Sometimes at startup of a BeagleBone Black there is a wrong mdio address for ethernet phy

4a101000.mdio:02 instead of 4a101000.mdio:00

dmesg return this message

net eth0: initializing cpsw version 1.12 (0)

libphy: PHY 4a101000.mdio:00 not found
net eth0: phy 4a101000.mdio:00 not found on slave 0

libphy: PHY 4a101000.mdio:01 not found
net eth0: phy 4a101000.mdio:01 not found on slave 1

There is a way to test also at startup 4a101000.mdio:02 ?

This was fixed awhile ago, either run:

cd /opt/scripts/tools/
git pull
sudo ./update_kernel.sh

or tell us what kernel your running:

uname -r
