Re: STM32 Ethernet Demo
hi
i want to port the ethernet demo to the stm32f207.The stm32f207 use RMII on my board.The mac phyter is dp83848i. The clock of dp83848i was connected with pa8(mco1).The board can work normal use firmware about lwip of ST.It demonstrate the hardware should have no problewm. if i connect my board ...
