I recommend you to use a power supply and not a battery to power the board. If the battery is not powering succesfully the board and you have it connected to your PC, when the battery is not capable to power the board this one will use the energy from the USB port and may damage your board. So I recommend you to use a power supply instead of the battery.
To power your board you need first to plug the power supply and then connect the USB cable.
The issue that you are having seems to be related to the current and voltage that the board is receiving.
Hi, I need to use battery because I need portable power supply so the robot can carry it around (I'm making a robot). Also, at that time, I haven't connect Galileo to my computer yet, all I did was plugging in power from batteries, and waiting for the USB led to go on, then I have the permission to connect to my PC. Then here comes the problem, the USB led went on then went off soon after, then it seemed that the Galileo booted again from this point and the USB led continued going on and off.
In the FAQ section for Galileo boards ( Section-Power supplies) you would see the statement "..you must use a power supply at all times….If the board is not connected to a power supply when flashing, the board may fail or become unusable." I recommend you to use a power supply instead of the batteries.
Also, are you having the same behavior in the board when you power the board with a power supply or is it only with the battery?
I'm having this behaviour only when using the provided power adapter. Also, as I stated, my project will fail if I use the power adapter instead of batteries, because I need Galileo to carry its power supply around, which cannot be done if you use the power adapter.
Also, I've found the FAQ nothing useful information about this particular issue. In this link Arduino - IntelGalileoGen2, it says Galileo gen 2 can be supplied with voltage of 7V -12V, but in the FAQ section, it says Galileo cannot be powered by voltage greater than 5V.
How are you powering the board exactly? Are you using only a battery to power it or are you using the battery and the power supply as well? Which board do you have, Gen1 or Gen2? The Galileo Gen 1 board should be powered with 5V, but the Galileo Gen2 can be powered with 7V to 15V.
You can power the board with a battery but you have to make sure the battery is appropriate for that purpose.
I'm using Intel Galileo Gen 2. I powered the board by a power barred jack that is soldered to a 9V battery. And when I access the power of the board through the 5V pin for sensors, I'm unable to connect to my PC. That means the Usb led won't go on.
From your description I understand that the board works well before you connect the sensors. The cause might be the battery you are using. Did you try with another battery? You have to be careful because the board can be damaged.
Try to power the board with the power supply, not the battery, just to make sure what could be the cause of the issue. If the board works well with the sensors connected while it is powered with the power supply it would mean that the problem is the battery.
Hi, I've resolved this myself. I realized 9V was too little for the board, because I used 3 sensors at the same time. That's why the usb led didn't go on. Then I used more batterries up to a total of 13 V. Everything was great.
