Simple Socket Server Template can't find mac adress?

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;
