I am working with the lpcexpresso board 1549. The examples from the 1549 zip archive worked without any problems.
I created a project which only relies on the lpc_chip_15xx library.

Some GPIO pins don't work as expected when I want to blink the red on board led always the green on board led and
a led connected to PIO0_0 D7 ( Arduino Header) is blinking.

What is wrong wih my code ?

while(1)
      {
      ticks = sysTickCnt;
      ticks += 100;
      while(ticks > sysTickCnt);
      Chip_GPIO_SetPortToggle(LPC_GPIO, bled[red].port, bled[red].pin);

Why :quest: The better solution is to copy LPCXpresso board library and change it :)

Anyway, without posting your project(s) it's difficult to debug...
