Tool/software: Linux
Hi all,
I'm configuring for a custom board base on AM335x EVM, my custom board use KSZ9021 for Ethernet, but when board booting, the Ethernet dont work,
The log show below:

When the booting process finish, the Ethernet cannot detect IP address, but when i try command: /etc/init.d/networking restart, in the firsrt time cosole show:
Reconfiguring network interfaces... ifdown: interface lo not configured
ifdown: interface eth0 not configured
ifconfig: SIOCGIFFLAGS: No such device
done.
In the second time, the console show:

and Ethernet can detect IP Address, can anybody help me fix this issue
This is my device tree config:
