[beagleboard] BeagleBonewhite Power via Expansion header

2013-10-31 Thread Aravind V
I was trying to power the beaglebone white with the expansion header - 
connecting 12 in P9 to GND and 5 and 6 in P9 to 5V. All was fine till I 
connected the USB cable to the Beaglebone and it will no longer work. It 
died instantly and without any smoke/pop sound. What could be the reason. 
Is it a bad idea to power it via expansion header?

That should have worked. The only thing I can think of is that there may be
a grounding issue where the ground for the PC is different than the ground
of the power supply you are using for the 5V input on pins 5 and 6. Make
sure they are the same. Without looking at your schematic of how it is
hooked up, it is really hard to say what happened.
