Ethernet not working on Colibri iMX6ULL

Hello,

Recently when I flashed a new Toradex Reference Multimedia Image, the ethernet port on my SoM stopped working and wasn’t able to get it starting again.

Leds of ethernet port are not blinking, tried switching cable, went to see if PHY driver was working (it was). But nothing seems to solve the issue.

Hi @rjjong1 ,

Thanks for using the community.

What’s the output of “ifconfig” when entered in the command line?

Best Regards

Hi @kevin.tx ,

This is my output:

Also I noticed the ethernet chip was getting hot. So I think it is something hardware related.

I realize this is an old thread, but i wonder if there was ever a resolution. I have a Colibri iMX6ULL board in a Colibri Evaluation Board with Colibri-iMX6ULL_Reference-Minimal-Image-Tezi_5.7.6+build.29 installed.
I get no lights on the Ethernet port and ‘ip link’ reports eth0 as DOWN. Running ‘ip link set eth0 up’ seems to have no effect.
dmesg does not seem to report any error:
[ 19.897702] Generic PHY 20b4000.ethernet-1:02: attached PHY driver [Generic PHY] (mii_bus:phy_addr=20b4000.ethernet-1:02, irq=POLL)

Hi @brianhackel ,

Your issue appears to be hardware-related. Do you have another Colibri-iMX6ULL module available for testing?

In the future, please avoid hijacking existing threads. If your issue is similar to an existing one, we recommend creating a new thread and including a link to the relevant discussion.
