I have done the following steps to add the On-Chip memory to receive the incoming UDP packet.

1. Add an On Chip Memory (6553) through SOPC builder.

2. Generate the System

3. Compile the Nios-II Processor

4. Do the Desire Changes in IPPORT.H file (please see the attached ALTERA_PKT_MEM file this is the desire section of ipport.h file). This changes is as par readme file from the Ethernet_Accel_Design.Zip (Title: enabling the fast packet memory optimization)

5. After that I run the code on nios processor: and resultant nothing happen I mean TSE_MAC not initialize etc totally blank console. Otherwise it shows the initilize the tse_mac, outo_negtation, then simple_socket starting up, ip address is 192.168.1.205 etc

6. Is my SOPC connection of descriptor memory is properly connected or something missing…?

7. Do I add something in Nios BSP editor as this packet memory visible in BSP Editor?
