ethernet Issue with BBB-Red

[Guru raj.M]

Hi,

i am using new BBB-Red industrial grid board..i am trying up the BBB with my carrier card with external power supply which is workling absolutely perfect with my old BBB-black board..

 my carrier card with external power supply have 4 isolator Serial digital isolator (Si8422) for 4 UART. 

my BBB-Red loaded with with Debian GNU/Linux 7.8 (wheezy) os and made to boot from SDcard and image date is BeagleBoard.org Debian Image 2015-03-01.

lsb_release -a

No LSB modules are available.

Distributor ID: Debian

Description:    Debian GNU/Linux 7.8 (wheezy)

Release:        7.8

Codename:       wheezy

i am trying to troubleshoot i found this

 dmesg | grep eth0

[    5.623106] net eth0: initializing cpsw version 1.12 (0)

[    5.628425] net eth0: phy found : id is : 0x7c0f1

[    5.633516] net eth0: phy 4a101000.mdio:03 not found on slave 1

[    5.665388] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready

There is not ethernet connetion, such that i am not able to ping to any IP and i am not able to do ssh to / from the device BBB-red, but this same carrier card with external power supply working fine in BBB-Black which have same OS.

Plz can any any tell me what will be the wrong..????

thank you
