BBB Board not turning ON using 5V-2A DC power supply.

Hello All,

Since I bought a BBB board I was using it using USB power supply. Today I tried to connect the external power supply of 5V 2A ratings.
And board is not turning ON. Power LED is also not turning on.
Where as if I will connect USB supply, board will turn ON and I can login over SSH connection.

Please give the hints to start with debugging.

try another 5v supply

Incorrect polarity on supply connector?

that might let the magic smoke out

You mean the board doesn't have a 5 cents reverse polarity protection diode?:hushed:
