Dear Toradex Support,
The ethtool is a command-line tool in Linux for managing network interface devices.
I am trying to use LAN7850 and in this step, I need to use the ethool command to setup EEPROM of the LAN module, Could you please let me know how I can install the package ethtool command in the imx8 mini SoM? Is it doable?
Thank you so much for any help.
Best regards,
Mehrdad

Greetings @Mehrdad,
You are correct ethtool
is not shipped with TorizonCore by default. As of this moment your options are too either re-build TorizonCore to add the ethtool
utility. Or, you could install ethtool
inside a container.
I did a quick test with a Debian based container that has --privileged
and --network=host
. With this it appears that ethtool
can view the Ethernet devices on the host:
ethtool ethernet0
Settings for ethernet0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Supported pause frame use: Symmetric
Supports auto-negotiation: Yes
Supported FEC modes: Not reported
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Advertised pause frame use: Symmetric
Advertised auto-negotiation: Yes
Advertised FEC modes: Not reported
Link partner advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Half 1000baseT/Full
Link partner advertised pause frame use: Symmetric Receive-only
Link partner advertised auto-negotiation: Yes
Link partner advertised FEC modes: Not reported
Speed: 1000Mb/s
Duplex: Full
Auto-negotiation: on
master-slave cfg: preferred slave
master-slave status: slave
Port: Twisted Pair
PHYAD: 7
Transceiver: external
MDI-X: Unknown
Supports Wake-on: g
Wake-on: d
Link detected: yes
Though I’m not sure if this would be good enough, to configure your LAN device. It’s also obviously not as convienent as having ethtool
out of the box on the host OS. Let me bring up the idea of adding ethtool
to TorizonCore to our team here. Though for the time being you’ll need to work around this limitation.

Dear @jeremias.tx ,
Thank you for your response using ethtool on TorizonCore. I appreciate your help on this matter.
I would like to follow up on your suggestion to install ethtool inside a container with the --privileged and --network=host options. However, I am not sure how to set up this container properly. Could you please provide me with instructions or resources on how to create a container with the necessary options to use ethtool on TorizonCore?
Thank you for your time and assistance.
Best regards,
Mehrdad
It’s not too complicated, you just have to run a container like so:
docker run -it --privileged --net=host <whatever Debian based container image you want to use> bash
This should give you a terminal inside this Debian based container. From there you just treat it like normal Debian:
# Inside the container
$ apt update
$ apt install ethtool
Then that’s it you should have ethtool
installed in this container and should be able to use it inside this container. Due to --net=host
and --privileged
, you should be able to access the host ethernet interface from inside the container.
Best Regards,
Jeremias
