Hi, I'm trying to suspend/resume my BBB based on GPIO input. I'm using Kernel 3.14.29-ti-r46 and suspending with "echo mem > /sys/power/state" works. I can also wake up the BBB via the serial console. From what I found on the internet it should be possible to wake the BBB also from GPIO0, but a level change on GPIO0_x (I tried 7 and 26) doesn't show any effect. Does anybody know what I need to configure to wake up the BBB from GPIO?
