The board is connected to a 5V power supply, to a USB hub and via Ethernet to a router. It has no capes.
uname -a Linux beaglebone 4.4.39-ti-r75 #1 SMP Thu Dec 15 22:16:11 UTC 2016 armv7l GNU/Linux The command sudo systemctl poweroff reboots it just like shutdown -P now However, if the board is disconnected from the USB hub (still connected to the power supply), both of the above commands shut the unit down as expected. I checked this several times: connecting even a running unit to USB makes it unable to shutdown. However, if powered from USB (power supply disconnected) the board shuts down again without a problem. I tested this several times and it seems, that the only combination where the board can not shut down is when connected to both the power supply and USB at once. Which is ok as of me, as I do not need the USB connection any more. There is an old thread (the kernel must obviously have been different) where a similar problem is reported by several people: https://groups.google.com/forum/#!msg/beagleboard/qw5zlS4F4p4/chu0J3VXKgAJ On Wednesday, April 26, 2017 at 4:45:41 AM UTC+2, Graham wrote: > > What OS/kernel is ithinu running? > > "shutdown -P now" works on all my BBB/BBG boards. > > But, I run from external +5V, without anything on the battery connections. > > --- Graham > > == > > >> I usually tell everyone to use: >> >> sudo systemctl poweroff >> >> as systemd knows how to tell the external tps65217 to cut power. >> >> looking at the syslog, i don't remember any issues with 4.4.39-ti-r75, >> and looking at the git log i don't see any poweroff regressions >> mentioned.. >> >> Regards, >> >> -- >> Robert Nelson >> https://rcn-ee.com/ >> >> -- >> For more options, visit http://beagleboard.org/discuss >> --- >> You received this message because you are subscribed to a topic in the >> Google Groups "BeagleBoard" group. >> To unsubscribe from this topic, visit >> https://groups.google.com/d/topic/beagleboard/9VdtZKf3Dz0/unsubscribe. >> To unsubscribe from this group and all its topics, send an email to >> [email protected] <javascript:>. >> To view this discussion on the web visit >> https://groups.google.com/d/msgid/beagleboard/CAOCHtYgHtwySLzoGJOdRLwGKm34kPxxwz6GBj5BFwWYUUtbR9g%40mail.gmail.com >> . >> For more options, visit https://groups.google.com/d/optout. >> > > -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
