Once  MAC  address  is  generated,  Autonegotiation  is  initiated  where  both  connected  devices,  the 
Ethernet (Marvel 88E1111) and Gateway devices broadcasts its transmission parameters, speed and 
duplex  mode.  By  default,  the  MAC  Interface  for  the  Ethernet  Device  is  set  to  RGMII.  In  this 
demonstration,  we  are  using  GMII  MAC  interface  which  can  be  configured  through  the 
management interface of the 88E1111 Ethernet device. 

 

Figure 4-14 88EE111 Device Interface 

Block Diagram in 

Figure 4-14

 shows the MAC interface options and supported media types for the 

HSMC-NET  board. It  supports  copper  media  interface  which  is  connected  to  an  RJ-45  connector 
though magnetic supporting physical media for 1000BASE-T, 100BASE-TX, and 10BASE-T. 
 
Once  the  link  is  established  an  IP  address  is  assigned  to  the  Ethernet  device  along  wit h  the  port 
number.  Through  the  TCP  and  port  number,  the  demonstration  uses  Telnet  client  to  establish 
connection with the Simple Socket Server, where it is continuously listening on the port. Once the 
connection  is  established  between  the  Telnet  client  and  Simple  Socket  server,  the  Telnet  client  is 
able  to  send  packets  which  are  received  by  the  Nios  II  processor  and  through  the  Simple  Socket 
Server it will send server command to the DE3. The packet sent contains LED command which is 
extracted and dispatched to the LED command queue for processing by the LED management tasks.
