STM32F76 RMII Errata: Any hack/workaround

Despite several promises to keep us informed about the findings around the error with RMII in F76, only ''ask your FAE'' was posted here. Now silently Rev. 3 of the F76 errata appeared, stating ''No workaround''.

Does anybody have a hack to work somehow reliable with RMII on F76, as on the Nucleo-F769?

Thanks

B.t.w.: It is no more possible to reply to the threads around ETH on F76 that were posted not even a month ago. Trying to reply, ''404'' is received as answer. It is not good, if people bring up really old threads, but not even a month is a time span to short i.m.h.o.

I've just [DEAD LINK /public/STe2ecommunities/mcu/Lists/STM32Discovery/Flat.aspx?RootFolder=/public/STe2ecommunities/mcu/Lists/STM32Discovery/Stm32F767%20Nucleo%20Ethernet%20does%20not%20always%20start&FolderCTID=0x01200200770978C69A1141439FE559EB459D75800084C20D8867EAD444A5987D47BE638E0F&currentviews=94]succeeded to do so. The 404 might've been one of the many of this forum software's quirks.

Hi,

The limitation ''Ethernet erroneous data received in RMII configuration'' is fixed in Revision Z of the STM32F76xxx and STM32F77xxx (see
