[lwip-users] Assertions when using DHCP when using LWIP 2.0

[Neerav Patel]

Hi

I am running into two assertions on starting DHCP.  They are the following:

Assertion "dhcp_create_msg: dhcp->p_out == NULL" failed at line 1774 in src/core/ipv4/dhcp.c

Assertion "dhcp_create_msg: dhcp->msg_out == NULL" failed at line 1775 in src/core/ipv4/dhcp.c

code I use to start lwip is the follows:

   IP4_ADDR(&gw, 0,0,0,0);

   IP4_ADDR(&ipaddr, 0,0,0,0);

   IP4_ADDR(&netmask, 0,0,0,0);

   ....

   netif_add(&ethernet_netif, &ipaddr, &netmask, &gw, NULL, ethernetif_init, tcpip_input);

   netif_set_default(&ethernet_netif);

   netif_set_up(&ethernet_netif);

   dhcp_start(&ethernet_netif);

Can someone shed some light into why I am running into this? 

Thanks in advance.
