Hello,

I'm using a wandboard (rev d1) and building the fslc-image-network-full-cmdline image (honister branch). I've got ethernet wired to a switch on my home network, but I cannot figure out how to setup this build to bring up eth0 via DHCP. Any help would be appreciated. Is this image supposed to bring up eth0 right out of the box?

I have this issue after updating meta layers to honister and kernel to version 5.10. My problem was fixed by changing fec node in device tree - phy-mode value should be rgmii-id and phy-reset-duration should be increased:

phy-mode = "rgmii-id";
phy-reset-duration = <10>;

You can see at commit logs in imx devicetrees on kernel repository for more information.

Best regards,

There is a recent fix in 5.15.13 for Ethernet on wandboard
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/arch/arm/boot/dts/imx6qdl-wandboard.dtsi?h=v5.15.13&id=ef73e3b650b7b1ad4080b8e7aeba5e36e19f0932

After applying this fix, I can confirm Ethernet is functional.

To get an IP address via DHCP:
udhcpc -i eth0

There is a PR in meta-freescale layer against [master] branch, which
upgrades the Kernel to 5.15.13:
https://github.com/Freescale/meta-freescale/pull/936

Once merged, you can build the image of [master] to verify if your
problem persists.

After applying this fix, I can confirm Ethernet is functional.

udhcpc -i eth0
