[beagleboard] RE: how can we tell system to shutdown on a power fail, using systemd and apcid
seems they omitted the "AC" interrupt in the patch https://patchwork.kernel.org/patch/9782813/ therefore the system will not power down on power fail like it used to -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

I think i see something interesting they did some changes to the dt for the pmic https://patchwork.kernel.org/patch/9771235/ some of the comments deal with interrupts seems the one that is missing or not handled is "AC" or something needs to be written to handle "AC" now I read something about breaking out the power button interrupt in some other verbage today as with the old kernel PB and AC fail did the same thing but to get AC fail to trigger a power off you needed apcid or at least it did not shut down till you installed acpid This is deeply buried in kernel land. might need to monitor a PG signal from the power supply and act on it with APCID till this is resolved At least if you do that you can set an interrupt with a powerfail gpio and write an APCID handler -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
