Network connection problem with T2080RDB-PC

steveosselton — Thu, 04 Jan 2018 18:56:12 GMT

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.

There is a typo in the QorIQ T2080 Reference Design Board Quick Start, Table 2.

Corrected version is:

Think is also general typo in that docs have "FM1@GTECn" whereas u-boot has "FM1@TGECn" :

In any case have tried both ETH2 and ETH2 connected directly to my PC and to a network switch. In neither case can not get device to work either from Linux or u-boot. From linux:

Both ports have alternating flash link/activity lights, which sort of looks like some sort of device error status?

Are ports on PC and switch 10G?

Both the ports are 1GB.

It is required to connect T2080 10G port to another 10G port or 1G to 1G.
