Wake on Lan is working with core 160?

[hjkl (H&M)]

Thank you very much @bonnietwin and @bbitsch

@bonnietwin

From Core Update 158 to 162 the Linux kernel is changed from 4.14.232 to 5.15.6 and in that range the wake on lan setting stopped being persistent. If you turn off the APU with the setting at d then it will not respond to any magic packets. You will need to create a script to set the wake on lan to g when the APU is booted up.

I have set ALL network cards in APU1 to wol=g and powered down the box:

On APU1 I did executed these commands:

ethtool -s green0p0 wol g
ethtool -s green0p1 wol g
ethtool -s green0p2 wol g

APU2 card connected to APU1 now goes in forwarding state after APU1 halts/power off:

Jan 13 22:10:05 silver-x86-64 kernel: igb 0000:02:00.0 green0p1: igb: green0p1 NIC Link is Down
Jan 13 22:10:05 silver-x86-64 kernel: green0: port 2(green0p1) entered disabled state
Jan 13 22:10:06 silver-x86-64 kernel: igb 0000:02:00.0 green0p1: igb: green0p1 NIC Link is Up 10 Mbps Full Duplex, Flow Control: RX/TX
Jan 13 22:10:06 silver-x86-64 kernel: green0: port 2(green0p1) entered blocking state
Jan 13 22:10:06 silver-x86-64 kernel: green0: port 2(green0p1) entered forwarding state

And, as expected, the WOL command from APU2 to APU1 now works: my script that powers it on and check that samba is up reported success:

./RedFire up
is_alive: ping a.b.c.d attempt 6. smbclient:Seems samba on a.b.c.d is up

@bbitsch

The test descriptions for the coreboot firmware of APUs [PC Engines] Regression test results - Google Tabellen state problems with WOL since v4.14.0.4

@bonnietwin

So only solution is to install v4.14.0.3 which is the last version without any wol issues flagged.

Thank you - I will try to go back to 4.14.03, BUT the APU1 needs flashrom 0.9 to accomplish that.
And, up to now, I failed to find a binary - I know I had a TinyCore bootable USB somewhere, but I did not found it yet.

The flashrom 1.2 that is shipped now in core 162 does not work - see this post on errors thrown on APU1. How update the BIOS from IPFire with PC Engines APUx - #15 by hjkl

So until I found the flashrom 0.9 I will have to run a cron job to set wol=g on all cards from APU1

Thank you again!

Late edit: found my TinyCore USB Boot and that had on it FLashROM v0.9.7-r1711-APU: I have downgraded APU1 bios to v4.12.0.6. that was on the USB disk with TinyCore.

Board : PC Engines apu1
HW Version : 1.0
Serial : -64
BIOS Version: v4.12.0.6 (10/29/2020)

Later edit: neither BIOS Version: v4.12.0.6 (10/29/2020) or BIOS Version: v4.14.0.3 (08/10/2021) put Wake-on: g

Board : PC Engines apu1
HW Version : 1.0
Serial : 1012235
BIOS Version: v4.14.0.3 (08/10/2021)

I tested both - all 3 network cards go with Wake-on: d after reboot.

So I have added in /etc/sysconfig/rc.local these lines.

ethtool -s green0p0 wol g
ethtool -s green0p1 wol g
ethtool -s green0p2 wol g

It seems that new kernel does that and not the BIOS firmware…
But I am not an expert…

Thank you very much!
