Sleep modes in Orange Pi zero

Ansic

Is there any sleep modes in Orange Pi Zero?
I Searched alot for this but could not found any good information regarding sleep mode.
Actually I have to schedule task. So, Pi Zero should soft wake up from sleep mode do its task and then again go to sleep.

Yes, there are sleep modes. Check the file

1. /sys/power/state

Copy code

It should contain

1. freeze mem disk

Copy code

indicating, that power management is working. If you want to suspend your system to RAM you can do so by writing mem to that file:

1. ed@257EE39E:~$ echo mem | sudo tee /sys/power/state
   
2. Password:
   
3. mem
