You send the board back to the factory in the US.

Help,
I just got an audio cape today and wanting to get it working I added it
to the top of the cape stack such that I had a beaglebone white, the
battery cape, dvi cape, and finally the new rev b audio cape on top. a
couple days ago I used this setup without the audio cape running on
batteries and it worked completely as expected. I plugged it into the
network and used the stack over ssh for over 3 hours as commented in a
previous post. Today, I was a bit short on batteries so after carefully
looking over the battery cape SRM found here
https://github.com/CircuitCo/BeagleBone-Battery/blob/master/BeagleBone-Battery-RevA-srm.pdf?raw=trueand
determining that it will accept from 1.8-5.5V across VBAT as
doccumented on page 16 of the cape SRM I reviewed the schematic to find J8
J9 allow attachment to VBATT such that I may attach a power supply to J8
or J9 for power. I then placed 2 AA cells in the battery holders on the
battery cape and measured the voltage across J8 J9 to determine proper
polarity after which I attached a black lead to the minus or negative
terminal and a red lead to the positive terminal. it blinked and flashed
nicely as I would wxpect at this point as if trying to boot. I then
attached a 5V power supply to these terminals checking for proper polarity
prior to turning on the supply which I measured at 5 volts. I only took
this option because after careful reading of the Battery cape SRM It stated
that 5v is in spec. well the board stack failed to come up or give any
indication of life, not so much as a power LED on any of the boards! then
about 15 seconds elapsed and things started to smell. I pulled power
shortly thereafter. now all that happens when I put batteries in the
battery cape in the batteries get too hot to hold in just a couple seconds
and the smell returns. trying to power the beaglebone over USB with no
other capes attached blinks the power LED but no other evidence of life is
seen. I am also suspect of the audio cape and dvi cape possibly being
fried as well. are there some additional things I can and should check or
is this something for direct RMA?
Thanks,
Eric
