WARP Project Forums - Wireless Open-Access Research Platform

Hi,

we are currently trying to connect a Warp V3 Board with an arduino over Ethernet (using the Ethernet Shield 2 http://www.arduino.org/products/shields … t-shield-2).

While this should not be a problem, what we are currently observing is the following:
1.) Both ETH-Ports of our Warp Implementation (which was based from version 1.5 of the Reference Design) can connect fine to any PC/Switch we have tried so far (as long as the fixed, hardcoded speed matches)
2.) Connecting the Ethernet shield to a switch/PC works fine aswell
3.) Once we however directly connect the Arduino to one of the WARP Ethernet ports, no connection is made. On WARP side, all 3 Indicator lights stay lit up (2x red, 1x green), and on arduino side no indicator lights light up (which indicates no connection at all). As a consequence, nothing can be transmitted.
This behaviour stays the same, independent of defined ETH-Speed (10/100/1000 MBit)
4.) Running the 1.7.0 Reference Bitstreams, we observe the same behaviour + no connection.

Our guess so far is that this is caused by the rather static Ethernet configuration utilized in the xaxiethernet module. However, we don't know which additional configuration parameters we could try apart from the speed.

Do you know what could cause this + what additional configuration we could try?

Thanks
