Hello,
We are using ksz8863rll ethernet switch with AM3358 Processor in our custom board. It is connected with CPU in rmii mode. We have used MDIO bus for communication between ksz8863rll and am3358 for configuration. We are able to detect eth0 and got the ip but phy is not detected. We are getting below error:
Below is the dts file of our board:
