Hello,

Ho to let BBB standby and wake up by pressing power button ?
I want to make a hand held device using BBB with Li-ion battery
and I want power button acts like smart phone device does.

Now I’m using :

Android : TI-Android-JB-4.2.2-DevKit-4.1.1

Kernel : linux-3.2.0

Thank you very much.

Won’t be possible until PMIC subsystem is fixed which I’m told is scheduled for V3.19.

Hello John,

Thanks for your reply.

I consider to use additional hardware to carry out power on/off the board.

Please let me know if you have any solution.

Best Regards

You can power off the beaglebone by holding the power button for about 4 seconds
Clicking it after will power it back up.

Many thanks for your comments.

Problem solved.

How lucky am I !

I’ve followed the bellow link, modified the kernel source and it can work properly.
