Hi Team, 

The system structure is using STM32F4 MCU + DP83825I, MDIO communication is norma,Why does the indicator light on the router not turn on and the linkstatus in the dp83825 register is 0 when connected to the router through RJ45?

  • Hi,

    It looks like the link is not getting established. Can you share the status of 0x00, 0x04, 0x10, 0x19? Can you also check that the router can successfully link up when connected to another 100Mbps device?

    -Regards
