In this next section describes the steps to create the Simple Socket Server using Nios II. We create a 
new project in Nios II using the project template, Simple Socket Server. The PTF file created using 
the SOPC builder in Quartus II is used in the Select Target Hardware section. 

 

Figure 4-8 Nios II Project Simple Socket Server 

After the project is created, open network_utilities.c to modifty the flash section which uses flash to 
store  the  MAC  address.  Since  the  demonstration  uses  DE3  host  board  which  doesn‟t  have  flash 
memory,  the  flash  portion  of  the  code  can  be  commented  out  shown  in 

Figure  4-9

  as  well  as 

inserting our own Mac Address.
