I also got initially excited, but then after studying specs, it appears that ConnectOne modules support only RMII connection. Smaller Coldfire chips (5223x, 5225x) have only MII. So, no direct connection as ETH PHY is possible. To connect it as PHY transceiver, appropriate shim would be required. For example two additional PHYs: one talks MII to Coldfire EMAC, then TX/RX connection between PHYs, then second PHY talks RMII with ConnectOne module. Quite a waste of resources.</BODY></HTML> Tue, 06 Oct 2009 16:11:41 GMT https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/Wifi-PHY-device/m-p/175190#M6759 MichalKonieczny 2009-10-06T16:11:41Z
