Lpc2000

Hello Friends,
 
                       I have written IAP to read PART IDENTIFICATION NUMBER for LPC2129. I am using ULINK to burn firmware and want to display part ID on hyperterminal ...but unable to get succed ..am I doing error in my code ...
 
#include <stdio.h>
#include <LPC21xx.H>
 
struct iap_non_volatile 
{
  unsigned int cammand;       
  unsigned int parameter[4];  
};
 
typedef void (*IAP)(struct iap_non_volatile *in, unsigned int *result);
#define iap_entry ((IAP) 0x7FFFFFF1)             // IAP entry point
 
 struct iap_non_volatile  iap; 
 
void main (void)
{
unsigned int volatile start;
for (start = 0; start < 1000000; start++) 
 {
    ;     // wait for debugger connection (about 0.3 sec)
 }        
 
while(1)
  { 
    iap.cammand = 54;
    iap_entry (&iap, result);
    puthex_word(result);
}
}
 
 
It is possible to burn firmware using ULINK and read ID using COM port.....Do I have to enter in debug mode ?? when I open my hypertermal windows and try to establish communication ....the code hands up ......I am using keil CARM 
 
Please help me guys 
 
With regards,
 
Sridhar
