Alright that would make sense. Is there any way I can correct the code to account for the changed circuit?

Its possible that the existing LED was connected between Vcc and the pin ( via a resistor) and have wired your LED from the GPIO to Gnd.

If the top layer of the PCB had a copper plane that was Vcc, then for surface mount devices, connecting from that Vcc plane to the LED would save 1 via hole.

I am positive that I made no changes other than the pin number. One thing to note is that originally it wasn't an open GPIO pin but an led that is already soldered onto the board. It is just controlled like a GPIO pin. Is it possible that the signal is inverted for the on board LED? Also we are using an old version of the SDK because we were following an example that was using it.

This seems unlikely, all the GPIO pins behave the same.

Are you sure the code does not have any other changes?

BTW. Why are you using such and old version of the SDK ?
