I really think you did something else wrong. Especially if it happened multiple times: I can imagine that it happens once if there is a production error in the PCB (although still then it is unlikely you burn out anything besides the voltage regulator), but several times?

There is no direct connection between the reset pin and the LPC1768, it even goes via a different IC. And for that IC it is just an input pin. Even if it would accidently be set as high output it still wouldn't cause your IC to burn down.
