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


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:


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.
