Conversation
I assume if I got board with this revision, this workaround will work for me (for any board from this line) ? |

On STM32 F767 rev A devices ,Ethernet peripheral had problems on RMII interface, on MII this was not the case. This commits implements a tentative workaround for the issue rerfered to as Ethernet erroneous data received in RMII configuration in the Errata sheet below: http://www.st.com/content/ccc/resource/technical/document/errata_sheet/group0/23/a6/11/0b/30/24/46/a5/DM00257543/files/DM00257543.pdf/jcr:content/translations/en.DM00257543.pdf Note that the issue has been fixed in 'Z' revision. of STM32 F767 MCUs.
Yes, the case where reset is needed will never be hit with rev Z. |

As indicated in the Errata sheet, the RMII issue concerns all STM32F76xxx and TM32F77xxx,
So maybe we should increase this define test ?
