issue : eth0 can not ping DUT. Please help !!

[jason9tsai]

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 :

Hi jason

had you used linux driver for that chip:

net: phy: realtek: add rtl8201f driver - Patchwork 

first please try in uboot, seems processor used in that case is i.MX6UL, try nxp uboot:

http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/tree/?h=imx_v2016.03_4.1.15_2.0.0_ga

also one can try loopback test.

Best regards
igor

Hello Igor,

   I have modify device-tree, it can work.

   Thanks for you help !!

&fec1 {
   pinctrl-names = "default";
   pinctrl-0 = <&pinctrl_enet1>;

   status = "okay";

};

   fsl,pins = <
