Simple Socket Server Template can't find mac adress?

Browse the Simple Socket Server source code.

In one of the source files (IIRC network_utilities.c) you should find a function named get_mac_addr() or get_board_mac_addr().

Change the function body in order to return a fixed MAC address instead of asking you to enter one.

Regards

comment the entire code of "get_serial_number (void)" , if your board do ot have any serial number.

and then in generate_and_store_mac_addr() assign to ser_num = 1;//get_serial_number();

and then inside if loop assign your own XX value

/* This says the image is safe */

flash_content[0] = 0xfe;

flash_content[1] = 0x5a;

flash_content[2] = 0x0;

flash_content[3] = 0x0;

/* This is the Altera Vendor ID */

flash_content[4] = 0x00;

flash_content[5] = 0x07;

flash_content[6] = 0xED;

/* Reserverd Board identifier for erase boards */

flash_content[7] = 0xXX;//FF;

flash_content[8] = 0xXX;//(ser_num & 0xff00) >> 8;

flash_content[9] = 0xXX;//ser_num & 0xff;

once again in function generate_mac_addr(unsigned char mac_addr[6]) assign one to ser_num = 1;//get_serial_number(); and assign

/* Reserverd Board identifier */

mac_addr[3] = 0xXX;//FF;

mac_addr[4] = 0xXX;//(ser_num & 0xff00) >> 8;

mac_addr[5] = 0xXX;//ser_num & 0xff;

Thank you Cris!As your tips shows for me,I read the function get_mac_addr and get_board_mac_addr().Then i guess the problem may caused by the code below,is it rigth?

if (!error)

{

mac_addr[0] = IORD_8DIRECT(last_flash_sector, 4);

mac_addr[1] = IORD_8DIRECT(last_flash_sector, 5);

mac_addr[2] = IORD_8DIRECT(last_flash_sector, 6);

mac_addr[3] = IORD_8DIRECT(last_flash_sector, 7);

mac_addr[4] = IORD_8DIRECT(last_flash_sector, 8);

mac_addr[5] = IORD_8DIRECT(last_flash_sector, 9);

printf("Your Ethernet MAC address is %02x:%02x:%02x:%02x:%02x:%02x\n",

mac_addr[0],

mac_addr[1],

mac_addr[2],

mac_addr[3],

mac_addr[4],

mac_addr[5]);

}

But i don't know how to change the code properly.Could you give me a little tips?Thank you!

Thank you very much!Yes i get the mac address under your guide!But i also want to know how can i read the mac address from the flash.I test my boad with board_test_system which can read the mac address properly.So is it ture that the mac address still be availble without erasing?Also,i get a problem as below:

AFAIK this is the correct flow of SSS; there isn't any error!

It has stopped because it has indeed nothing else to do, until a connection on port 30 will be requested by a network client.

Thank you very much indeed!

When I use the telnet to connect my simple socket server,it really works!

I am sorry to disturb you again.I meet another problem when i using simple socket server.I use telnet to connect with my project.As the menu shows,When I press 0 then press retrun,I find that nothing happens with led.Could you help me to solve this problem?Because I don't know why.Thank you!

hello,

I am using Simple Socket Server Template for my own triple speed ethernet qsys system in which I modify the NiosII Ethernet Standard Design by replacing DDRx with ssram on my CycloneIV GX150 Development Board.I just build my simple socket server project with the template(RGMII) without anything changed except for the tse_my_system.c.When I run my projec,the NiosII Console display some information as the text below:

Can't read the MAC address from your board. We will assign you

a MAC address.

Please enter your 9-digit serial number. This is printed on a

label under your Nios dev. board. The first 3 digits of the

label are ASJ and the serial number follows this.

:confused:What make me confused is how could i edit the source code to solve the problem of can't find mac address from my board.Could anybody give me some advice?I'm much obliged to you for helping me.

hi,

i have the same problem but at the line above , "ip address of et1 : 192.168.1.80" , it gets stuck and becomes not responding. also it shows 0.0.0.0 in place of the ip address. any idea what can i do?

also do i need to manually enter the ip address, subnet, gateway etc in the following lines:

----->

ip4_addr(*ipaddr, ipaddr0, ipaddr1, ipaddr2, ipaddr3); ip4_addr(*gw, gwaddr0, gwaddr1, gwaddr2, gwaddr3);

ip4_addr(*netmask, mskaddr0, mskaddr1, mskaddr2, mskaddr3);
