Hi Programming the LPC210x at 60MHz didn't cause a problem - it seems to work fine. We did make a mistake in passing the PCLK (1/4 in this case) instead of the CLOCK as parameter (in kHz). The effect was that the FLASH was not programmed long enough and so the data was not reliable. Typically the board would work fine after power up but after a reset it wouldn't start because a check sum run across the program code would signal an error. After this silly mistake all has been stable. Regards Mark Butcher www.mjbc.ch > So, it just proof the old classic, never trust a Philips Datasheet ! > > /Jesper
