STM32F407VG + LAN8720 ETH BOARD (Waveshare)

Hello!

I am trying to run an Ethernet on STM32F4DISCOVERY board (with 407VG MCU) using a ETH BOARD module from Waveshare.

In the CubeMX, I added ETH with RMII, in the settings I entered the MAC and set the PHY Address to 1 (found in the datasheet for this module).

After that I adeed LWIP, turned off DHCP and set the mask and gateway of the router and entered a free IP, turned on UDP.

Next I generated a code for SystemWorkbench, added a gnetif structure to variables, and put functions (ethernetif_input and sys_check_timeouts) in a while(1).

Then I tried ping a board, but it doesn't work. Also in router settings I can't find any new device with specified MAC.

Already desperate, I still can not understand what the problem is ...

There are screenshots with my settings.
