DM8107 network problem

You need to ensure gigabit mode and auto negotiation is enabled in the phy . The cpsw driver just reads the status from phy driver and doesn't need any change. Also you need to ensure that you connect to a gigabit network / to a peer with gigabit phy so that auto negotiation between phys settles phy speed of your custom board to 1000M.

Hi Yogesh

     Thanks for your reply!

     I will be sure gigabit mode and auto negotiation. But I have a question

     Whether should we config the sata pll and pcie pll .

     Thanks

Hi Yogesh

     Now It have a strange problem

     My DM8107 custom board can work with 100M which connected to a 100M network switch

     But when connected to a 1000M network switch, the network can not work

      Whether have you encountered

      Thanks 

I have a 8107 EVM and I'm able to connect to gigabit network and transfer data without any issue. The EVM has Atheros AR8031 phy. This surely points to phy configuration problem on your board.

Hi Yogesh.

    Could you give me your driver/net/cpsw.c.

     and I can refer to it .

     thank you
