RTL8019AS problem

Posted: Wed Aug 08, 2007 3:29 am

Hello all,

I wrote simple program to test my MMLan2 Ethernet interface based of RTL8019as chip.

Source code is:

Quote:

#include "D:\tempomat_projekt\sieciowka\sieciowka.h"
#include <stdio.h>
#include <stdlib.h>
#include <RTL8019.C>

void main()
{

byte buffor[500];

//ARP frame

buffor[0]=0xff; //broadcast FF FF FF FF FF FF
buffor[1]=0xff;
buffor[2]=0xff;
buffor[3]=0xff;
buffor[4]=0xff;
buffor[5]=0xff;
buffor[6]=0x01; //SENDER MAC ADRESS 01 02 03 04 05 06
buffor[7]=0x02;
buffor[8]=0x03;
buffor[9]=0x04;
buffor[10]=0x05;
buffor[11]=0x06;
buffor[12]=0x08; //TYPE ARP 08 06
buffor[13]=0x06;
buffor[14]=0x00; //Hardware type (ETHERNET) 00 01
buffor[15]=0x01;
buffor[16]=0x08; //PROTOCOL TYPE (IP) 08 00
buffor[17]=0x00;
buffor[18]=0x06; //HARDWARE SIZE 06
buffor[19]=0x04; //PROTOCOL SIZE 04
buffor[20]=0x00; //OPCODE REQUEST 00 01
buffor[21]=0x01;
buffor[22]=0x01; //SENDER MAC ADRES 01 02 03 04 05 06
buffor[23]=0x02;
buffor[24]=0x03;
buffor[25]=0x04;
buffor[26]=0x05;
buffor[27]=0x06;
buffor[28]=0xAC; //sender IP 172.16.0.5
buffor[29]=0x10;
buffor[30]=0x00;
buffor[31]=0x05;
buffor[32]=0x00; //TARGET MAC ADRES 00 00 00 00 00 00
buffor[33]=0x00;
buffor[34]=0x00;
buffor[35]=0x00;
buffor[36]=0x00;
buffor[37]=0x00;
buffor[38]=0xAC; //TARGET IP 172.16.0.2
buffor[39]=0x10;
buffor[40]=0x00;
buffor[41]=0x02;

nic_init(); //MMLan2 init

output_low(PIN_B7); //LED off
delay_ms(15000); //delay (I put it to give time for Lan devices to initialize them- I think this is unnecessary)
output_high(PIN_B7); //Led on (after 15s period)

nic_begin_packet_tx(42);
nic_packet_put_data(*buffor[0],42);
nic_packet_end_tx();

}

The buffor is ARP request. My PC Ethernet interface is configured:
IP: 172.16.0.2
MAC 11:11:11:11:11:11
Mask:255.255.255.0

I execute Wireshark sniffer, but I do not receive any ARP request frame sent by my MMLan2 (Source IP 172.16.0.5 Source MAC 01 02 03 04 05 06).

The nic_init(); executes correctly because PC Ethernet is switched on.

What is wrong??

Or maybe some one have his own test program for RTL8019as???
