Thanks for the qsys files,but it is SSRAM+Flash,and
i wanted to see sdram+flash,very simple simple qsys design as u depicted in screenshot (Nios II + sysid+sdram+flash+tristate bridge).

Please see the attached zip file containing a reference design for Cyclone III NEEK that uses
sdram +
external flash memory +
triple speed ethernet components. This design should work on the NEEK without modification.
Just download the zip file and extract to your C: drive root directory. Double-click on the
niosii_ethernet_standard_3c25.qpf file to launch the Quartus II design. Open the Programmer within Quartus and change the file to the niosii_ethernet_standard_3c25.sof (it may be pointing to a different directory that does not exist). Program the NEEK, then launch the Nios II SBT for Eclipse to create software.
I suggest creating an app based on the Memory Test example software to test the Flash memory.
If you are really bold, you can download the Simple Socket Server Design Example located at:
http://www.altera.com/support/examples/nios2/exm-hello_world.html You must follow the instructions very carefully to get the SSS example to work, but with the proper finesse, it will work on the NEEK with the attached hardware design.
Good luck, and have fun with this...
