Ethercat installation from repositories - how to step by step

Have you tried to rebuild the ethercat modules after upgrading the kernel? And are the corresponding headers also installed (linux-headers-6.1.0-18-rt-amd64)?

Hello everyone,

Can anybody help me because when I type it says that there is no such file or directory

 

Sorry, I missed a command
mkdir ~/dev
I amnot sure where scott is with his cia402 support as this may become redundant.

Thank you,

everything worked, now i can move on 

thank you, I do step by step according your guidance, It seems everything is ok, i also got the same result.
can you advice me or give me an link on how to set up an system with Ethercat servo after that, it seems only Stepconf.Wizard and Pncconf.Wizard. thank you
