Hex file bulit by uvision4 not run on real board

Hi all,

I am studying ARM LPC2103 and try a simple delay code with timer 1

#include <lpc210x.h>
void set_up_PLL(void)
{
        PLLCFG=0x00000024;              //xtal=12Mhz, cclk=60Mhz => M=5, P=2
        PLLCON=0x00000003;              //PLL contected, PLL enabled
        PLLFEED=0x000000AA;
        PLLFEED=0x00000055;             //PLL feeded
        VPBDIV=0x000000002;             //pclk=1/2cclk
}
void set_up_timer1(void)
{
        T1CTCR=0x00000000;              //timer1 set as a timer, so T1CTCR[1:0]=00
        T1PR=0x00000009;                //Pclk devided by 10 when using for Timer1
        T1MR0=0x002DC6C0;               //T1MRO=3000000, after rising pulse, PC register increases by 1, when PC register reaches to 9
                                                        //which means that 10 rising pulses executed, PC register will be reset and TC will increase by 1
                                                        //when TC reaches to value in T1MR0=3000000 that means there would have been 30000000 pulses rose by
                                                        //pclk (similar with time of 1 second) there will be a event depending on set up of T1MCR register
        T1MCR=0x00000002;               //the event selected is to reset timer1 so T1MCR[2:0]=0b101;
}
void set_up_outputpin(void)
{
        PINSEL1=0x00000020;             // pin P0.19 is selected as MAT1.2
        T1EMR=0x00000300;               //after timer1 reset, pin MAT1.2 (P0.19) will be reversed bit, so T1EMR[5:4] should be 1:1
}
int main(void)
{
        set_up_PLL();                   //set up PLL so that cclk=60Mhz, pclk=30Mhz
        set_up_timer1();                //set up timer1 as timer to count Pclk rising pulses, after 1s, 1 event will reset timer 1
        set_up_outputpin();             //set up status of output pin when events generated by timer1
        T1TCR=0x00000002;               //reset timer1
        T1TCR=0X00000001;               //enable time1;
        while(1)
        {
        ;
        }

}

I built it without issue but when I run it on real board. It seem nothing executed. I don't know why. I think at least it run wrong result, it not able to do nothing like that.
Please help me solve issue.

Thanks and Best regards,
