Network connection problem with T2080RDB-PC

I am trying to set up a T2080RDB-PC. I can connect via console to access uboot/Linux. I have connected

the ETH2 port (as labelled on front of system) but cannot seen to get a network connection working from

either u-boot or Linux. Have verified that am trying to use the right port as the MAC address is printed on

the board socket, and have checked that this is what I am attempting to use from u-boot/Linux.

 

In u-boot have set environment so that FM1@TGEC3 is the default ethernet device, as sen from this u-boot

startup snippet:

 

Net: Fman1: Uploading microcode version 106.4.18
FM1@DTSEC3, FM1@DTSEC4, FM1@TGEC1, FM1@TGEC2, FM1@TGEC3 [PRIME], FM1@TGEC4

 

According to the user guide FM1@TGEC3 actually maps to the ETH2 labelled port, further confirmed with

the uboot bdinfo command that shows I am using the correct device:

 

ethaddr = 00:04:9F:05:34:46

 

When trying to ping from uboot, I get:

 

ping 10.1.0.22
FM1@TGEC3 Waiting for PHY auto negotiation to complete................................ TIMEOUT !
FM1@TGEC3: No link.

 

The ETH2 Tx/Rx lights on the panel are in a continuous alternating flash pattern.

 

Anyone any idea what is wrong?

 

Cheers Steve.
