Hi

We are trying to wake up RTC from state S5 of ACPI using i.Mx7D to seve power.
At that time, I tried setting alarm_time with the following command on the console, but it does not start up.
Can you tell me if there are any procedures?
------------------------------
root @ imx 7 dsabresd: ~ # date '+% s' - d '+ 5 minutes'> / sys / class / rtc / rtc 0 / wakealarm
root @ imx 7 dsabresd: ~ # cat / proc / driver / rtc
rtc_time: 15: 14: 13
rtc_date: 2018 - 10 - 09
alrm_time: 15: 19: 08
alrm_date: 2018-10-09
alarm_IRQ: yes
alrm_pending: no
update IRQ enabled: no
periodic IRQ enabled: no
periodic IRQ frequency: 1
max user IRQ frequency: 64
24hr: yes
root @ imx 7 dsabresd: ~ # shutdown - h now
------------------------------

Thank you
