I'm trying to bring up a custom board based on the ADuCM350. I've modified the blinky application to toggle P1.1 and P2.7 which is where my LEDs are, however I'm not seeing the pins toggle. If I run the same application on the EVK I do see those pins toggling at the Digital Header connector. Toggling P4.0 and P4.1 on the custom board also works.
Is there a separate voltage rail for P1 and P2 vs P4 that I didn't power? What could be wrong?
