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
