Hello, when i started a project with BBB i noticed that my ethernet not working , i don't really now if it's hardware or software problem, because i never used it until now(internet over usb was enough). So any ideas how to fix it ? 

My dmesg : 

eth0: initializing cpsw version 1.12 (0)
[   97.431262] net eth0: phy found : id is : 0x7c0f1

Did you try to flash a recent image? http://beagleboard.org/latest-images
For latest BBB I (Rev. C) would recommend http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#BBB_Rev_C_.284GB_eMMC.29

My BBB was not working out of the box. The "latest images" end of Fabruary also made problems. But the actual one is working fine. You can update the kernel and the confirguration after flashing to your needs.
