Re: NEED SOME HELP with a DEAD STAR WARS BOARDSET....

Right. A correctly functioning watchdog circuit only *pulses*
the RESET line, then watches again, and pulses again, if
necessary. On a bad board with a good watchdog, it does
this: ~~~~~_~~~~~_~~~~~_~~~~~_~~~~~ etc.

RESET stuck low is almost certainly due to a bad watchdog
circuit. If you don't have schematics, or you can't read them,
maybe someone here can help.

By they way, have you made sure the reset *button* isn't "stuck
low"? ;-)
