Reynard 0 Report post Posted April 23, 2008 Do you have the watchdog timer disabled ? It's enabled by default usually. Do you have a loop somewhere to stop main() falling out of the bottom. You need to give us all a few more clues to what you have done or not done. Cheers Reynard Quote Share this post Link to post Share on other sites
