Hi,
when i suspend my 2G IOT (with Ubuntu 16.04.1) by
  1. sudo systemctl suspend
Copy the Code
it always wakes up automaticly after few seconds.


I have tried to pull-down the signal from button by resistor with no effect.
So i thing that there is some software interupt.

Do you know what wakes up the orangepi from suspend?

Thanks, Radim

In file "/sys/kernel/debug/wakeup_sources" i have found some counters are incremented when it wake up.
Wake up by button: mmc1_detect, mmc0_detect and rda-keypad are incremented
Wake up spontaneously: mmc1_detect, mmc0_detect and battery are incremented

So it looks some battery flag wake it up. Any hint how to repare it?
I have no battery connected - only power by USB.
I have tried to pull-down and pull-up the third battery pad but with no effect.
