Hello Andreas,
I installed DKMS for Ubuntu 22.04 with
"sudo apt-get update" and "sudo apt-get -y install dkms".
I can now find several dkms directorys and files.
After I rebooted the system I tried to start ethercat-master with "sudo
systemctl start ethercat", but I got an errormessage:
Job for ethercat.service failed because the control process exited with
error code.
See "systemctl status ethercat.service" and "journalctl -xeu
ethercat.service" for details.
"journalctl -xeu ethercat.service" gave out this:

I checked if the ethercat.conf file in /etc is not modified but it is,
and all other ethercat -files that could be modifed are modified too.
I dont know why it wont start anymore now.
I deleted the old files EtherCAT and PDServ at /home/user, but that was
after the error occurred.
"please do not use the local path, they are the rest of your manual
installation"
How can I be sure im not using the /local- Path?
I didnt know how to generate the code for my Simulink Model so I had to
search it. I found out that my Matlab 2014b with Student Licence is
missing the "Code Generation"-Tab in the Configuration Parameters of the
model and that if you are using a Student version liense, MATLAB Coder
and Simulink Coder can only be running MATLAB R2016a or later.
Is there any other way to generate the code for the model besides
installing a later Matlab-Version?
Regards
Henrik
