Hello,

The software terminal output shown in your description is coming from a nitchestack application right? My point here is, you cannot run Nitchestack without phy.

The TSE expects a clock to come from the phy. without this clock, you will not get rid of this reset issue.

May I know what is the intention of having phy-less system?

Are you going to send data through ethernet cable?

Thank you.

    Hi,

    I am using Marvell switch.

    This switch has un-managed mode, i.e. mode in which the switch starts operating without any need for configuration.

    I think this is not an issue of nitchestack limitation , I've commented out all it's trials to communicate with phy.

    The limitation seems to be purely related to TSE.

    Thanks
