Hi
I try to set an GPIO Port ( P1_15 ) to high, but it does not work. I 
used the MCB1800 Board with an LPC1857 and modified the Blinky Example.

Somebody has an idea?

Code:
 
#include "board.h"
#include <stdio.h>
#include "stopwatch.h"

/****************************************************************************/
void SysTick_Handler(void)
{
  static int x = 0;
  if (x++ > 500) {
    Board_LED_Toggle(0);
    x = 0;
  }
}

/****************************************************************************/

int main(void)
{

  SystemCoreClockUpdate();
  Board_Init();
        Chip_GPIO_Init(LPC_GPIO_PORT);
        Chip_GPIO_SetPinDIROutput(LPC_GPIO_PORT, 1, 15);
        Chip_GPIO_SetPinOutHigh (LPC_GPIO_PORT, 1, 15);

        
  /* Enable and setup SysTick Timer at a periodic rate */
  SysTick_Config(SystemCoreClock / TICKRATE_HZ1);
        


  while (1) {
    __WFI();
  }

  return 0;
}
