I'm trying to use an external button to control power on/off on BBB. I currently have a momentary button wired to pwr_btn and pulled up high via 3.3V pin. The issue is that 3.3v is not enabled by default in sleep mode. I have no problem pressing the button to pull ground and shut down the beaglebone, but then when it goes to sleep, 3.3v (LDO2) rail shuts off which pulls the pwr_but ground which then immediately triggers power on again.
How would I enable LDO2 in sleep mode? I read through the user guild (http://www.ti.com/lit/ds/symlink/tps65217c.pdf) and couldn't find any answers. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
