Part Number:AM5729
我们公司使用的 am5729,公司自己制作的板子,使用 phy DP83867IRRGZ ,用网线直连同样的am5729板,无法Ping通,但是板子用网线连上交换机,能ping通
问题:1. 是什么原因导致网线直连两台设备无法ping通呢
2. 有什么解决方法吗
Nancy Wang:
请贴出您使用的SDK,并且详细描述一下两块板子直连是如何ping的。
,
Chandler Liu:
SDK版本为 5.03,系统为 premmpt rt linux,两块板子的ip为同一网段,在板子进入Linux系统后,使用ping命令
,
Nancy Wang:
请贴出以下指令的结果以及ping命令的信息,我需要咨询相关工程师再给您回复。
ethtool eth0/eth1
ethtool -S eth0/eth1

板子网口为千兆网口,直连一台百兆网口的设备ping不通,直连另一个千兆网口是能ping通的
