Re: [lwip-users] lwip 1.4.1 -> 2.0.1: problem with dhcp

no, you just need to enable the interface during system startup by calling netif_set_up().

NO_SYS example:

Thank you for your answer.

I don't really understand that point. Do I have to change my InitEthernetAdapter function like that?

 

// Start with dhcp

if (_useDhcp)

{

  if (dhcp_start(&_netif) == ERR_OK)

  {

    netif_set_up(&_netif);

  }

}

Thanks

Markus

Maybe this is missing:

http://www.nongnu.org/lwip/2_0_x/upgrading.html
 

 * Changed netif "up" flag handling to be an administrative flag (as opposed to the previous meaning of    "ip4-address-valid", a netif will now not be used for transmission if not up) -> even a DHCP netif    has to be set "up" before starting the DHCP client
