Hello, @patusaembedded :

TechNexion official BSP doesn't provide Yocto thud 2.6. It looks Yocto thud 2.6 is from Yocto community. TechNexion officaial latest stable Yocto release is Yocto sumo 2.5. https://github.com/TechNexion/tn-imx-yocto-manifest/tree/sumo_4.14.y_GA-stable I believe that ethernet works fine in TechNexion Yocto sumo 2.5. ftp://ftp.technexion.net/demo_software/PICO/IMX7/pico-imx7-emmc/DiskImage/pico-imx7_pico-pi_yocto-2.5-qt5_qca9377_lcd-800x480_20200825.zip

From the screenshot you post in mender, it looks the ethernet PHY is initialized properly. What kind of network manager you use in Yocto thud 2.6 (network manager or connman)? (Usually, Yocto uses connman as default network manager)


To get the list of wired interfaces run
# connmanctl services
For example:
# connmanctl services
*AO Wired                ethernet_0eb31468dcc9_cable
Wired interfaces will be shown as ethernet_<mac_address>_cable. Only interfaces physically connected to the network are displayed.
To create static IP configuration run
# connmanctl config <service> --ipv4 manual <ip address> <netmask> <gateway>
# connmanctl config <service> --nameservers <dns-addr> 

For example:
# connmanctl config ethernet_0eb31468dcc9_cable --ipv4 manual 192.168.1.100 255.255.255.0 192.168.1.254
# connmanctl config ethernet_0eb31468dcc9_cable --nameservers 8.8.8.8 4.4.4.4

BR,

Richard

@richard-hu tks. I stay using systemd-networkd. Lines 264-267 of the my local.conf https://gist.github.com/patusaembedded/ce9dd70a289747d2109f4c654cd009af

I tried several things in the tutorial below, but it didn't work: https://hub.mender.io/t/how-to-configure-networking-using-systemd-in-yocto-project/1097

What I need to change in my local.conf to solve my issue? How to solve my issue ? How to use connman in my 2.6 (thud) Yocto project

Closing. We didn't implement support for Yocto 2.6 (Thud).
