I cannot find the ETH connectivity option in the Pinout & Configuration window. It is listed as an option in the datasheet, and pins are given for the various MII options.
What can I do to configure the MCU with a RMII interface to an external PHY chip?

The WLCSP180 package (STM32F779AIY) doesn't break out an ETH_MII_RXD0/ETH_RMII_RX, so ETH isn't possible.

It's there on more recent versions of STM32CubeMX. v6.8.1 is quite old.

Hello. This did not solve my problem. I installed the latest CubeIDE and CubeMX but my specific MCU does not have eth connectivity there in either instance. STM32F779AIY. Am I interpreting the datasheet incorrectly, and this chip does not in fact have ethernet (RMII or MII) connectivity?
