am335x Ethernet issue

paa nooos

Hello

We are having a custom am335x board, based on BBB, and we are facing an issue with the Ethernet controller.
When we are plugging in the ethernet cable, the leds on the connector seems to have some activity (blinking) but
nothing else.

The ethernet transceivers we are using is a Microchip LAN8710A-EZC-TR

eth0    Link encap:Ethernet  HWaddr 84:eb:18:94:30:86 
          inet6 addr: fe80::86eb:18ff:fe94:3086/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:5 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:398 (398.0 B)
          Interrupt:56

Do you have any hint, or any tool that i can use to debug this issue?

Thank you in advance

Hello Biser

ubuntu@arm:~$ uname -r
3.8.13-bone32

ubuntu@arm:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.3 LTS
Release:        14.04
Codename:       trusty

I also take a look at the boot up log

[    1.154811] tilcdc 4830e000.fb: failed to initialize mode setting
Scanning for Btrfs filesystems

[    9.720768] net eth0: phy 4a101000.mdio:01 not found on slave 1

btw using exact the same image on a standar BBB, everything is fine
