i just got access to an Nucelo F767zi board (STM32 MCU) with an on-board Ethernet Controller attached via RMII.
Since i found no existing netdev driver for this hardware configuration nor any related pull requests I plan to do an implementation by myself.
I just wanted to ask if anybody already has experiences with the on-board ethernet and may got some useful tips or information?
Thanks in advance & Regards
Thanks for your interest into RIOT and STM32 boards.
There is an (old) existing PR  that tries to add an Ethernet driver for stm32f4. Maybe it's not very different for F7 and you could use it as a starting point ?
Thanks Alex! It turns out that the PR could be adopted to use the F7 family. I try to add my "fixes" to the PR.
