Altera TSE driver and example program for lwIP (1.3.2)

very very unfortunately,billa and every one,my problem also exists.

so I describe my question again:

my fpga is ep3c120f484 and epcs64,have not supply extern sdram by using quartus 9.0+nios 9.0

i do the project as the "readme txt",and the sopc builder system and nios libirary properties will upload in the picture.

my ip and mac set:

# define STATIC_IP IP4_ADDR(&lwipStaticIp,219,245,66,185)

# define STATIC_NM IP4_ADDR(&lwipnetmask,255,255,255,0)

# define STATIC_GW IP4_ADDR(&lwipgw,219,245,66,254)

# define STATIC_DA IP4_ADDR(&destAddr,219,245,66,112)

alteraTseNetif.hwaddr[0] = 0x00;

alteraTseNetif.hwaddr[1] = 0x1C;

alteraTseNetif.hwaddr[2] = 0x23;

alteraTseNetif.hwaddr[3] = 0x17;

alteraTseNetif.hwaddr[4] = 0x4A;

alteraTseNetif.hwaddr[5] = 0xCB;

and the udpsend:

char udpdata[] = "UDP has Initialed successfully, begin to transfer!\r\n";

struct pbuf *psend;

struct udp_pcb *UdpPcbS;

psend = pbuf_alloc(PBUF_RAW, sizeof(udpdata), PBUF_RAM);

psend->payload = (void *)udpdata;

if (!psend)

{

printf("Can't allocate buffer.\n");

}

UdpPcbS = udp_new();

if (!UdpPcbS)

{

printf("udp_new() failed.\n");

}

udp_bind(UdpPcbS, &lwipStaticIp, 67);

if (udp_bind(UdpPcbS, &lwipStaticIp, 67) != ERR_OK)

{

printf("udp_bind() failed.\n");

}

udp_connect(UdpPcbS, &destAddr, 67);

if (udp_connect(UdpPcbS, &destAddr, 67) != ERR_OK)

{

printf("udp_connect() failed.\n");

}

while(1)

{

udp_send(UdpPcbS,psend);

mSdelay(1000);

mSdelay(1000);

mSdelay(1000);

}

when I debug step by step,the error will be appear in the code in "ip.c"

IPH_TTL_SET(iphdr, ttl);

if (ip_addr_isany(src)) {

ip_addr_copy(iphdr->src, netif->ip_addr);

} else {

(iphdr->src).addr = (*src).addr;

}

and return error.

and it is not caused by compiler optimization.

I can not receive and send any packets.
