After this I can not type anything like stats in COM port window it is stop no update from Serial port I am edit program is like this...

1) In -qs_iot.c file

uint32_t g_ui32SW1Presses = 0;
uint32_t g_ui32SW2Presses = 0;
uint32_t g_ui32InternalTempF = 0;
uint32_t g_ui32InternalTempC = 0;
uint32_t g_ui32TimerIntCount = 0;
uint32_t g_ui32SecondsOnTime = 0;
uint32_t g_ui32LEDD1 = 0;
uint32_t g_ui32LEDD2 = 0;
uint32_t g_ui32LEDD3 = 0;
uint32_t g_ui32LEDD4 = 0;
uint32_t g_ui32LEDD5 = 0;
char g_pcLocation[50] = "";
char g_pcContactEmail[100] = "";
char g_pcAlert[140] = "";

tStat *g_psDeviceStatistics[NUM_STATS]=
{
    &g_sSW1Presses,
    &g_sSW2Presses,
    &g_sInternalTempF,
    &g_sInternalTempC,
    &g_sSecondsOnTime,
    &g_sLEDD1,
    &g_sLEDD2,
    &g_sLEDD3,
    &g_sLEDD4,
    &g_sLEDD5,

    &g_sLocation,
    &g_sBoardState,
    &g_sContactEmail,
    &g_sAlert,
    NULL
};

void
UpdateLEDs(void)
{
    //
    // If either LED's global flag is set, turn that LED on. Otherwise, turn
    // them off.
    //
    if(g_ui32LEDD1)
    {
        ROM_GPIOPinWrite(GPIO_PORTN_BASE, GPIO_PIN_1, GPIO_PIN_1);
    }
    else
    {
        ROM_GPIOPinWrite(GPIO_PORTN_BASE, GPIO_PIN_1, 0);
    }

    if(g_ui32LEDD2)
    {
        ROM_GPIOPinWrite(GPIO_PORTN_BASE, GPIO_PIN_0, GPIO_PIN_0);
    }
    else
    {
        ROM_GPIOPinWrite(GPIO_PORTN_BASE, GPIO_PIN_0, 0);
    }

    if(g_ui32LEDD3)
            {
                ROM_GPIOPinWrite(GPIO_PORTK_BASE, GPIO_PIN_0, GPIO_PIN_0);
            }
            else
            {
                ROM_GPIOPinWrite(GPIO_PORTK_BASE, GPIO_PIN_0, 0);
            }
    if(g_ui32LEDD4)
        {
            ROM_GPIOPinWrite(GPIO_PORTK_BASE, GPIO_PIN_1, GPIO_PIN_1);
        }
        else
        {
            ROM_GPIOPinWrite(GPIO_PORTK_BASE, GPIO_PIN_1, 0);
        }
            if(g_ui32LEDD5)
        {
            ROM_GPIOPinWrite(GPIO_PORTK_BASE, GPIO_PIN_2, GPIO_PIN_2);
        }
        else
        {
            ROM_GPIOPinWrite(GPIO_PORTK_BASE, GPIO_PIN_2, 0);
        }

}

2) In qs_iot.h

#define NUM_STATS                           16

3)In Pinout.c

ROM_GPIOPinTypeGPIOOutput(GPIO_PORTN_BASE, GPIO_PIN_0 | GPIO_PIN_1);
    MAP_GPIOPadConfigSet(GPIO_PORTN_BASE, GPIO_PIN_0 | GPIO_PIN_1,
                             GPIO_STRENGTH_12MA, GPIO_PIN_TYPE_STD);
    ROM_GPIOPinTypeGPIOOutput(GPIO_PORTK_BASE, GPIO_PIN_0 | GPIO_PIN_1 | GPIO_PIN_2);
       MAP_GPIOPadConfigSet(GPIO_PORTK_BASE, GPIO_PIN_0 | GPIO_PIN_1 | GPIO_PIN_2,
                                GPIO_STRENGTH_12MA, GPIO_PIN_TYPE_STD);

    //
    // Default the LEDs to OFF.
    //
    ROM_GPIOPinWrite(GPIO_PORTN_BASE, GPIO_PIN_0 | GPIO_PIN_1, 0);
    ROM_GPIOPinWrite(GPIO_PORTK_BASE, GPIO_PIN_0 | GPIO_PIN_1 | GPIO_PIN_2, 0);

Please help me in this and what is the problem in this.......
