Hello,
I am trying to get wakeup of my HTPC set up. Following the exessive guidline from the MythTV wiki, I am already stuck at the first stages.
It seems that I cannot write to the SysFS file properly, but it does also not yield an error.
Whatever I want to echo into the wakealarm file, I only see that it updates the alarm_time with a short offset from now:
Code
Libreelec# echo 0 > /sys/class/rtc/rtc0/wakealarm
Libreelec# cat /proc/driver/rtc
rtc_time : 09:18:50
rtc_date : 2017-04-01
alrm_time : 09:23:43
alrm_date : 2017-04-01
alarm_IRQ : no
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

The alarm_IRQ is not set, which means the box won't wake up.
Regardless of which epoch time I echo into the wakealarm file, it is always the same result. I only have a few minutes offset from the rtc_time and no IRQ.
What would be my next step to investigate?
Thank you.
Regards,
Marcus
