[SOLVED] ODROID-H2+ NETWORK LAN 2.5GBE R8125 driver

[der.einstein]

Dear odroiders,
I installed Ubuntu 20.04 on an NVME SSD in my shiny new ODROID-H2+ just before finding out that neither the onboard 2.5 GBE LAN ports nor the WIFI dongle 5a work out of the box with this board and with this OS.
I tried:
- downloading the driver source from the realtek site on another PC
- downloading the needed packages and dependencies on another PC
- installed packages and dependencies on the H2+
- tried compiling the drivers on the H2+

It failed for both the WIFI as well as the LAN network adapters!

Did someone succeed and is able to tell the "how to"?

Thanks a lot!

Hi.

Have you read this Wiki page? https://wiki.odroid.com/odroid-h2/appli ... _on_h2plus
This page describes "How to install the LAN driver in various ways, with the internet or without that".

I recommend you to install the LAN driver using the DKMS Debian package so that you don't have to re-install the driver every time you install the new kernel.

I believe the .deb or manual installation perform both a DKMS installation with the same result. Someone to pitch in to confirm?

FInally, I succeeded using my smartphone with USB tethering.
The guide on the wiki page above did the trick, however, before you wrote the link I could not find that information in the wiki. So many thanks there!
I have working WIFI and LAN no!!!

Cheers.

Glad to hear that.

There's no difference between those two methods unless the Debian package is installed via the Launchpad PPA.

[dkking]

can you use the dkms method in fedora?

Hi.

You probably can install only the DKMS using the integrated script.

Clone r8125-dkms repository and use that script.

Code: Select all

git clone https://github.com/awesometic/realtek-r8125-dkms
cd realtek-r8125-dkms
sudo ./dkms-install.sh

Please let me know the results.

I'm going to piggyback on this thread

I managed to install the driver, but somehow I still can't establish a network link. I keep getting a "No media detected". Strangely enough, it is possible to trigger the WoL from another client on my LAN. So the media (CAT6 cable) is there and properly connected. I have tried this with several different LAN configurations (H2+ connected to a variety of 1GBit/s switches and H2+ directly connected to one of the 1GBit/s Ports of my internet router (AVM Fritzbox 7590).

I could use a 1GBit/s-USB3-adapter (which I used for driver installation over the internet), but that would take away one USB3 port and leave me with two useless LAN ports onboard.

Anybody have any ideas what else I could try?

You can try using ethtool to force 1G or 100M mode and avoid autonegociation.

it installed, ill reply once again when it works after a kernel upgrade. thanks again

Thanks for the tipp, but it didn't help either.

I even reinstalled Ubuntu 20.04 Server, installed build-essential, net-tools and ethtool (using an USB3-Ethernet-adapter) and redid the driver installation as in

Code: Select all

git clone https://github.com/awesometic/realtek-r8125-dkms
cd realtek-r8125-dkms
sudo ./dkms-install.sh

.

There are two NICs enp2s0 and enp3s0

But the problem remains the same. Whatever parameter I set, ethtool keeps telling me "Link detection: no" although the LEDs on the RJ45 port are flashing.

The H2+ is reacting to Wake-on-LAN, booting Ubuntu 20.04 Server, but it doesn't get an IP address.

[SatDad]

stuck with the same problem yesterday, both nic's did not respond even link led was up and traffic blinking.
Finally i used webmin netconfig to set both to DHCP and it works.
Just wondering both nic's responding to wol within a second but need about 30 sec to be reachable via network.
Assume there ist still something wrong, but at least i'm able to connect in the meantime

[mad_ady]

If you're connecting to a managed switch with stp, the ports are are in learning state for 30s to prevent loops. They are up, but just receiving traffic. See if you can run tcpdump on them and see traffic.

[pfgsnoopy]

By now I'm almost certain that I either made a boneheaded rookie mistake or the H2+ is defective.

If you're connecting to a managed switch with stp, the ports are are in learning state for 30s to prevent loops. They are up, but just receiving traffic. See if you can run tcpdump on them and see traffic.

In my case all switches are unmanaged. I have ordered a managed PoE-switch (Zyxel GS1200-5HPv2 for a Raspberry Pi cluster project), but that won't be here for a couple of days.

What puzzles me is that the H2+ responds to WoL and the LEDs on the RJ45 port are blinking, but still ethtool shows that there is no link.

[mad_ady]

To rule out the switch, connect a straight cable between both h2+ ports and see if they come up.

[SatDad]

same to me, try to set them to dhcp at networkconfig and they will show up after 30 sec

[pfgsnoopy]

To rule out the switch, connect a straight cable between both h2+ ports and see if they come up.

Since I tried it on 2 different switches and directly on one of the ethernet ports of my router, I doubt that it's a switch problem.

Are the LAN ports on the H2+ able to establish x-linked connections, 'cause if they aren't connecting both ports with a standard LAN cable won't get you anywhere.

But I tried it anyway and as I expected, both onboard NICs stay down.

edit:
Upon reading this post, one could argue that I was impolite. That was not my intention. So please let me apologize. I'm pretty frustrated right now, but that's no excuse for bad behavior.
Thanks for trying to help me.

There isn't even a link at the enp2s0 and enp3s0 entries (in Webmin). The enx000ec6bf1bea entry is linked to a page where I could disable/enable DHCP and do all the other TCP/IP configuration changes.

[mad_ady]

Hmm, not sure what to suggest next. The ports should have autosense, so a straight cable between them should work. Let's see what odroid suggests next.

Thank you anyway.

Let's see what odroid suggests next.

I hope they can come up with a solution. Otherwise I'm afraid, I'll need to get a replacement unit.

[mad_ady]

I expect odroid will reply on monday. In the mwantime, if you have time can you boot windows and see if it behaves the same way? To rule out kernel/driver issue.

[SatDad]

I'm not quite sure, fiddled around that much, but I think I created both nics again via "add new interface" even with the same names. At least I get that thing up and running. Maybe it is worth a try
Ps: I just checked another H2b, same behavior, as long as there is no cable connected, you cannot change anything on this port. And I don't think it's a hardware problem, I had the same strange behaviour only showing a sync with 10 or 100 mbps before and at least it is trying to sync

Unfortunately, Windows is not an option. The only Windows license I have is runnig on my Surface Pro.

Unfortunately, Windows is not an option. The only Windows license I have is runnig on my Surface Pro.

Windows license allows you to download windows 10 and install it on a machine for 30 days without activating it. In fact, it will not stop working after 30 days, you’ll just get nags and a couple of meaningless features wont work (e.g., you can’t change the wallpaper from a black screen). They allow this for exactly your use case - testing and validation.

When the install gets to the page asking for an activation key just click the “skip” button on the bottom corner of the screen.

Unbelievable! You are right! Using Webmin to re-add the two onboard interfaces did the trick! I don't know why, but it did it!

Thanks!

Thanks to everybody who took the time to work with me on that issue!
