UDOO board has a possibility to disable most of imx6 SoC power supplies via "EN_5V" signal, which is connected to "NANDF_D4" pad. This reduces current consumption after shutdown from ~350 mA to ~40 mA and prevents a SoC watchdog from starting it again on its own after the watchdog timeout expires (previously it was not possible to shut down the SoC permanently if its watchdog was ever enabled since it was still ticking after the shutdown). Unfortunately, this does not extinguish the "Power" LED (as it is powered from an always-on voltage regulator). To power the SoC up again press the power button (SW2, the one with a long shaft).
