UPDATE: The first post has been updated following upstream changes. It also covers addidional steps required to build DKMS drivers if you have Secure boot (UEFI) enabled on your PC. 

Hi Rodw,

I tryed the steps in the update post. Everythings looks fine till the install ethercat-master.
After 'sudo apt install ethercat-master' i get E: Unable to locate package ethercat-master.

Did you create the /etc/apt/sources.list.d/ighvh.sources file?
did you do sudo apt update?
What distro are you using? Bookworm? or another?

Hi Rodw,

Thank you for the very fast respond, i've been struggling for already more than a week to get a working rpi4+linuxcnc+ethercat. I did this several times with several distro's ans several notes. The rpi4 with linuxcnc under -rt is running, installing the needed ethercat despite without result. As i want to retrofit a 3+2 axis milling machine i want to use more profession drives with ethercat.

So here is the info:

Yes, i created the /etc/apt/sources.list.d/ighvh.sources file. I copied the shown data as instructed.

Raspberry Pi 4 Model B Rev 1.5

Linux rpi4-20230612 6.1.0-10-rt-arm64 #1 SMP PREEMPT_RT Debian 6.1.38-2 (2023-07-27) aarch64 GNU/Linux

I don't think the Pi is supported in the EtherCAT repos anymore. You may be able to build from source. That explains why it can't find an appropriate package. Go to their main site and read carefully. Its all described there and on their git.

It matters less to me to use Raspberry Pi or "PC" based system. I like to build on a solid foundation. So that I can at least go ahead with this for a while. I am a novice on Linux but want to learn to can use LinuxCNC. But i have to be honest i will be never an expert.

What would you advise given the future of LinuxCNC?

Thanks in advance.
