First of all, I try the “sudo systemctl suspend” command, but I get Error like this “Failed to suspend system via logind: Sleep verb not supported”
In the datasheet I found that the pin 240 can control the system to sleep and wake up, but I don’t know which pin on the pin240 corresponds to the board.And I guess pin 240 is the J40 pin1 , so I do some experiment, but it just make the system poweroff and on, not the suspend.
Hope for your helps, Thanks
