I have a ethernet module "LAN8720" and I have STM32H743VIT8. But MCU has only "LAN8742" driver. Is it possible to add the "LAN8720" driver to the list of drivers?0693W00000GYGImQAP.png

Put the .c and .h files in any place where you like.

Then add them to your project manually and call from your ethernetif.c.

Let the Cube/CubeIDE think that you use LAN8742.

For your code they are compatible. But there is a bug in CubeMX:
