HI Ake and Simon:
I set callback function as following, but have to call netif_set_link_up/down to trigger the callback function.
Once cable is unplugged / plugged, the netif_set_link_down/up should be called by one times. I don’t know how to do this…
I can use the ETH_GetNetifUporDown function to get the Ethernet link status (not lwIP link status), but where to put it ?
Would you help me
static uint32_t ETH_GetNetifUporDown (void)
{
return (ETH_ReadPHYRegister(PHY_ADDRESS, PHY_BSR) & PHY_Linked_Status) ? 1:0;
}
------------------------------------------------------------------------------------------------------------------------
void lwip_link_callback(struct netif *netif )
{
if (netif_is_link_up(netif))
{
printf ("link status go to up \r\n");
dhcp_start(netif);
netif_set_up(netif);
}
else
{
printf ("link status go to down \r\n");
dhcp_stop(netif);
netif_set_down(netif);
}
}
Set the call back function in lnit_lwip()
…
netif_add(&netif, &ipaddr, &netmask, &gw, NULL, ðernetif_init, &tcpip_input);
netif_set_default(&netif);
netif_set_link_callback(&netif, lwip_link_callback);
…

Hi!
I think that is something you define in your ethernet driver. My approach is to send a signal to a separate task to handle the cable-plug/unplug events. In the task I currently
disable dhcp (if active) on cable-unplug signal and reenable it on cable-connect. it might be good to set an auto-ip when unplugged as well, but I'm not sure. Maybe it should be handled with the netif_set_up/down-functions instead, I'm still experimenting...

No, I'm not sure why you need any of your sockets to be non-blocking.
