Going from DE2 to DE2-115 Ethernet

[Altera_Forum]

So I successfully developed my code on the DE2 board to working, essentially it's a variation on BTXSistemas' DE2_Net to introduce some randomization and other features. However I now need to implement it on the DE2-115 which has a much different Ethernet core. I'm trying to use the Web Server example as a starting point but it's so much higher level than I really need that I'm getting nowhere. Basically what I need is to figure out the equivalent function of  

 TransmitPacket(TXT,Length)  on the DE2-115. Can anyone help me out here? Thanks in advance and I've included my main code below.  #include "alt_types.h" // alt_u32 # include "altera_avalon_pio_regs.h" //IOWR_ALTERA_AVALON_PIO_DATA # include "sys/alt_irq.h" // interrupt # include <stddef.h> # include "sys/alt_flash.h" # include "sys/alt_flash_types.h" # include "sys/alt_alarm.h" // time tick function (alt_nticks(), alt_ticks_per_second()) # include "sys/alt_timestamp.h" # include "sys/alt_stdio.h" # include <fcntl.h> # include "nios2_ctrl_reg_macros.h" # include <io.h> # include <stdio.h> # include <unistd.h> # include <stdlib.h> # include <string.h> # include "LCD.h" # include "system.h" # include "DM9000A.C" # include "hello_led.h" # include "test.h" unsigned int aaa,rx_len,i,packet_num, times, counter; unsigned char RXT; unsigned char SND; // Payload buffer unsigned int IPsource_1,IPsource_2,IPsource_3,IPsource_4; unsigned int IPdestination_1,IPdestination_2,IPdestination_3,IPdestination_4; unsigned int IPchecksum1,IPchecksum2,IPchecksum3,IPchecksum4,IPchecksum5; unsigned int Mac_source1, Mac_source2, Mac_source3, Mac_source4, Mac_source5, Mac_source6; unsigned int Mac_dest1, Mac_dest2, Mac_dest3, Mac_dest4, Mac_dest5, Mac_dest6; unsigned int times, lenght_h, lenght_l; unsigned int flenght, IPlenght_h, IPlenght_l, data_lenght, IPlenght; unsigned int delay, Mode; int data0, data1, data2, data3, data4, data5, data6, data7; int main(void) { LCD_Test(); IPsource_1 = 0xC0; // Assign ie: 192.168.0.44 IP for the DE2 IPsource_2 = 0xA8; IPsource_3 = 0x00; IPsource_4 = 0x2C; IPdestination_1 = 0x??; // Insert your IP data here IPdestination_2 = 0x??; IPdestination_3 = 0x??; IPdestination_4 = 0x??; Mac_dest1 = 0x00; // Insert your MAC address data here Mac_dest2 = 0x03; Mac_dest3 = 0x25; Mac_dest4 = 0x43; Mac_dest5 = 0x6A; Mac_dest6 = 0x27; Mac_source1 = 0x01; // Assign a MAC address for DE2 Mac_source2 = 0x60; Mac_source3 = 0x6E; Mac_source4 = 0x11; Mac_source5 = 0x02; Mac_source6 = 0x0F; delay = 0; Mode = 0; data_lenght = 1468; // Maximun Data lenght 1468 bytes flenght = data_lenght + 0x2E; //Total packet lenght lenght_h = ((data_lenght+8) & 0xFF00)>>8; // Convert in H byte and L byte lenght_l = ((data_lenght+8) & 0x00FF); IPlenght = data_lenght + 8 + 20; // IP Lenght for IP header IPlenght_h = (IPlenght & 0xFF00)>>8; // Convert in H byte and L byte IPlenght_l = (IPlenght & 0x00FF); // Calculating the IP checksum IPchecksum1 = 0x0000C511 + (IPsource_1<<8)+IPsource_2+(IPsource_3<<8)+IPsource_4+ (IPdestination_1<<8)+IPdestination_2+(IPdestination_3<<8)+(IPdestination_4)+ (IPlenght_h<<8) + IPlenght_l; IPchecksum2 = ((IPchecksum1&0x0000FFFF)+(IPchecksum1>>16)); IPchecksum3 = 0x0000FFFF - IPchecksum2; IPchecksum4 = (IPchecksum3 & 0xFF00)>>8; IPchecksum5 = (IPchecksum3 & 0x00FF); srand ( time(NULL) ); unsigned char TXT = { Mac_dest1,Mac_dest2,Mac_dest3,Mac_dest4,Mac_dest5,Mac_dest6, //Destination MAC Mac_source1,Mac_source2,Mac_source3,Mac_source4,Mac_source5,Mac_source6, //Source MAC 0x08,0x00, //Type 0xFF, // Header Length 0x22, //ECN-CE 0x33,0x44, //total Length 0x55,0x66, //Identification 0x77,0x88, //Fragment Offset 0x99, //Time to Live 0xAA, //Protocol 0x55,0x66, //Checksum IPsource_1,IPsource_2,IPsource_3,IPsource_4, //Source IP //0x77,0x88,0x99,0xAA, //Source IP IPdestination_1,IPdestination_2,IPdestination_3,IPdestination_4, //Destination IP 0x99,0xAA,0x55,0x66,0x77,0x88, //Data 0x55,0x66,0x77,0x88,0x99,0xAA, //Data 0x55,0x66,0x77,0x88,0x99,0xAA, //Data 0x55,0x66,0x77,0x88,0x99,0xAA, //Data 0x00,0x00,0x00,0x20,0x99,0xAA}; //Data unsigned char TXT2 = { Mac_dest1, Mac_dest2, Mac_dest3, Mac_dest4 ,Mac_dest5, Mac_dest6, Mac_source1, Mac_source2, Mac_source3, Mac_source4, Mac_source5, Mac_source6, 0x08, 0x00, 0xFF, 0x22, IPlenght_h, IPlenght_l, 0x55, 0x66, 0x77, 0x88, 0x99, 0xAA, IPchecksum4, IPchecksum5, IPsource_1, IPsource_2, IPsource_3, IPsource_4, IPdestination_1, IPdestination_2, IPdestination_3, IPdestination_4, 0x04, 0x00, 0x04, 0x00, lenght_h, lenght_l, 0x00, 0x00}; for (i = 0; i < 42; i++) // Load the TXT in the SND (ethernet packet).

Hi driscoll42, 

did you get any result from this project. could you please tell us the out come if there is any.

No, sorry. I never got it working properly.
