    Hi,

    It might be possible to switch the two interface names using udev rules and information from the DTS. We will take a look but please note this is outside of driver support that TI provides.

    Best Regards,

    Hi,

    After reviewing the issue we currently do not see a way to switch the port names. To be able to change the pin mux for example would require each signal name of the two ports be interchangeable between the two CPSW ports. Each Ethernet RGMII signal for an interface only goes to one pin.

    From what we can tell udev rules would not be applicable here as the CPSW driver is expected to be built into the kernel and is not supported as a loadable module. 

    Best Regards,
