主题中讨论的其他器件：DP83869

您好

我们将 DP83869与 T2080在1000Mbps 模式下使用、

在尝试在 uboot 中执行 ping 操作时、出现以下错误：

使用 FM1@DTSEC3器件

已超过 ARP 重试计数；重新开始
Ping 失败；主机169.254.169.108不活动

mii - MII utility commands

Usage:
mii device                            - list available devices
mii device <devname>                  - set current device
mii info   <addr>                     - display MII PHY info
mii read   <addr> <reg>               - read  MII PHY <addr> register <reg>
mii write  <addr> <reg> <data>        - write MII PHY <addr> register <reg>
mii modify <addr> <reg> <data> <mask> - modify MII PHY <addr> register <reg>
                                        updating bits identified in <mask>
mii dump   <addr> <reg>               - pretty-print <addr> <reg> (0-5 only)
Addr and/or reg may be ranges, e.g. 2-7.
