Suspend to RAM

This state offers significant power savings as everything in the system is put into a low-power state, except for memory, which is placed into the self-refresh mode to retain its contents.

To suspend to RAM:

$ echo mem > /sys/power/state

To wake up:
There are a few ways to wake up from suspend.
For example, using the RTC you can wake at a specific time (see the RTC section).
Another way is to push a button on the board which is set as wakeable.

Current consumption when suspended

VAR-SOM-MX6 "L" revisions (1GB RAM)

17.2mA with a 3.7V Li-Po

Warning: Only "L" (for Low-power) revisions of VAR-SOM-MX6 can be operated with 3.7V!

DART-MX6

9mA with a 3.7V Li-Po

VAR-DART-6UL

4.5mA with 3.3V
