M2A wakeup

Moderators: chensy, FATechsupport

Hi,

how to wake up M2A from suspend mode ?
PWR button don't wakeup my M2A. :roll:
Is this hardware problem or FA software/kernel don't support wakeup?
Hi,
M2A has AXP228 chip, support software shutdown and wake up sleep.
What system do you use?

Thanks!
Hi,

i'm using S5P4418-ubuntu-core-qt4-sd4g-20170414 and tested S5P4418-debian-sd4g-20170414 too.
I have installed pm-utils and used pm-suspend command. Maybe i do something wrong and should put M2A into
suspend to ram mode in another way ? How ?

I want to use PWRKEY, internal RTC (battery is connected) or/and Alive PIN to wake up this board.

Thanks,
Hi,

i have made some tests and i must say suspend and wake-up don't work correctly.
"suspend_valid: not supported state"

Tested on S5P4418-ubuntu-core-qt4-sd4g-20170414

It seems like kernel or some drivers are not right configured for suspend and wake-up.
