Hello all!<br>I want to use two ethernet interfaces with IP addresses in one subnet. Configuration part of my program is below.<br><br>extern void rtems_bsdnet_loopattach();<br>static struct rtems_bsdnet_ifconfig loopback_config =

<br>{<br>    "lo0",                      /* name */<br>    (int (*)(struct rtems_bsdnet_ifconfig *, int))rtems_bsdnet_loopattach,<br>    NULL,                       /* link to next interface */<br>    "<a href="http://127.0.0.1">

127.0.0.1</a>",                /* IP address */<br>    "<a href="http://255.0.0.0">255.0.0.0</a>",                /* IP net mask */<br>};<br>static struct rtems_bsdnet_ifconfig eth1_config =<br>{<br>    "eth1",                             /* name */

<br>    "<a href="http://255.255.255.0">255.255.255.0</a>",                    /* IP net mask */<br>    ethernet_address1,                  /* Ethernet hardware address */<br>    0<br>};<br>static struct rtems_bsdnet_ifconfig eth0_config =

<br>{<br>    "eth0",      /* name */<br>    RTEMS_BSP_NETWORK_DRIVER_ATTACH,    /* attach (ARM EMAC) */<br>    &eth1_config,                       /* link to next interface */<br>    <a href="http://192.168.1.47">

}; (ethernet_address0 and ethernet_address1 are different) But i got following error: "Can't set eth1 address: File exists" And after that eth0 working only. Help me, please. Thanks.
