[1] Power consumption of the following parts is excluded:
*CAN PHY
*RS485 polarization network
*RS232 and RS485 are in shutdown mode
*Ethernet link
To configure the system to perform the deep-sleep mode, the following commands have been used.
* Enable wakeup from console:
<pre>
root@sbc-lynx:~# echo enabled > /sys/devices/soc0/soc.0/2000000.aips-bus/2000000.spba-bus/2020000.serial/tty/ttymxc0/power/wakeup
</pre>
* Enter suspend to memory, and wakeup from suspend:
<pre>
root@sbc-lynx:~# echo mem > /sys/power/state
PM: Syncing filesystems ...
