How to resume from suspend to ram

[inajob]

I use Debian of 202303.

I can suspend VisionFive2 with below command.

echo mem > /sys/power/state

And wake up from RTC event with below command.

echo +60 > /sys/class/rtc/rtc0/wakealarm

But I don’t know how to wakeup from other sources(GPIO or USB Keyboard …).

I haven’t dealt with that yet, but I guess this helps:

Difference between suspend by echo "mem" > /sys/power/state and by suspend in XFCE?

[inajob]

I executed systemctl suspend, but it is as same as echo "mem" > /sys/power/state.
My board can’t wake up by USB Keyboard.

Have you already looked in here?

Swsusp on VF2

Hi, dear community, as I knew it before, at some point a CONFIG_PM was finally enabled and both Hibernation and Suspend features are available. I’m more interested in Hibernation rather than Suspend (store to RAM and maintain), because that’s what my working pattern with personal general purpose computers I own. I tried to hibernate an SSH only controlled board by issuing command from serial. For some unknown reason, I was asked to put MAJOR:MINOR numbers of swap partition instead of it’s name…

It may be about hibernation.
My problem is suspend.

If someone know the way to suspend/wakeup(from USB Keyboard or GPIO), please let me know.

Wake up from suspend using wireless USB keyboard or mouse (for any Linux Distro)

I tried this(like below), but my board can’t wake up by USB Keyboard.

echo enable > /sys/bus/usb/devices/usb1/power/wakeup (for each devices)
