Ethernet connection with an embedded linux board

Development Boards MicroMod
1

Hi , I’ve bought an embedded OLIMEX linux board powered by an AT91SAM9260 ARM processor which has an ethernet port.

I 'd like to download files over ethernet using TFTP protocol from a host PC (equipped with ubuntu 8.04 ) to the embedded board but I don’t know how to do it.

I own an ethernet cross cable and when I plug it both to the PC and the board on the bar I see a notification that says “wired network connection”.

The home page of the board manufacturer is :

http://www.olimex.com/dev/sam9-L9260.html

and the user manual of the board is:

http://www.olimex.com/dev/pdf/ARM/ATMEL/SAM9-L9260.pdf

I don’t know how to discover the IP address of my laptop to issue commands like wget to download in the embedded board the files compiled in the laptop pc with a C cross compiler .

Please , can somebody give me some advice?

Thank you very much in advance.

On the Ubuntu box, run “ifconfig” (or “/sbin/ifconfig”) to list all your network interfaces and the addresses they have. “arp” will show the ethernet addresses currently known to be on the same network.

When I give ifconfig i get this:

Could you please tell me now how I can go on to configure the eth0 port please?

Thank you very much.
