My port consists of mainly the implementation of sys_arch.c and the interface
to the ethernet chip (With a seperate rx task, interrupt driven). After setting
up the ethernet chip I do the following operations to init lwip:
IP4_ADDR(&gw, 192,168,1,11);
IP4_ADDR(&ipaddr, 192,168,1,34);
IP4_ADDR(&netmask, 255,255,255,0);
sys_init();
mem_init();
memp_init();
pbuf_init();
netif_init();
tcpip_init(NULL, NULL);
netif_add(&nif, &ipaddr, &netmask, &gw, NULL, ethernetif_init, ip_input);
netif_set_default(&nif);
netif_set_up(&nif);
Anything missing?
