Dear NXP experts.

I developing the custom board based on ls1028ardb board

and attached vsc8504 phy to ls1028a cpu.

the vsc8504 phy uboot driver is added on uboot/drivers/net/phy/vitesse.c

<figure1> is block diagram, how to connect vsc8504 to cpu

and ping test on uboot,

<figure2> is test configuration

Runnnig Wireshark on PC Side.

the custom board arp request packet is captured by wireshark

and pc send reply packet, but custom board can't receive the reply

but sometimes can receive about once in a hundred

Please refer and feedback.

what i should do?
