FAQ: 

Q.  APS12 board will not execute application code when powered from barrel connector.

A.  When powering the board externally through the barrel connector, ensure a shunt is installed in the VR1 and VB postions.  Alternately, remove both option headers at BDM_EN. 

NOTE: The option headers at BDM_EN must be reinstalled in order to reestablish BDM communications.
