STM32MP257x-EV1 TSN/Ethernet Not Working

[user_ABCD]

Hello -

I have the STM32MP257x-EV1 up and running the base image. I have included the layers for the Ethernet switch and TSN. I am trying to understand the embedded Ethernet Switch better. I am working with the assumption that I can plug in two endpoints to ETH1 and ETH3 with no interaction from the MPU and pass ethernet traffic (e.g., ping).

But this does not work from the get-go. Is there something that needs to be done to enable it?

Hello, Here is the network config after you applied the linux expansion for tsnswch. There is no application so you have to do it manually. For ex, if you assign IP 192.168.0.20 on the PC plugged on ETH1, you will be able to ping sw0ep or ping another PC plugged on ETH3 with a static IP set to 192.168.0.30. If Then you want to test ETH2, you can assign end0 a static new network IP address and activate IPforwarding on the board.

This article will be updated soon to give more.

Was there any updates or thoughts on this?

[Bernard PUEL]

did you try to set IP address like I advised ?

[Bernard PUEL]

It seems your default network configuration is wrong, so need to check why ....

As described in wiki the network config is set thanks to this script = /usr/sbin/ttt-ip-init-systemd.sh 

So try to apply manually the config and check what is failling.

This service will not start, nor does running the script manually work.

Could you please share a photo of your board (taken from above)

I can try rebuilding and re-flashing the board. Is there any place that a complete TSN image is posted that is known-good that I could download and flash? I don't believe the starter/distribution, etc. have these in them/

[Bernard PUEL]

In term of HW all seems ok.

A starter package with tsnswch will be available soon on st.com. I will generate one and share it to you this afternoon.

Your image appeared to work fine as far as bringing up the interfaces. Therefore, I am beyond hurdle #1, but still have issues. I will dig into the TSN data some more to understand why my simple use case in the picture above does not completely work.

I believe I got this working, thank you for the support.

This is good news !!
