Category: EtherCAT
Is it safe to say the Linux Raspberrypi 6.12.11 #1 SMP PREEMPT_RT doesn't work with Etherlab Ethercat Master version 1.6.2. Trying to setup EtherCat on Pi5 with Debian.
I have issues starting the ethercat service.
sudo systemctl enable ethercat
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.
Here's what shows in the journal
Feb 05 12:13:12 raspberrypi ethercatctl[53739]: ERROR: No network cards for EtherCAT specified.
Feb 05 12:13:12 raspberrypi ethercatctl[53739]: Please edit /etc/ethercat.conf with root permissions and set MASTER0_DEVICE variable to either a network interface name (like eth0) or to a MAC addre>

Looks like some files are missing or can't be found when trying to install the modules?
sudo make modules_install
returns

This seems to the affect other command later like sudo modprobe ethercat. When this run it returns
modprobe: FATAL: Module ethercat not found in directory /lib/modules/6.12.11
Almost looks like the module never gets built or compiled correctly?
EtherCAT's kernel module (.ko) doesn't appear in the modules when trying to search for it
sudo find /lib/modules/$(uname -r) -name "ethercat.ko"
This returns not found
I think tomorrow I'm just gonna try everything again with an old kernel version, just to get started.
