ETH Not Working

#1

eth doesn’t work. the led at the ETH interface does not light up. It works on another Pi. Same cables, same software. but number 2 makes no mux.
What can I do

#2

the ETH connection is definitely defect. Aren’t the Rockpi checked? It is not a good thing to sell such things to the customer. now I have to wait a long time until I get replacement :frowning:

Hi ingo,

I understand the sentence “number 2 makes no mux”.

What system do you use? What will ifconfig print?

#4

We checked, including functional tests and stress tests.

#5

ifconfig says eth0 OK,
But network status says not OK. the LEDs do not light up
Rockpi number 1 network OK
Rockpi number 2 network Not OK.
Same cables same system MMC
Sent return

#6

Two ethernet? What model?

And what system do you use?

#7

I have 2 rockpi modell A, one OK the other broken
system: rockpis_debian_buster_minimal_arm64_191219_0406-gpt.img

The new device is now there, unfortunately it also has a defect in the ETH socket.
A question? The manufacturer has a problem with reasonable components.
It cannot be that the new device is also faulty. Loose contact in the ETH socket.
Are you not checking the devices for functionality?
