TDA4VEN-Q1: Regarding the issue of online switching between 100Mbps and 1Gbps

Expert 2180 points
Part Number: TDA4VEN-Q1

Tool/software:

Dear TI's experts,

We currently have an Ethernet solution and we need your help to evaluate whether it can be implemented:At present, we have implemented gigabit network functionality on Linux. If the phy chip we use can switch between 100Mbps and 1Gbps by modifying the register configuration, does TDA4Ven not need any modifications?

We have verified this solution on other platforms and it is feasible. Currently, we need your help to provide a professional evaluation on the TDA4 platform.

Btw,will implementing Ethernet on Linux use CPSW? I'm not quite sure.

Regards.

    Hi,

    Linux Driver supports the Link speed of 100/1000 by reading from PHY.

    It will automatically get configured by getting link information from PHY, no driver changes required for 100Mbps speed.

    Usually ethtool is a utility to change the link speed at run time. If phy has capability to support multiple speeds.

    Best Regards,
