Hey guys, After implementing the lwIP driver for my platform, I am starting it with the following instructions:
struct netif *netif=(struct netif *)malloc(sizeof(struct netif)); > ip_addr_t ipaddr, netmask, gw; > IP4_ADDR(&ipaddr, 192, 168, 0, 24); > IP4_ADDR(&netmask, 255, 255, 0, 0); > IP4_ADDR(&gw, 192, 168, 0, 1); > netif_add(netif, &ipaddr, &netmask, &gw, NULL, LWIP_driver_init, > LWIP_driver_input); > netif_set_default(netif); And I am trying to ping the address 192.168.0.24 from 192.168.0.1 and the result is Destination host unreachable. I attached the lwipopts file for more info. Can you please tell me if there is something that I need to do to "start" lwIP's functionality? Thank you in advance, Angel C
