Papilio Duo Ethernet Communication Issues


Recommended Posts

I could manage to assign IP address to the Arduino ethernet shield mounted on Papilio Duo board, But when I tried to establish communication using TCP/IP, collision was detected by the ethernet shield. I think it must be because of the common SPI bus shared by both AVR microcontroller and Xilinx FPGA. Is there any work-around solution of the problem?

I used Ethernet library from Arduino IDE. At present Xilinx FPGA is disabled, but in next stage I will be using wishbone bus shared registers.

I have never tried out the ethernet shield with the Papilio DUO so not sure what the problem is that you are running into... If you load a blank circuit to the FPGA side then there should not be any conflicts... 

You could also try to use one of these types of ethernet modules:
