Review of v1.1rc1:

• [x] Disappeared project file which was available in previous revisions.
• [x] Just for information purposes. Compared to DevKit (Nucleo), signal RMII_TX_EN connected to the other pin. That is still ok, cause the new pin in the alternate mode can work as desired.
• [x] Regarding signal USB_VDET. In the DevKit and the previous revision, signal USB_VBUS was connected to the CPU pin. Here it is changed to USB_VDET. Was any reason to do that? The pin is 5V tolerant, so that is not a case?

[gkasprow]

in the previous version the USB_VBUS was not connected.

[gkasprow]

there was an error. THe USB_VBUS was not pesent on the sheet symbol

[gkasprow]

I removed R156. And changed this net name to USB_VBUS

[gkasprow]

I moved TXEN to PG11 to keep compatibility with Nucleo firmware
