DP83620: Link status状态一直为0,无法ping通!

Part Number: DP83620

配置Auto-Negotiation,PHYSTS寄存器状态DUPLEX STATUS不停变化,是不是一直在匹配?

  • 您好,

    看下面手册截图,DUPLEX STATUS位只有在启用并完成自动协商且存在有效链接时,或者如果禁用了自动协商且存在有效链接时,此位才有效(Note: This bit is only valid if Auto-Negotiation is enabled and complete and there is a valid link or if Auto-Negotiation is disabled and there is a valid link.)
