ttory hi

I'm sorry to interrupt, but I was wondering if this is possible to do via a
usb port???

I modified src code like this

=================================================================\
/* Set ICMP header */
  ICMPBUF->type = ICMP_ECHO;
        ICMPBUF->icode = 0;

  if(ICMPBUF->icmpchksum >= HTONS(0xffff - (ICMP_ECHO << 8))) {
    ICMPBUF->icmpchksum += HTONS(ICMP_ECHO << 8) + 1;
  } else {
    ICMPBUF->icmpchksum += HTONS(ICMP_ECHO << 8);
  }
        ICMPBUF->id = 0x842f;
        ICMPBUF->seqno = 1;


        /* Set IP header */
        ICMPBUF->vhl = 0x45;
        ICMPBUF->tos = 0;
        ICMPBUF->len[0] = 0;
        ICMPBUF->len[1] = 0x54;
        ICMPBUF->ipid[0] = 0xf2;
        ICMPBUF->ipid[1] = 0x9c;
        ICMPBUF->ipoffset[0] = BUF->ipoffset[1] = 0;
        ICMPBUF->ttl = 128;
        ICMPBUF->proto = UIP_PROTO_ICMP;
        ICMPBUF->ipchksum = 0;
        uip_ipaddr(ICMPBUF->destipaddr, 128, 134, 64, 123);
        uip_ipaddr(ICMPBUF->srcipaddr, 128, 134, 64, 132);

        //uip_process(UIP_TIMER);

        uip_len = 98;
        nic_send();
=================================================================\



But I can't see my packet be sent from target board.

The rule what I know
1. set data in uip_buf
2. calc uip_len
3. nic_send()
Is this incorrect way?

Can you see your packet with wireshark?
If yes, are all the packets (ETH, IP, ICMP) correct?
Where does your test fail?

Regards
