Hey guys,
I am trying to wake up a RIoTboard over Ethernet.
The hardware setup is the following:
RIoTboard (Ubuntu) -> Ethernet -> RIoTboard (Yocto)
The Yocto board is "asleep" and I want to wake it up from the Ubuntu board.
What I do now is to put the board in the so called DORMANT mode:
echo mem > /sys/power/state
------------------------------------- Out of topic, but useful -----------------------------------------------------------
If I initially enable UART wake up, I can wake it up just by typing a character on the serial console.
echo enabled > /sys/bus/platform/drivers/imx-uart/21e8000.serial/tty/ttymxc1/power/wakeup
Also using RTC seems to be pretty straight forward:
/unit_tests/rtcwakeup.out –m mem –s 10
This command indicates to sleep for 10 secs. This command automatically sets the power state to mem mode.
----------------------------------------------------------------------------------------------------------------------------------
However, I want to wake up the board over Ethernet. Found that it is usually done, by using WOL (Wake on LAN). The board supports UART, USB and RTC (Real-Time Clock), but nowhere is mentioned to support WOL:
The following topic provides patches for i.MX6DQ and a Sabre board, I do not find a possibility to use them with the RIoTboard:
Wake on lan in mx6 sabresd board
Do you know a way to accomplish WOL using the RIoTboard?
Let me know if something is not clear.
Thanks in advance!
Cheers,

Hey guys,
Got no reply, since quite some time, but for the ones that might take a look at this:
I have found that the Ehternet Transceiver of the RIoTboard actually supports Wake On LAN:
You can find it on page 18 in the Datasheet of the chip AR8035:
I don't know if this helps at all, but still is "some" progress.
Thanks in advance!
Cheers,
