Lpc2000

Hi everybody,

I am currently working on the mcb2140 with LPC2148.

I am facing problem in uploading to the board using philips lpc2000 
flash utility. The code works well when simulated using the keil 
software. 

When i am trying to load to the board, an error message pop up: 

run-time error '8015' could not set comm state, there may be one or 
more invalid communications parameters.

The code can be uploaded successfully if i am using uart1 as a 
replacement to the uart0 in my code below..

Anyone have any idea on how to fix the problem?

Below is my code:
#include<LPC214x.h>
#include<stdio.h>

void UART0_Init(void);
void UART0_Write(char);

void main()
{
int i;
char s[]="Hello World!\n";

UART0_Init();

while(1)
{
i=0;
while (s[i]!= '\0')
{
UART0_Write(s[i]);
i++;
}
}
}
void UART0_Init(void)
{

PINSEL0=0x05; 
U0LCR=0x83; 
U0DLL=97;
U0LCR=0x03;
}

void UART0_Write(char c)
{
while(!(U0LSR & 0x20)); 
U0THR=c;
}

Thanks
