Ethercat installation from repositories - how to step by step

I think it's time to update the first post of this thread, It's not working straight forward anymore even with 2.9.3, I had to jump on the last post to find a way to let it work. Also tried 2.9.4 and it's not working. Thanks for your time, when it works It's so satisfying

the only reason why Cornholio used 6.12 kernel was to get the latest kernel in the hope that support or the Pi5 was better but the earlier one was pretty good anyway. The default Debian uses kernel 6.1 so it is bleeding edge. Ethercat includes custom kernel components so it might not work on the bleeding edge.
