I was hoping for some pointers on this issue I am having while trying to enable eth0 interface on my Pine64 SBC.

 

I am running the following Armbian version:
 

Title: Armbian 5.38.180128 Pine64 Debian stretch next

Kernel: Linux 4.14.15

Build date: 28.01.2018

I am able to connect a USB 2.0 to Ethernet adapter without any issues. The problem arises when I try to enable eth0 which is the Native Ethernet port.
 

pine64:/# ifconfig eth0 up

SIOCSIFFLAGS: No such device

dmesg | grep eth0 gives me the following:

xxxxxx.ethernet eth0: Could not attach to PHY

var/log/messages shows the following:
 

device (eth0): driver '(null)' does not support carrier detection

device (eth0): driver 'unknown' does not support carrier detection

It definitely looks like a driver issue but reinstalling the following did not help:

firmware-linux-nonfree

firmware-linux

Setting network manager to ignore the carrier and restarting network services yielded no results:
 

$ cat /etc/NetworkManager/NetworkManager.conf

[main]

plugins=ifupdown,keyfile

ignore_carrier=eth0

 

thoughts?

thanks!

Ethernet is currently broken on (some) A64 boards with mainline kernel due to recent changes in the driver. Banana M64, which is a similar design, was happy with such patch https://github.com/armbian/build/commit/6ab13a0122ee80c0ffbd57c0a42a969935787117 while I actually don't have Pine64 (ordered) to check if the same trick works.

Hi @Igor
I was wondering if you were able to figure out Pine64 GMAC issue with 4.14. 

thanks!

Nope, AFAIK it works (don't have any Pine64 except Pinebook) on 100Mbit only like with Orangepi Win, Lime A64, ...
