I measured the current (DC jack powered) my BBB (rev C, kernel v3.16.3) draws at idle: ~200mA. Then I issued a *poweroff* (or *shutdown now*) command, and after the system had halted I measured current draw at ~240mA. This is a bare BBB with nothing attached (besides the serial debug cable). This isn't what I expected to happen.
Holding the power button for 8 seconds does power off the BBB (<1mA). However, I find the method of "hold for >=8 seconds, but not >=8.5 seconds or else it power cycles" to be kind of user-unfriendly. Is there a way to programmatically put the BBB into the same state as holding the power button for 8 seconds? I've done a bit of searching and it looks like there were problems (from earlier in the year) with the PMIC/RTC and bringing the board down to a low-power state from software alone. I just wanted to ask if those problems had been resolved. I tried doing a *echo mem > /sys/power/state* which returned Invalid argument. Note that I'd like to try both methods: software command the BBB to power down as if the power button had been held for 8 seconds, as well as a memory-saving/restoring state. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
