NOTE: The STM32H7-BSB Rev 1A/2A baseboards doesn't have the RJ-45 connector so the Waveshare LAN8720 ETH board should be connected to the P2 header with a special cable. The pin-out is as follows:

Here are some troubleshooting tips, in case tftpboot does not work for you from U-Boot:
As trivial as it sounds make sure that the board is connected to the LAN with an Ethernet cable.
Suppose you are still not getting your file from the TFTP server. It is possible that the problem is on the host side - you must set up a TFTP server correctly. Just google for "how to set up a tftp server" and follow the advice from some top articles.
Make sure you have copied a file you are trying to download to the TFTP server directory on the host.
Disable the firewall on the host since get enabled, it will block TFTP requests from the target.
On the target, make sure that you have set
ipaddrandserveripcorrectly. Checkethaddrand make sure that you don't have another embedded board (eg. another STM32H7 SOM) configured for the same MAC address.
