TDA4VM: uses rgmii mode communicate fail in mcu_cpsw

Part Number: TDA4VM

Hi,

In our board,the phy chip we use marvell 88e1512。

The phy can be recognized in u-boot, and the phy register can be read and written normally using mii,

but it will fail to obtain the ip automatically using dhcp,

and the ping of the host PC will also fail after manually setting the static IP.

Please how to solve this problem?

Best Regards,

jie
