Has anybody try out ACPI WakeUp with the Up Squared?
I don't manage to get the ACPI WakeUp working under easyVDR 3.0 (Linux easyVDR 4.4.0-93-generic #116~14.04.1-Ubuntu SMP) ...

    [email protected]:/# sudo sh -c "echo `date '+%s' -d '+ 3 minutes'` > /sys/class/rtc/rtc0/wakealarm"
    [email protected]:/# cat /proc/driver/rtc

    The same with "hpet=disable" as kernel Parameter, no ACPI WakeUp. :(

    Forgives my bad english!
    Yet another try under 4.9.45-ubilinux+.
    Please, can somebody try the following in a root terminal?
    sudo rtcwake -m no -s 60 && sudo poweroff
    The system should "poweroff" and wakeup after roughly 60 seconds, theoretical...

    ACPI Wake is essential for me because I want to use the UP Squared as a VDR (VideoDiskRecorder [easyVDR])!

    Thanks a lot!!

    Did you enable RTC wake function in your BIOS? If not, please try it and set to dynamic Time mode, and set 1 for wake up minute incr as bleow

    Bios path for boot option: Advanced --> Power Management

    If I set "RTC wake system from [Dynamic Time]" to 1 the system powered up after 1 minute.
    "RTC wake system from [Static Time]" works also.
    But the problem is to set the wake up time by linux's ACPI Wakeup.
    Under Ubilinux RTC wake BIOS funktion is disabled.
