    About it, I've never found a solution but I investigated a little.
    I had recently the occasion to speak with a NXP tech manager and he confirmed that all their architecture supposed to go to sleep and wakeup. Turning A9 into sleep will be awesome.
    @modjo , keep us updated if you find how.

    A9 deep sleep is working as discussed in the other thread , you just need to determine the wake up mechansim.

    Of course, I wasn't clear about that. The not trivial point seems to be the wake up in Udoo Neo.

    Thanks all for your messages. It seems that we can put the A9 in sleep mode and wake up it with GPIO or RTC ... Let you know if i make some progress ...
