Does the Galileo board support automatic power selection or PWR_SEL jumper to draw power from Shield's power source?

Does the Galileo board support automatic power selection or PWR_SEL jumper to draw power from Shiled's power source, instead of power supply cable? Thanks.

As far as I understand the Galileo Datasheet (/servlet/JiveServlet/downloadBody/21835-102-4-25148/Galileo_Datasheet_329681_003.pdf https://communities.intel.com/servlet/JiveServlet/downloadBody/21835-102-4-25148/Galileo_Datasheet_3...), Galileo doesn't support any form of drawing the power from shields, there are quite a few warnings all across the docs that one must have the power adapter connected at all times.

That's my understanding, those with more knowledge are welcome to chime in.

I was offline for vacation. You're right, the pdf does give the warning. Anyone tried to power the board by reworking the power cable to connect to battery pack (4xAA)?

I personally haven't tried that, but chofrock mentioned such a use in /thread/47188 this thread

, care to share some details or a link to a discussion on that, if you have it somewhere?

I have not personally tried connecting AA batteries to the Galileo. I have talked to people who have, and they mentioned that the sketch only continued to run for about 15 minutes.

I would not recommend anyone trying to run off of batteries unless you have a Dediprog in order to reprogram the SPI firmware.

Thanks for sharing! Alternative could probably be an auto-shutdown watchdog, which would power down the board after battery pack gets below certain voltage.
