God Day, everyone!

I have a problem with the Device on allwinner A20 processor and realtek rtl8201 network chip. I was able to run linux. The network works great under Linux. Now I'm trying to configure U-boot to load the kernel via tftp server. I created my own my_defconfig file and compiled u-boot with my_dts file working well in linux kernel. In u-boot-2019.01-rc1-dirty I have the following problem:

This is during U-boot startup:

This is U-boot running:

I can't understand why ping fails. MAC address in ENV is: ethaddr=02:09:04:82:82:d0 MAC address is valid and multicast bit is not set. Help me please!
