Ethercat installation from repositories - how to step by step

Rod,

I don't have time tonight to check things out, but when trying to install Ethercat I was getting the NO PUBKEY error, so think the KEY needs updating.

This had to have just happened as I did a quick build of Bullseye with a 2.9 RIP and had no problem a week ago for a different controller. Plus did 2 builds on Buster last month. I am completely overloaded with work, so will not have any time to check things out on Andreas openSUSE page but will check back in case you get to it first. I was going to double check with another Buster build, but don't have time. Just wanted to put it out there in case others are having a problem with the error.

Thanks,
Robert

I had issues too. It seems  some of our Debian repos have been disabled by one of their users. But if you click through, the debs seem to be available for download. You might need to  register as a user ( I am) 
build.opensuse.org/repositories/home:bon...ce:EtherLab/ethercat

Rod,

Ok I decided to go and compile the code from the "official" IgH EtherCAT site that Florian, Richard, and Andreas maintain.  I just finished a bit ago, but just wanted to say it was still there and working.  I haven't done it this way since way back with Wheezy.  After EC-Debianize I never wasted time on compiling as it was just too easy... "sudo update-ethercat-config".

I will check out the DEB in a few days as I just wanted to ease my mind that it could be done still.  Plus, this is the official code just like Andreas had on the repo.  I was getting nervous there for a second as I have too much time and money in our equipment.  Glad to see the "ethercat-master". 

Thanks,
Robert

Robert,  I am not across what you did

did you just

Odd they show that on their site but no build instructions so do you just  follow this?

@rodw / all: did it every work for you to upgrade the kernel on a running EtherCAT system?

I wanted to give Kernel 6.3 a try ...Kernel works, but dkms fails to build the EtherCAT driver for 6.3

Seems like there is already a merge request pending to address this:

I have modified the source code cdev.c and dkms was able to build the driver.
