I'd like to wake up the udoo from the suspend, by sending magic packet from Mikrotik router on an connection to the Udoo. This is something I do for all machines and really worked for years. Does WOL is officially supported on Udoo Bolt? There is no sign of it in the manual or in BIOS. RTC wakeup is obviously not enough. Thank you.
Not investigated into this matter (BIOS support, power supply, etc.) NIC is Realtek RTL8111GS. Here is very general info: Realtek site has this... In addition to the ACPI feature, remote wake-up (including AMD Magic Packet and Microsoft Wake-Up Frame) is supported in both ACPI and APM (Advanced Power Management) environments. To support WOL from a deep power down state (e.g., D3cold, i.e., main power is off and only auxiliary exists), the auxiliary power source must be able to provide the needed power for the RTL8111G/RTL8111GS.
Thanks, but this didn't help. I already made sure about: No bios settings regarding wol No link on router when device sleeps in S3 (this link should be kept powered up) Magic packet sent to device interface does not wake up device (surely I didn't expect that without configuration in bios, but trying took only 5 minutes) Soooo... Question to Udoo.org remains the same: Does Udoo Bolt Gear support WOL? Is there any acpi configuration required? If so, which one? Is there any DSDT table setting responsible for that? How this can be changed?
After I boot into Windows and shutdown it can Wake On Lan, but when power cuts off and back on it will not. I suspect the driver enables something but there is no setting in the BIOS that can be found to enable it permanently.
So indeed it is the Power_State related. "Cold Applying Power" would be S0 state. Does it enter D4cold or D4hot in any form? I don't know. Please see this detailed documentation: https://docs.microsoft.com/en-us/windows-hardware/drivers/kernel/device-sleeping-states
Guessing it moves to D3cold along with stopping the PCI clocks when you press shutdown. I may be wrong though.
WoL works just fine here, Ubuntu 20.04 & UEFI BIOS 1.08. I had to force it enabled with systemd though; https://wiki.archlinux.org/title/Wake-on-LAN#systemd.link
this is very informative and intersting for those who are interested in blogging field. using wake on lan it is possible to wake up your computer using the Unified Remote app. However, this feature is typically not enabled by default.
