Hi,

             I am using ti8148 EVM evaluation board, when I am connecting both the Ethernet cables only one eth0 is coming up of the command ifconfig -a and eth0 interface is working fine . I have tried to up the eth1 by the command ifup eth1 and ifconfig eth1 <> netmask <> up but it is saying no eth1 device is present. Please help to bring up the eth1 interface.

Regards.

    Hi Sudheer,

    Are you using EZSDK 5.05.02.00 / PSP 04.04.00.01?

    When I boot up and try to enable the eth1, I have:

    root@dm814x-evm:~# ifup eth1
    ifconfig: SIOCGIFFLAGS: No such device
    ifconfig: SIOCGIFFLAGS: No such device
    eth1      No such device

    ifconfig: SIOCGIFFLAGS: No such device

    But then when I remove the eth cable and then switch it again I have:

    root@dm814x-evm:~# PHY: 0:01 - Link is Up - 100/Full

    root@dm814x-evm:~# ifup eth1
    ifup: interface eth1 already configured

    Now I can ping the host PC successfully.

    Regards,
    Pavel
