T2080QDS : Network issue

abhijit_thorat — Tue, 14 Jul 2020 12:25:10 GMT

Hi,

I am using T2080QDS for development project. I want to transfer data to another machine.

I build deployment images using Yocto and deployed images using tftp server.

In boot mode I am able to ping 8.8.8.8

But in kernel mode no interface is up automatically. Also I checked file /etc/network/interfaces

There is no interface in that file.

What are the steps to make network working? Do I need to configure interface manually?

Is there any documentation for that?

I refer document QorIQ SDK 2.0 Documentation but not find anything.

Following are the environment variables. Boot logs are also attached.

Hello Abhijit Thorat,

You need to configure the Ethernet interfaces manually.

For example:

root@t2080qds:~# ifconfig fm1-mac3 8.8.8.8
root@t2080qds:~# ifconfig

Please refer to the following

FM1@DTSEC3(MAC3)

FM1@DTSEC4(MAC4)
FM1@TGEC1(MAC9)
FM1@TGEC2(MAC10)
FM1@TGEC3(MAC1)
FM1@TGEC4(MAC2)

Thanks,

Yiping

Is there any way to do this automatically. So that when board boots, interface will be UP directly and no need to configure interface manually?

Thanks,

Hello Abhijit,

You could modify /etc/network/interfaces and make this file into the rootfs filesystem.

In Yocto build environment

1. $ bitbake init-ifupdown -c cleansstate

2. Please modify sources/meta-freescale/recipes-core/init-ifupdown/init-ifupdown/qoriq/interfaces to add the Ethernet interface information as the following.

auto fm1-mac3
iface fm1-mac3 inet dhcp

3. Rebuild rootfs filesystem

$ bitbake fsl-image-core

You could refer to https://community.nxp.com/message/1006471?commentID=1006471#comment-1006471 .

Thanks,

Yiping
