Linuxcnc's Ethercat in Raspberry pi-5

I am using raspberry pi-5 for my project to build linuxcnc . I actually build linuxcnc from source file following this site ( linuxcnc.org/docs/master/html/code/build...nc.html#sub:realtime ). and  i also build ethercat using this two ( forum.linuxcnc.org/ethercat/49771-etherc...ce-full-instructions   // forum.linuxcnc.org/ethercat/42048-notes-...at-on-raspberry-pi-4 ). but at stage of testing i am facing issues in ethercat . i attached that error below .   

I'm not really sure if ethercat is supported on the Pi5 as the Pi 5 was released just after Linuxcnc 2.9.1 was released
Can you try  using the pi5 image from the downloads page and burn the image to a SD card using Balena Etcher.
It has the ethercat repository already installed.
So then follow the Sticky I wrote in this section to install ethercat from the repositories
if that works, the issue is with your build.

Thank you . Yes, Its working good with linuxcnc2.9.2 image file. But Actually i want build linuxcnc and ethercat from source that only i can able to modifies it for different UNIX device for later. could you share with me any reference for build linuxcnc and ethercat from source file.

Just be careful cross compiling isn't easy (if not quite possible) for Linuxcnc.

Funny how some things are in the documentation, below links to how to build linuxcnc from source. Be aware the build deps will install Apache2. Ahh the beauty of debian\ubuntu

I've successfully built LinuxCNC by following the instructions in the official documentation. Additionally, I've compiled EtherCAT using the instructions provided on this site.( forum.linuxcnc.org/ethercat/49771-etherc...ce-full-instructions ) However, when I reached the final testing step for EtherCAT, I encountered an error while executing a specific .ini file. Here is a screenshot of my sytem configration :

Could you help me troubleshoot this issue?

All lscpu gives is info on the cpu, nothing else is reported, and it's really not the info needed.
You haven't given any indication of your error your error, I skipped mind reading & ESP classes at school

Please upload the error Linuxcnc is giving and all the files, ini, hal & xml & any extra files your ini file loads. Screenshots aren't really much help, ever tried using grep to look for a string in a screen shot ? Just a little joke there mate.

Put up the right info and you'll get the help you want.
