    Q: condiction:
    1.the supply is powered by the 5V adapter-OK
    2. the OMAPL138 has been plugged in the baseboard
    3.without anyother connection
    Phenomenon:
    1.D5 doesn't light(3.3V-1.8V OFF)
    2.R169 is low

     

    A:

    1. D5 should light up with or without the SOM properly seated.

    2. R169 should be otherwise you would be asserting reset.

    Are you seeing any output on the terminal?
