I had some troubles with this as well. But I used an older version of lwIP. Search the lwIP mailing list. This is a known problem, and it has been solved by several people.

Hi, finaly I got my HW :-) Arp works fine. Then I tried ping and got no reply. I tracked the problem down to ip_input(). There the packet is matched against an interface and this fails. ----------- /* unicast to this interface address? */ if (ip_addr_cmp(&(iphdr->dest), &(netif->ip_addr)) || /* or broadcast on this interface network address? */ ip_addr_isbroadcast(&(iphdr->dest), netif)) { ----------- iphdr->dest and netif->ip_addr are the same! But iphdr->dest is at address 0x80302F0A and is not dividable by 4. The dsp truncs the address to 0x80302F08 and so the compare fails. Any idea what can be done about this? Here is my lwipopts.h: ----------- #define MEM_ALIGNMENT 4 #define LWIP_DHCP 1 #define LWIP_NOASSERT #define NO_SYS 1 ----------- TIA Gustl _______________________________________________ lwip-users mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/lwip-users _______________________________________________ lwip-users mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/lwip-users
