You trimmed the critical sentence "It worked and ***after connecting a 
wiggler with the connector upside down*** exibihts this strange behaviour."

Sounds like his board was damaged by operator error (improperly 
connecting to the BDI connector).  My guess is that the pullup resistor 
lost its smoke.
