Ethernet connection on T1040RDB evaluation board

[steffendedekind]

Hi all,

I currently try to "quickle" run some indivdual test and benchmark code on the T1040RDB evaluation board I currently have. Unfortunately the currently installed kernel does not include any coepages needed to use MMC cards or USB sticks. And I have no clue how to get the network working - there are several interfaces:

root@t1040rdb:~# ip link show

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

2: fm1-gb0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UNKNOWN mode DEFAULT qlen 1000

    link/ether 00:04:9f:03:3a:97 brd ff:ff:ff:ff:ff:ff

3: fm1-gb1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UNKNOWN mode DEFAULT qlen 1000

My cable is connected to "ETH0" (labled on the eval boards case) - but even if I bring up fm1-gb0-4 with different IPs (and the default route is also present, MAC addresses are properly set) I'm not able to connect or ping the board. If I try a "ping" in the uboot promt it tries different interfaces (FM1@DTSEC2, FM1@DTSEC3, FM1@DTSEC4) and it tells me finally

Using FM1@DTSEC4 device

host 192.168.1.1 is alive

On Freescales homepage I haven't found any useful documentation.

Anyone can help with this?

Seems to be solved in the moment of writing :smileywink:

If I noticed correctly one has to use "ifconfig ...up" before plugin the ethernet cabe! Otherwise around it does not work.

root@t1040rdb:~# ifconfig fm1-gb3 192.168.1.23 up

... plug in ethernet cable ...

root@t1040rdb:~# ifconfig
