no ACPI WakeUp

test.it

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) ...

Hi test

This function need the kernel 4.6 or above to support that

test.it

So i try it with ubilinux
root@ubilinux4:/# uname -r 4.9.45-ubilinux+
and a simple wakeup test
Wake Up Linux With an RTC Alarm Clock

root@ubilinux4:/# sudo sh -c "echo 0 > /sys/class/rtc/rtc0/wakealarm"
root@ubilinux4:/# sudo sh -c "echo `date '+%s' -d '+ 3 minutes'` > /sys/class/rtc/rtc0/wakealarm"
root@ubilinux4:/# cat /proc/driver/rtc

Spoiler

rtc_time : 21:09:04
rtc_date : 2017-12-21
alrm_time : 21:11:30
alrm_date : 2017-12-21
alarm_IRQ : yes
alrm_pending : no
update IRQ enabled : no
periodic IRQ enabled : no
periodic IRQ frequency : 1024
max user IRQ frequency : 64
24hr : yes
periodic_IRQ : no
update_IRQ : no
HPET_emulated : yes
BCD : yes
DST_enable : no
periodic_freq : 1024
batt_status : okay

root@ubilinux4:/# shutdown -P now

The board dont comes back up in ~3 minutes!!!

test.it

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

test.it

Forgives my bad english!
Yet another try under 4.9.45-ubilinux+.
NO ACPi WAKEUP!
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

test.it

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.

Something is going on... after over a year ago
