T2080RDB-PC Cannot ping

sandratrujillog — Wed, 11 Apr 2018 11:48:16 GMT

I have enabled the 1G RGMII (RTL8211E) ethernet ports (Port FM1@DTSEC3 in U-boot and port fm1-mac3 in linux) on the t2080 reference board, assigned IP address. However, I am unable to ping to the computer from the board attached to the network.

From U-boot if I try this connection (ping 192.168.1.2) I get a response. But since linux I configure the network but I do not get the answer.

In linux I follow the following steps to configure the network:

1) vi / etc / network / interfaces

2) I add the following lines in the interface file:

auto fm1-mac9

iface fm1-mac9 inet static

address 192.168.1.3

net mask 255.255.255.0

3) From the console I execute:

ifup fm1-mac9

4) Then I try ‘ping 192.168.1.2’ but I can’t.

From U-boot if I do 'ping 192.168.1.2', I get the following response:

Using FM1@DTSEC3 device

host 192.168.1.2 is alive

PD: I think that the host network computer is correctly configured because I can ping from another terminal with linux.

Attached is the kernel boot up logs.

On the T2080RDB:

ETH4 - FM1@DTSEC3 - fm1-mac3

Why you are configuring "fm1-mac9"?

I have solved the problem. I configured fm1-mac9 because in the login I read the following and thought that it was renamed.

Starting udev

Thank you very much for your answer. I have another question, Why every time that I start the T2080RDB-PC I have to configure the network (interface)? It is normal? I have the fsl-image-mfgtool installed.
