The same test bed described in the [[#Idle configurations|Idle configuration]] section has been used.

Then ''deep-sleep mode'' has been enabled by issuing the following commandcommands:<pre>echo enabled > /sys/devices/soc0/soc.0/2000000.aips-bus/2000000.spba-bus/2020000.serial/tty/ttymxc0/power/wakeuproot@sbc-lynx:~# echo mem > /sys/power/state</pre>The first command is used to enable the console UART as wake up source. The following table recaps the power consumptions measured under this condition.{|class="wikitable" style="text-align: center;"|-!Board power consumption ([[#PSUBlockDiagram|probe #1]]) [1]<br>[mW]!Processor subsystem power consumption ([[#PSUBlockDiagram|probe #2]]) [1]<br>[mW]|-| 57||47|-|}[1] When entering DSM mode, iMX6UL turns 24MHz external active oscillator off. As the board under test is equipped with iMX6UL revision 1.0, active oscillator is required to implement the fix described by errata ERR009455. For more details please refer to ''Chip Errata for the i.MX 6UltraLite''<ref name="IMX6ULCE">Freescale Semiconductor, ''Chip Errata for the i.MX 6UltraLite'', Rev. 0.1, 02/2016</ref>. [2] Ethernet PHY supports several power-management modes. The most aggressive is the ''slow-oscillator mode''. At the time of this writing, Linux kernel does not support this mode. The ''power-down mode'' is used instead. If ''slow-oscillator mode'' were implemented, about 7mW would be spared.
