[Solved] Seagate Personal Cloud NAS SRPD20 WOL

[tony_p]

Hi folks,

I have a Seagate NAS running Debian Bookworm. I'm unable to get it to sleep, or resume from sleep via a WOL packet like it does with the original firmware.

I searched though the original firmware and found the required code.

It doesn't actually sleep, it shuts down and can be woken by WOL.

I figured out the box needs 2 things to accomplish this - the ethtool eth0 wol needs to be set to "g", and 2 GPIOs need to be set.

Debian 12 (and perhaps earlier versions) already automatically sets eth0 WOL to g, but for the sake of completeness, this can be manually set with

Code: Select all

ethtool -s eth0 wol g

The GPIO code for enabling WOL in the ethernet chip on the Seagate is

Code: Select all

echo 59 > /sys/class/gpio/export
echo 61 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio59/direction
echo out > /sys/class/gpio/gpio61/direction
echo 1 > /sys/class/gpio/gpio59/value
echo 1 > /sys/class/gpio/gpio61/value
echo 59 > /sys/class/gpio/unexport
echo 61 > /sys/class/gpio/unexport

Issue poweroff, and the NAS can be woken via WOL magic packet.

Hello tony_p, welcome to the forum!

Thank you for sharing your solution.

Where/how did you find this GPIO code sequence?

NOT FOR DEBIAN!

This code is from the stock firmware on the Seagate Personal Cloud NAS, SRPD20, and possibly others in the family. It is here for informative purposes on the GPIO code required to enable WOL in these devices running Debian.

Code: Select all

#!/bin/sh

set -e

GPIO_SYSPATH=/sys/class/gpio
GPIO_PM=false
DART=false

	printf "$@\n" >&2
	exit 1
}

	echo out > $GPIO_SYSPATH/gpio61/direction
	echo 0 > $GPIO_SYSPATH/gpio59/value
	echo 0 > $GPIO_SYSPATH/gpio61/value

	echo "$val" > $GPIO_SYSPATH/gpio59/value
	echo 1 > $GPIO_SYSPATH/gpio61/value

Hello tony_p, welcome to the forum

Thank you for having me. I won't be able to contribute much as I only run Debian on a Seagate NAS, but every small piece helps.

Where/how did you find this GPIO code sequence?

I'm guessing that you would prefer the short version, as opposed to the long version where I list every file I looked at and every test I ran?
I found the information in the stock firmware in a script called /sbin/pm-config-hw.
It has been shared here - viewtopic.php?p=794765#p794765

Totally agree, every small piece helps. Thanks again for your contribution.

You did a great job. I moved your post with the script you found here as it is a better place for it.
