Ethercat installation from repositories - how to step by step

hi
here is the report with uname -v

 

no RT, yet it works, something went wrong

which kernel is working?

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

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


 

Try installing those one by one.

hi
Thanks @tommylight and @elovalvo
these are two paths that I have already taken without success
the headers for the kernerl 6.6.45-rt39-v8-16k are not found.

Now I'm going away for a few days, when I come back we'll see

thanks a lot
