vilaemail posted a topic in Allwinner A20Hi folks, I am trying for couple of days now to put Lime1 to sleep and then wake it up, both by software and user interaction. Problem description: I am able to put board to sleep with any of the following commands: rtcwake -m standby -s 10 echo "standby" > /sys/power/state When device is on battery I can see it consuming ~0.7A while it works normally and once i execute one of the above commands it drops down to about ~0.25A leading me to conclusion that device has indeed in sleep. Here is how I ran rtcwake to make sure RTC clock is up and running: root@lime:/etc/systemd/system# hwclock -w root@lime:/etc/systemd/system# hwclock Mon 10 Sep 2018 08:21:03 PM UTC .218585 seconds root@lime:/etc/systemd/system# hwclock Mon 10 Sep 2018 08:21:09 PM UTC .338408 seconds root@lime:/etc/systemd/system# sudo rtcwake -m standby -s 10 rtcwake: wakeup from "standby" using /dev/rtc0 at Mon Sep 10 20:21:39 2018 Once device is in sleep, I am not able to wake it up no matter what I do, only way to "recover" the device is to long press power button until it turns off (hard shutdown) (this happens with both rtcwake and /sys/power/state), then release and long press again to turn it on. What have I tried: I fiddled around with script.fex file to no avail. What I am using at the moment for pmu part is below (if you need other sections I can send them on, wanted to keep the post short...) System information: A20 processor on A10-OlinuXino-Lime Rev.E board without eMMC. Downloaded and using "Desktop" image from https://www.armbian.com/olimex-lime/ U-Boot SPL 2017.11-armbian (Jan 25 2018 - 01:01:48) root@lime:~# uname -a Linux lime 3.4.113-sun7i #16 SMP PREEMPT Wed Jan 24 19:20:59 CET 2018 armv7l armv7l armv7l GNU/Linux root@lime:~# cat /etc/os-release NAME="Ubuntu" VERSION="16.04.5 LTS (Xenial Xerus)" Any idea what can I do to somehow wake up the device? Any other info I can provide? Thanks for any help you can provide.
