Hi all, I have tested on simulation that i am able to send the data through Txethmac as the nibbles is coming out from it. The only problem is that when it comes to real test, i am unable to capture the packets from computer. Does anyone face this problem? I am currently testing it on Spartan3E board using SMSC LAN83C185 for the PHY chips. -- View this message in context: http://www.nabble.com/Question-on-Ethernet-Mac10-100-Mbps-tf3956772.html#a11227322 Sent from the OpenCores - IP Cores mailing list archive at Nabble.com.
