Recently i bought 4 rock pi’s out of 4 one of the rock pi ethernet is not working , led is blinking but no eth0 in interface list or dmesg , tried changing cables/ports , nothing . im using same armbian ubuntu bionic on all 4 , 3 are working perfect, maybe hardware issue?
Have you tried using the exact same SD that is used in a RockPi 4 with working ethernet?
Yes, ethernet is working on other rock Pi with same emmc
I have exactly the same behavior.
Any suggestions what to do or how to solve this?
Nope , its hardware issue , you have to return
Thanks for your fast reply! I will return the defective one.
Have you tried
It can’t connect via remote or ssh. So no chance to try it. When using an Image on SD Card the Ethernet Port works. But when I boot from EMMC, it doesn’t do anything… Even pinging is not possible.
Do you have serial console or HDMI?
I already sent the faulty ones back to be replaced…
If I ever have another one with this behavior I will keep it and do some tests.
