Mark,
Changing the EXTERNAL_CLOCK and _EXTERNAL_CLOCK #defines did not seem to work. There is an LED and I set the GREEN_LED to the port and pin for our board (#define GREEN_LED (PORTD_BIT15) ) and updated TOGGLE_WATCHDOG_LED() with _TOGGLE_PORT(D, BLINK_LED). Blink LED is set to GREEN_LED. The LED did not blink after programming and cycling power.
We have a project built for the board so I know the USB works. I also verified the proper capacitor are on VOUT33 (2.2uF) and 3.3V on VREGIN that you mentioned earlier.
Is there anything else you can think of that I may have missed?
Thanks,
Randy
