Is it possible to burn the Beaglebone Black by wire two output pin?

Hi all

One of my mate has wired his Beaglebone Black two output GPIO pin together with a wire. He said it runs for a while. All the sudden his Beaglebone Black does not work any more.

The on board led only has one flash if he replug the power on.

Is it possible to break two output pins??

I am sure it can break the Beaglebone Black if one output pin connect to a input pin (both 3.3V)

Any idea?

My thanks

Robert

Yes. It is possible
