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?

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

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

Ok no issue. Sorry but I don't see what could be the issue. What is the result of these 2 cmd below on your side ?

root@stm32mp2:~# cat /sys/class/net/end*/address

10:e7:7a:e3:b8:e2
root@stm32mp2:~# cat /sys/class/net/sw*/address

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 !!
