Hello @xMark94,
The configuration looks good to us. Could you please send us the full dmesg log?
You could also use phytool to access the phy registers directly to see if they have the correct values. You can check it as follows:
phytool read eth1/1/0x1e
Here the register value should be 1.
I can send you the phytool cross-compiled for arm64 so you don’t have to compile it again.
