Ethercat installation from repositories - how to step by step

Thanks so much!



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

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

If you compile a custom kernel or build an ISO or image, the headers are not going to be in the repositories.
They are built with the kernel. If you don't save or install them, you will need to build them again.
The 2.9.3 isos and images  do all of this for you.
Your posts  have nothing to do with installing ethercat from repositories, so please ask further questions on another thread.

so, the moment of victory was very short. i followed the instructions to the letter, did some corrections when needed and had the first signs of a lcnc-ethercat system coming alive (that was last week) yesterday i wanted to continue but i only got the error screen from linuxcnc telling me that it closed down because some pin doesn't exist ... cia402 pin... wanted to share xml and hal and ini and screenshot but after writing the reply at work with all attachments ... it refused to submit... waited half hour to submit... nothing happened.
so, here's what i have for hardware :
1 rtec IO 1616
1 rtec ECR86 for X
1rtec ECR86 for Y
2 wantai nema 34 steppers (60V-3.5Amp) {these steppers eat almost 6 amps in real-life}

had every sign that the install was complete last week ... saw a lot of lcec pins in the halmeter. actually was able to turn on an output on the IO card. yesterday nothing . no lcec pins, only error screen about this cia402 pin does not exist...
of course i already tried to do everything possible ... reload this, reconfig that, recompile this... for some reason i can't the lcec pins back like i had last week... 

Start linuxcnc from the command line, read the error about the missing pin. It probably tells you the line number. Comment it out until Linuxcnc starts and review halshow to get the right spelling/pin name. This is just basic trouble shooting, not ethercat related.

linuxcnc -l 

is a very handy command (Lower case -L)

I got error when i try to install  ethercat in rpi5 

Can you try this image?

Thank you. yeah its working now . But it doesn't contain ethercat in it, is it..?

yes should have ethercat repos set up so follow the sticky

Hello everyone

I am getting the same error with a new install of LCNC 2.9.3 on amd64. (Also affects my 2.9.2 install)

sudo apt update

Etherlab repository not valid anymore? Any ideas?

Edit: I have found rods image here which works:
