How do I get the board to power up with an external power supply – 5 volts, without using the USB? I tried putting 5 volts into the boards 5 volt connector and that did not work, neither did it work after pressing the power button. I want to supply 5 volts to the P9 header 5Vdd pins and ground – so that the board runs independent of a USB connection.
What am I doing wrong??
