Hi All,
As refer to the example of Keil STM32 Eval board, the Ethernet PHY chip used in eval board is DP83848. But, i have change it to PHY LAN8700 in my Ethernet Application design. May i know, the only things that i have to change in eth_stm32f2xx.h are Default PHY device address and PHY Identifier? Or there are others settings that i need to change ?
