Faield to wakeup from suspend state

Products Support DragonBoard410c
#1

Hi,
I am trying to test suspend and wake-up functionality in dragon 410c board.
using
Linux linaro-alip 4.14.0-qcom-ifc6309-arm64 #2 SMP PREEMPT Mon Oct 29 19:20:34 IST 2018 aarch64 GNU/Linux
suspend is working with this command echo mem > /sys/power/state
After that trying to wake-up from suspend state is not working I have tried below methods

Enable configuration CONFIG_RTC_DRV_PL031
echo +10 > /sys/class/rtc/rtc0/wakealarm; echo mem > /sys/power/state
and Gpio interrupt based wakeup

both cases I can see heartbeat LED will start but no UART and UI

Please help me
Thank you

Hi Santosh,

Suspend/Resume is not a tested feature. It is probably some peripheral driver that needs fixing but it’ll need investigation.

If you’re interested in helping out, you could try to find out the buggy bits by referring to Documentation/power/s2ram.txt and file a bug.

Regards,
Amit

do you have any idea about this?

#5

We are getting similar kernel warning on wakeup. Any solution?

#6

If your kernel is 4.14.96, try the following patch. It fixed the issue related to screen not waking up.
