thanks a lot
What steps should I follow to configure ethercat?
cnc@raspberrypi:~/Desktop$ ethercat slave
bash: ethercat: command not found
cnc@raspberrypi:~/Desktop$ sudo geany /etc/ethercat.conf
cnc@raspberrypi:~/Desktop$ sudo systemctl enable ethercat.service
Failed to enable unit: Unit file ethercat.service does not exist.
cnc@raspberrypi:~/Desktop$ sudo systemctl start ethercat.service
Failed to start ethercat.service: Unit ethercat.service not found.
cnc@raspberrypi:~/Desktop$ sudo systemctl status ethercat.service
Unit ethercat.service could not be found.
cnc@raspberrypi:~/Desktop$ sudo chmod 666 /dev/EtherCAT0
chmod: cannot access '/dev/EtherCAT0': No such file or directory
cnc@raspberrypi:~/Desktop$ ethercat slaves
bash: ethercat: command not found
cnc@raspberrypi:~/Desktop$

Hi
after installing the official LinuxCNC ISO for Raspberry Pi 5
I realized that the screen resolution is not good,
it is not manageable and there is no audio,
it will surely be fixed.
so I tried installing LinuxCNC + EtherCAT on native Raspberry OS
I installed kernel 6.6.45-rt39-v8-16k+ with inspiration from here
for EtherCAT drivers I entered the keys for the repositories from here
and followed Rod's guide here here
Everything works
latency, maybe a little high
I was wondering if it depends on the kernel and if it is possible to modify it in some way
many Thanks

what does uname -v report?
Seems you don;'t have a RT kernel

If you want instructions to create a PREEMPT_RT for Raspberry Pi 5 with native Raspberry OS you can see at this link
forum.linuxcnc.org/9-installing-linuxcnc...pi-5?start=40#303696
or use the ready-made image you find here
forum.linuxcnc.org/9-installing-linuxcnc...pi-5?start=40#303752
Then follow the procedures already described for Ethercat drivers

hi
here is the report with uname -v
no RT, yet it works, something went wrong
which kernel is working?

Latency is OK, so the kernel should work just fine.
No idea if it works for EtherCAT though, although in general should work if the same headers are used.

Thanks so much!
in the meantime
i tried to understand what went wrong and i found the reason,
i skipped a step in menuconfig
with that step the compilation of the RT kernel was successful
the latency is now very ok
unlike the installation of the EtherCAT packages that gives me an error
i don't know what it depends on, maybe we need to wait for Etherlab to update the repositories
