Beagleboard xm rev A3 does not respond

Hi, There my beagle board is doing the exact same thing did you ever figure out your issue?

Hi there,

If memory serves me correctly, some of the rev A boards had reverse polarity on DC power Jack +(- instead of the regular -(+. If you are using one of those boards and put an external dc power supply with correct polarity then it usually fries the power switch regulator (responsible of switching power from either DC or USB and over voltage protection)

There are test points on the board that you can check the voltage to see if power is even coming past the regulators.

Good Luck


News to me.
