Hi,teams,
I have some questions that I would like to be answered by teams.
apply to EtherCAT port.PHY strap configuration RMII mode ,speed 100M,Full Duplex and auto negotiation enable.It works with a servo connection，but encounter rx align code errors and rx port mask drop.The count keeps growing.
The following is the status of EtherCAT：

What could have caused this?How can I to solve this problem？
Looking forward to teams responses.
