    Hi,

    Can you provide more context to your problem

    1. What is that you are trying to do ? Which cores are operational and which OS is running on which core ?

    2. Which SDK and version are you using ?

    3. What software are you using ?

    4. Please provide your network configuration diagram

    In general, to route between ports you would have to configure the ALE. Refer to this guide for more details

    Regards

    Hi,

    Sorry for the delay. Are you still looking for a solution ?

    I am assuming that you have the basic switch working and you and you can receive packets in RTOS and QNX. In which case, you need to configure ALE to forward packets between the ports. If you are sending a unicast packet from RGMII 5 to RGMII 6 then you don't have to do anything as the switch learns the destination by itself.

    If you want to do any specific configuration then you can take a look at this FAQ
