Hi,

I have colibri evaluation board with imx7d.
Ehternet was working fine, but it stopped working from yesterday.
I have another imx7d module, in that its working fine.
I tried to update it with toradex easy installer, but there also it did not detect the Ethernet port.
It would be great if someone could help me debug this.

hi @abhilash

Could you provide the version of the Hardware and Software of your module?

Is it possible that you install a regular Bsp image using SD card and then also reset the uboot environment?
Please check then if the Issue is still present?

Best regards, Jaski

Hi @jaski.tx ,
Thanks for your reply.

Could you provide the version of the Hardware and Software of your module?
root@colibri-imx7-emmc:~# uname -a
Linux colibri-imx7-emmc 4.1.44-2.7.4+gb1555bf #1 SMP Wed Oct 4 21:39:05 UTC 2017 armv7l GNU/Linux
Hardware Version: Colibri iMX7D 1GB V1.1A

Is it possible that you install a regular Bsp image using SD card and then also reset the uboot environment?
I installed colibri-imx7-emmc_lxde-image-tezi_2.7-20180104.tar and i did reset.

Please check then if the Issue is still present?
The issue still present.

But other colibri modules are working with same image.

Thanks for the log. The PHY seems to work.
Do you see the Ethernet Port Led blinking when the module is started?
What is the output of ifconfig?
How is your network setup?

I do not see led blinking.

What is the output of ifconfig?

How is your network setup?

We have a dhcpc server running.

Other colibri imx7d modules are working fine with the dev board with the same image.

HI @abhilash

If other modules are working with same Software then it seems to be a hardware issue. Sorry that you have this experience with the Toradex Hardware. You can ask for a RMA and put this community post as reference.

Thanks and Best regards,
Jaski
