It seems PWM3 is also taken, by the vibrator? I noticed all PWM outputs were used and then decided since PWM3 also drives the FIQ voodoo, which I didn't want to go deep into, I'd have less issues colliding with just a LED when testing. Note that on GTA02 the patch only uses pwm4 and optionally the watchdog. Cheers, Andrew
