off)
                                                // and Stop.

        StartCpuTimer0();                       // Start the timer

        I2CMaster_Wait();                       // Wait for I2C bus to clear
    }
}

This is my write and read function. any help?

Also my master sides init function

void I2CMaster_Init(Uint8 I2CMaster_MasterAddress, Uint16 I2CMaster_Prescale)
{
    Uint16 i;

    I2C_s.TransmitBufferFirstIndex = I2C_s.I2CMaster_TransmitField;
    I2C_s.I2CMaster_ReceiveField = I2C_s.Master_ReceiveBuffer;

    for(i = 0; i<21; i++)
    {
        I2C_s.Master_ReceiveBuffer[i] = 0;
        I2C_s.Master_TransmitBuffer[i] = 0;
    }
    //Setup I2C interrupts and Cpu Timer 0 interrupt
    EALLOW; // This is needed to write to EALLOW protected registers
    PieVectTable.I2CINT1A = &i2c_master_int1a_isr;
    PieVectTable.TINT0 = &cpu_timer0_isr;
    EDIS;   // This is needed to disable write to EALLOW protected registers
    // Enable I2C interrupt 1 in the PIE: Group 8 interrupt 1
    PieCtrlRegs.PIEIER8.bit.INTx1 = 1;
    // Enable TINT0 in the PIE: Group 1 interrupt 7
    PieCtrlRegs.PIEIER1.bit.INTx7 = 1;
    // Enable CPU INT8 which is connected to PIE group 8
    IER |= M_INT8;
    // Enable CPU int1 which is connected to CPU-Timer 0
    IER |= M_INT1;

    InitI2CGpio();
    InitCpuTimers();

    ConfigCpuTimer(&CpuTimer0, 60, 35000);          //CPU Timer 0 interrupt after 35 ms (at 60MHz CPU freq.)

    // Initialize I2C
//    I2caRegs.I2CSAR = I2CMaster_SlaveAddress;       // Slave Address.
    I2caRegs.I2COAR = I2CMaster_MasterAddress;      // address as Master.
    I2caRegs.I2CPSC.all = I2CMaster_Prescale;       // Prescaler - need 7-12 Mhz on module clk
    I2caRegs.I2CCLKL = 10;                          // NOTE: must be non zero
    I2caRegs.I2CCLKH = 5;                           // NOTE: must be non zero
    I2caRegs.I2CIER.all = 0x3C;                     // Enable interrupts

    I2caRegs.I2CMDR.bit.IRS = 1;                    // Take I2C out of reset
                                                    // Stop I2C when suspended

    I2caRegs.I2CFFTX.all = 0x6000;                  // Enable FIFO mode and TXFIFO



    return;
}

My slave device is also a c2000 board.
