Cyclone IV GX Transceiver Nios MAC

I am using the Cyclone IV GX Transceiver Starter Board and Quartus 12.1. 

The Qsys or SOPC tools seem straight forward on implementing the FPGA portion. 

 

The Nios II EDS provides a starter template project for Simple Socket Server.  

The Template description indicates the requirement for a lan91c111 Ethernet MAC. 

I don't have this hardware on the kit. 

 

I searched the examples provided with the kit but did not find any code/examples 

for the NiosII portion. 

 

Is there a simple poject for the Nios II EDS compatable with my kit that would serve as a starting point? 

 

My target application is a data acquisition implementation that will initially forward data via UDP protocol. 

 

Any help appreciated.

I located the BoardTestSystem - BT_General project in the kit examples folder. 

When I try to compile the Quartus project, I get the following warnings. 

Warning (15709): Ignored I/O standard assignments to the following nodes 

Warning (15710): Ignored I/O standard assignment to node "L0_led" 

Warning (15710): Ignored I/O standard assignment to node "local_rstn_ext" 

Warning (15710): Ignored I/O standard assignment to node "pcie_rstn" 

Warning (15710): Ignored I/O standard assignment to node "refclk"

Warning (15710): Ignored I/O standard assignment to node "rxp" 

Warning (15710): Ignored I/O standard assignment to node "tx_out0" 

Warning (15710): Ignored I/O standard assignment to node "txp" 

I have located these identifiers in the Assignment Editor. Not sure why they are there. 

 

Finally, I get the following Error. 

 

Error (170012): Fitter requires 903 LABs to implement the project, but the device contains only 900 LABs 

 

I am trying get to the point where I have a working example for the Simple Socket Server as a starting point. 

 

Any guidance appreciated:-)

I reduced the original ram size in the example from 16384 to 10240. 

program builds and loads. Successful run of Simple Socket server 

from example.
