Hello BeagleBoard community,

I'm afraid I bricked my Beaglebone Black.

The current symptom: Upon being connected to power (either from the DC jack 
or USB), the power LED blinks briefly, and then goes out.  And... that's 
it.  No other LED's or other indicators, and no boot sequence.  It's the 
same whether there's an SD card present or not; the system never even gets 
that far.

Help?  Here's what I was doing at the time:

- I was attempting to read the GPIO state of one of the pins (P9.11, 
gpio0[30]).
- I connected this pin to +3.3V (P9.3).
- I executed cat /sys/class/gpio/gpio30/value (GPIO 30 is the system name 
for this pin) a number of times.

I had previously used this pin as a GPIO "out" (reading its value) without 
a problem.  I figured that means it was "safe" to use as a GPIO "in".  What 
else might this have done?

Thanks to all.

-Jason
