Tool/software: Linux

Hi

i want to use the DP83869 in our project, we need to have copper and fiber PHY with automatic switching between them based on signal detection of SFP module.

an overview to your responses to other posts, shows that you are preparing the Linux driver, i want to know when it would be ready to release, because we really need the device in our project.

thanks

    The PHY does not support automatic switching for copper and fiber based on signal detection.

    You will need to switch through register access.

    We are currently working on a driver for the device and it will appear in our ETHERNET-SW product page when available.

    Dear Ross

    Thanks for responding

    I know that automatic switching is not supported on the chip, but i think that using a GPIO would help us to detect a signal from SFP module.

    So if the driver read the GPIO status, it's easy to change the register setting according to the signal detect.

    Anyway, if the gpio method is not used in the driver, it would be a good idea to have something to test the chip with our soc.

    If you share the driver draft it would be helpful so

    Any further notice would be appreciated

    Sincerely
