Looking for a RZ/T1 R7S910025 sample to control the PHY through the EtherCAT control mdio management interface

Hello, the same HEX file, R7S910025 cannot control phy through EtherCAT control mdio management interface, there is no waveform output, phy working mode cannot be configured normally, R7S910018 is OK, is there any difference between the two models of MPU control, Is there a sample for R7S910025 to control mdio management interface to control phy through EtherCAT?
thanks
