Hi Sina,

serial

check if P0.14 is tied to ground correctly for serial programming. The
serial PC download tool writes a checksum to flash memory to signal the
boot ROM software that there is software available that can be started.
At the very first time on a fresh LPC this checksum is not there and the
serial ROM loader is started - regardless of the P0.14 pin.
