I try to ping DUT in the same domain, but it can not work.

SoC I.MX6 

Module RTL8201F 

 

  • I have check eth0, and modify IP addr.

$/etc/init.d/networking stop

$ifconfig eth0 hw ether 82:1d:e5:23:53:15

$/etc/init.d/networking start

$ifconfig eth0 192.168.1.4 up

$ ifconfig

  • I have used ethtool to check. And I  remove Network Cable , the log has show link is not ready .
  • I have check dmesg. It looks okay.

Log is show :
