AM1808 flashing "blink.c" in nand flash

sir,

I am using OMAP-L138 serial flash utility to burn my blinky code to nand flash. I used ubl_AM1808_NAND.out and Blink.out to create an AIS file "ubl_blink.bin". It gets written to nand flash successfully. Here is the command prompt output.

NOW,

when i switch off my board, change switch configuration to nand boot mode and then switch on the board, i get following text on tera term:

AM1808 initialization passed!008D37.

UBL Version: 1.65

after this nothing happens. Every time i press reset button with switch configuration in nand boot mode, i get the same message.

I am using OMAP-L138_FlashAndBootUtils_2_40. Below is my code for blinky. I am using ccsv5

#include<stdio.h>


#define SYS_BASE           0x01C14000
#define GPIO_BASE			0x01E26000
#define KICK0Ra             *(unsigned int*)(SYS_BASE + 0x038)
#define KICK1Ra             *(unsigned int*)(SYS_BASE + 0x03c)
#define PINMUX11a             *(unsigned int*)(SYS_BASE + 0x14c)
#define PINMUX12a             *(unsigned int*)(SYS_BASE + 0x150)
#define DIR45a             *(unsigned int*)(GPIO_BASE + 0x060)
#define OUT_DATA45a            *(unsigned int*)(GPIO_BASE + 0x064)
#define SET_DATA45a             *(unsigned int*)(GPIO_BASE + 0x068)
#define CLR_DATA45a             *(unsigned int*)(GPIO_BASE + 0x06C)

void DEVICE_kickUnlock();
void UARTConsolePuts(unsigned char *str);
void UARTConsolePutc(unsigned char data);
void UARTStdioInit();


int i=0;

void main(void) {

	UARTStdioInit();
	PINMUX11a=(PINMUX11a & ~ 0xFF000000) | 0x88000000;
	PINMUX12a=(PINMUX12a & ~ 0x0000000F) | 0x00000008;
	DIR45a = ~(0x03800000);

	OUT_DATA45a= (OUT_DATA45a + 0x03800000);
	UARTConsolePuts("Blinking LEDs\n\r");

while(1)
{

	OUT_DATA45a= (OUT_DATA45a + 0x03800000);
	for(i=100000000;i>0;i--);
}

}


void UARTConsolePuts(unsigned char *str)
{
	while(*str)
	   {
		UARTConsolePutc(*str++);
	   }

}

This code is working perfectly with ccs debug.

i am using ccs v5.2 and xds100v2.
