keil uvision5 hex problem

You wouldn't be using the free Evaluation - or "Lite" - version, would you?

I seem to remember that older Evaluation versions used to insert a load of dummy padding ...

Yes I am using Lite version

This is the basic Led blinking program i am using

The hex file created for this program in Uv4 is running fine and I am getting the output

While the hex file for same program in Uv5 is not running properly I am not getting anything as output the Leds are not blinking

#include <LPC214X.H>

void delay_ms(unsigned int);
int main()
{

VPBDIV = 0X00; //PERIPHERAL CLOCK FREQ = 15MHZ IO0DIR = 0X00FF0000; // SET PORT DIRECTION I/O PINSEL1 = 0X00000000; // PORT PIN CONFIGURATION AS A GPIO (P0.16 TO P0.31)

while(1) {

IO0SET = 0X00FF0000; delay_ms(2000); IO0CLR = 0X00FF0000; delay_ms(2000); }

}
void delay_ms(unsigned int value )
{ unsigned int i; value = value * 15000; for(i=0;i<value;i++);
}

1) That's a tiny program, so why expect a large hex file?

2) Your source file is uart.c. But the source code doesn't seem to relate to any UART.

3) Are you sure you have any LED on the specific pins?

4) How have you verified that the program gets downloaded correctly?

5) How have you verified what happens on the relevant port pins?

6) How do you know if the processor leaves the reset state?

7) How do you know the processor doesn't stays in the boot loader?

8) Have you verified all project settings?

9) Any other observations you have made, that is actually relevant to your problem and not related to your assumptions about size of produced hex file?
