AM261-SOM-EVM: PROFINET device example running with 1 PHY.

Part Number: AM261-SOM-EVM
Other Parts Discussed in Thread: SYSCONFIG

Hello!

I am trying to run the Profinet device example from TI industrial communications SDK (I tried both versions 10.02.00.17 and 2025.00, the same behavior was observed) on my AM261x LaunchPad revision E2. I had some initial issues like missing EEPROM data (MAC address for example) that I managed to resolve, but now the PN stack start up is stuck during the PHYs initialization. I can't provide more detailed debugging info, because the stack is delivered as a library and I don't have the sources. One thing that is specific for my set up is that I have only one PHY. I modified sys config and selected NONE for ETH PHY 1, but I still see that the stack library is calling the initializations functions for both PHYs. I suspect that this is the reason the stack start up is failing. Shortly, my question is - is it possible to run the example on 1 PHY with just sys config settings changes, or additional changes are needed in the TI stack?

  • Hello,

    Thanks for your inquiry!

    for the time being, our PROFINET stack is precompiled to support 2-port devices. It is not possible to simply change that from sysconfig.
    Please reach out to your regional sales representatives for customization of standard deliveries.

    Kind regards,
