i.MX6UL ENET1 (with LAN8720A PHY) not working in Uboot

[lvmh]

I am debugging the IMX6UL uboot network,but the network is not available.I refer to the https://community.nxp.com/thread/389902,but it still didn't work.
I can test the 50M clock with an oscilloscope.I can read the phy ID using the u-boot MDIO commands .IP addresses and MAC addresses have been set.When I ping, I have the following information:
Using FEC1 device
fec_send
fec_send: status 0xc00 index 0 ret 0
fec_send
fec_send: status 0x2c00 index 1 ret 0
ping_timeout
ping failed; host 192.168.1.1 is not alive

Can someone give me some advice?Thanks a million！

Hello lvmh,

     Our i.MX53 Loco & smd board both support LAN8720A, so you can refer to the configurations in u-boot to add LAN8720A driver to your i.mx6 board.

Have a nice day!
