    Board does Not Support LAN Speed 100Mb/s.

      Hello Everyone;

       

      We have developed our own board based on quark x1000 soc in which we have used  the DP83848JSQ Ethernet Phy IC. We have been got the reference design from Galileo Rev2 Board. We have only one change is RJ485 Connector.

       

      RJ485 Connector Details:

      Ethernet part no:J0011D21BNL

       

      Our board is work with Ethernet speed of 10Mb/s but does not work with the 100Mb/s.

      Testing Process:

      1) On Board Boot up auto-negotiation is ON so default speed is set the 100Mb/s. but does not send any packet to remote server which was connected with the board over LAN.

      2) We have set auto-negotiation is OFF and speed is 100Mb/s using the ethtool. but still does not send any packet to remote server which was connected with the board over LAN.

      3) We have set auto-negotiation is OFF and speed is 10Mb/s using the ethtool. it will send and receive packets over LAN.

       

      Please help us to solve or debug more about the above issue as soon as possible.

      Thanks in advance.
