Cannot make ethernet to work

[bfgelectronics]

Ive got my Radxa CM3 and i flashed on a sd card the debian and ubuntu servers images for the E23 board.
When i power up the E23 carrier board with the CM3 attached , the led from the CM3 starts blinking up , but when i connect the ethernet cable on one of the ethernet ports, the amber let lights up and blinks, but it isnt detected by my router. If i insert the same cable on the other ethernet port , the green led lights up and same beheaviour.
I tryed connecting directly a ethernet port to my laptop and it seems that it the laptop tryes to connect , but after a few seconds, it disconects and the process repeats.

TLDR: I tryed using the images for the e23 boards and ethernet is not working

The fact your laptop tries to connect but it fails might either mean misconfiguration (or lack of sane configuration), or something wrong with a cable.
I'd assume the drivers are fine, and since it's not a prototype carrier board anymore (I think?), I'd rule out design errors.

Thanks for the answer @tomek-szczesny the cable is fine. Also since the e23 board has no video out, i couldnt make any configuration, i just downloaded the 2 mentioned images, burned them to a sd card, and tryed them.

I can't help you any more than that, I'm still waiting for my unit, and the carrier board I'm designing isn't ready yet :)

Perhaps it'd be better idea to ask for directions on Radxa forum instead.

Good luck with your project! :)
