Re: [beagleboard] BeagleBone Black powers down when AC adapter is removed while the USB is connected.
Sorry to revive an old thread but I wanted to add my solution to this problem somewhere and this seems like the most appropriate place to do it. I was also experiencing the Bone shutting itself down on AC Power removal regardless of a battery present. The logs showed it was registering the removal as a button press condition and powering down the unit. I had a product running on 4.1.19-bone20 and did not want to update to a later kernel but it appears to be resolved in later kernels already. To fix on 4.1.19-bone20, I modified the file mentioned here (/drivers/mfd/tps65217.c) and commented out this code entirely: /* if (int_reg & TPS65217_INT_ACI) { /* Handle AC power status change dev_dbg(tps->dev, "AC power status change\n"); /* Press KEY_POWER when AC not present input_report_key(tps->pwr_but, KEY_POWER, ~status_reg & TPS65217_STATUS_ACPWR); input_sync(tps->pwr_but); } */ After I rebuilt and deployed the modified kernel, the problem was resolved, no more power down on AC removal. For anyone who needs further instructions, I'd be happy to help.

Yeah, you probably mean this: https://plus.google.com/+DrewFustini/posts/jUkFsbVJVHQ Apart from some highly regarded bb'ners advising against it I'm not looking for battery backup. I'm looking for easy automatic clean shutdown (aka eacs). In the plc world they're using a super capacitor to do the clean shutdown (and save some data to flash). I was hoping that with power supplied to the usb otg port I had an easy solution. Now it seems I have to make a momentary switch to short pwr_but for lees than 8 sec. or program a gpio to shut down the bbb when power is removed. Unless I understand why the bbb is shutting down clean with usb otg connected to pc but not when usb otg connected to a battery.

RE: [beagleboard] BeagleBone Black powers down when AC adapter is removed while the USB is connected.
There is a signal, on P9 I believe, called “power”. If you pull this pin low with a pushbutton switch, you will get the clean shutdown you are looking for.

I guess a rebuild is in order, I did the same test with Debian and saw the same result, except that with Debian a message is posted to the console explaining that shutdown is occurring due to loss of AC power On Tuesday, November 18, 2014 1:57:47 PM UTC-5, Gerald wrote: > > Then the SW needs to be changed to change that behavior. > > Gerald > > > On Tue, Nov 18, 2014 at 10:37 AM, David Hirst > wrote: > >> The fact that it powers down is a problem to me, if for instance a slight >> power interruption occurs ( lets say 5 seconds) during which time the CPU >> is powered by the battery backup I would like to carry on running, if its >> longer then I would like to make the decision when to shutdown. >> As it stands now I have no option but to have the system power down. >> With the current implementation In the event of a small interruption, the >> system will start to power down but if that the power has now returned >> prior to the shutdown occurring the system needs intervention to power >> back up, by power cycling either the USB or AC.

Re: [beagleboard] BeagleBone Black powers down when AC adapter is removed while the USB is connected.
The fact that it powers down is a problem to me, if for instance a slight power interruption occurs ( lets say 5 seconds) during which time the CPU is powered by the battery backup I would like to carry on running, if its longer then I would like to make the decision when to shutdown. As it stands now I have no option but to have the system power down. With the current implementation In the event of a small interruption, the system will start to power down but if that the power has now returned prior to the shutdown occurring the system needs intervention to power back up, by power cycling either the USB or AC. I want to smooth out short power cycles and let the long power outages re-power the board when the power returns On Monday, November 17, 2014 10:04:21 AM UTC-5, Gerald wrote: > > That should be bale to be fixed by changing the behavior of the SW.

That should be bale to be fixed by changing the behavior of the SW. You can look at the datasheet for the TPS65217C to see what registers to change.

Re: [beagleboard] BeagleBone Black powers down when AC adapter is removed while the USB is connected.
Attn Gerald Coley, Hello, In order to avoid any misunderstanding, I wrote "I had a similar problem". But I didn't use the USB connection. Only 5V DC and battery were connected to the BBB. As soon as 5V DC PS was off, the Debian LXDE version was shutting down but a warning was appearing telling the user the system was shutting down within 60s if this procedure wasn't canceled. Maybe David Hirst's problem is related to the same software "mecanism". Kind regards Michel. 2014-11-17 12:31 GMT+01:00 Gerald Coley : > Interesting.

Re: [beagleboard] BeagleBone Black powers down when AC adapter is removed while the USB is connected.
There is a previous thread, several weeks ago about this same behavior. That thread involved an application that ran off mains but had battery backup and everytime mains failed, and 5V goes away, the BBB shutdown. IIRC, this is a known software default behavior when the 5V goes away, it is programmable and needs to be set accordingly to how the end user whats it to behave. -david .

RE: [beagleboard] BeagleBone Black powers down when AC adapter is removed while the USB is connected.
As far as I know, it shouldn’t do that. The USB should provide power if the AC (+5v) is removed. What else is connected to the BBB ?

[beagleboard] BeagleBone Black powers down when AC adapter is removed while the USB is connected.
I am trying to manage power myself including battery backup, however if I have USB power and AC adapter power whenever I disconnect the AC power, the system shuts down shortly after. I would like to manage the shutdown myself. Can anyone tell me how to disable the default control Thanks -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
