Notes from installation of ethercat on Raspberry Pi 4

This can be used to control machines when using the RT-Preempt kernel, it can not be used to control machines when using normal "generic" kernel.
RTAI version is more for use with parallel port.

Hi Hakan,
I am using Raspberry pi5. I build Linuxcnc from source code .now i started installing ethercat from source code following your notes but now i am facing some issues in etherlab master build ($make dkms_build) in this line.
i also attached output log. is there any other way for RP5 ..?    

3 years is a long time in this space.
I would try installing the Raspberry pi 5 image on the downloads page and then follow these instructions
forum.linuxcnc.org/ethercat/45336-etherc...-how-to-step-by-step

The ethercat repositories should be installed for you already so hopefully, you will find there is no need to build from source if iGh supports the pi5 now.
 

At the point of "Test ethercat with linuxcnc " i am facing issues like "lFound file(REL): ./ethercat.hal
lcec: dlopen: libethercat.so.1: cannot open shared object file: No such file or directory"
But path my directory (path=$PATH:/usr/local/lib)

you check id uefi or not as rodw explain here: forum.linuxcnc.org/ethercat/45336-etherc...-how-to-step-by-step ??

In my case need (not uefi but have that error because not all libs needed was installed) to install libethercat 2 time second one using synaptic. After it goes ....

Thanks for reminding me of this. This is probably the issue I have with installing ethercat.
