we have already tested the PI 4 with CODESYS SP14 and run into problems.
Configuration:
Runtime SP14
Fresh Raspbian Buster (updated this morning on the latest version)
RPi 4 with 1 GB RAM
After the installation of the runtime via the CODESYS IDE, the runtime starts and is running for a short time. After a few seconds the codesys task is gone. Same thing after a reboot of the system.
It would be great if you can send us information how to get it running. We want to use Pi 4 and CODESYS with out PiXtend PLC devices as soon as possible.
Kind regards!

I have started it using Putty and watched it run on TOP from the Pi terminal.
It runs for about 10 seconds the drops off.
Im running V3.5 SP16.

Thanks for the reply. Yeah i can start and top codesyscontrol from the pi terminal and i have removed it and reinstalled it. i can see it dropping off on TOP
it is a 32mb image you can extract to sd card with program called hddraw

I met Edwin today, a friend of yours, he helped me today. Let me know if you need anything! I have the CNC working pretty good, I have extra drives if you are interested.
Hi!
I am vey curious also! We would like to see pictures and video of your setup ;-)
Plus, it's a bonus if you share your experiences here on forge with instructions on how to build a CNC machine using PI4? Personally I am very interested in such a project !

That is a mighty setup you have built. Very cool to see a Raspberry Pi act as brains of the setup. The drives work via EtherCAT or Profinet?
I have also have written/translated some nifty projects with help of the community here, like CfUnit, an open source and free unit testing framework of which we are very proud! Maybe you'll use it someday?
It supports assertion of 3D array's of all datatypes https://forge.codesys.com/svn/prj,cfunit,code/landingpage/index.html?raw
So, I was hoping that would share your software with us if you wish, as I'd very much want to build such a CNC machine myself.On the servo's, I have some lying around here allready, so at this moment I am not interested.
Hope you will consider sharing the software with the community.

I do not really know whether I should create a new post or I can just ask here. I am trying to use Raspberry Pi 4 with CoDeSys 3.5.16. Actually everything is going ok, until I restart the raspberry pi. The application doe not run. The codesyscontrol is running, also the codesysedge. When I do sudo service codesyscontrol stop and after that sudo service codesyscontrol start, then everything going back to ok. I can see the webvisu and also go online with the development software. The codesyscontrol and codesysedge are from version 3.5.16.
Please advise me how to make this working. Thank you in advance.
What version of Linux are you running? I know I had trouble and would have

I use swissbit 16Gb. Usually I get no problem with this card.
What do I find strange is that I can just stop and start codesyscontrol service and everything is ok. So I think it is some kind of timing issues.

@davewkoenig
Super interesting project. Unfortunately I can't justify buying any servo drives right now.
What do I see connected to the raspberry pi 4? Is that the Opto IO?
Did you use USB boot or network boot to get around SD corruption issues? Or just having a spare SD card on hand?
Did you use a codemeter USB key for storing those licenses?
Are you willing to share your program? Sorry I ask because it looks like you were above. I don't want to use it I just want to look at it and learn. I've never done any motion control work.
@januar Could it be an issue with Codesys starting before all the drivers have booted? I've heard about that before but not encountered it myself.
@kumareasu For using a Beaglebone Black you might be able to use IO cards that have drivers for Codesys intended for Raspberry Pi if you shift the I2C from 5v to 3v using logic level shifters. You could maybe design a converter cape decently easily for something like this. For instance https://sequentmicrosystems.com/index.php?route=product/category&path=20 The industrial IO card doesn't say it has Codesys drivers but there are, you just don't get access to PWM or the communication bus's.

The latest CODESYS build (3.5.14.30) as of this post does not recognize the new Raspberry Pi 4 Build B when scanning the local subnet. It has a new OUI and the prefix is DC:A6:32.
I can confirm that with the Buster build (Version:July 2019, Release date:2019-07-10), the runtime briefly executes, then terminates.
any news about the PI4 with codesys

With 3.5.15.10 release date is 19th this month - these buster problems will be solved.

Hi Edwin,
Just tried running my Pi4 . Getting issues with the runtime stopping after a few seconds. I can connect to the Pi again if i start the runtime from the Update Pi tool.
I have started it using Putty and watched it run on TOP from the Pi terminal.
It runs for about 10 seconds the drops off.
Im running V3.5 SP16.
On my PI4 this works anything special?
we need the /tmp/codesyscontrol.log or maybe better stop the runtime and start it manually by:
sudo /etc/init.d/codesyscontrol stop
then for the multicore version
cd /var/opt/codesys
sudo /opt/codesys/bin/codesyscontrol_armv7l_raspberry.bin -d /etc/CODESYSControl.cfg
for the singecore version
cd /var/opt/codesys
sudo /opt/codesys/bin/codesyscontrol_armv6l_raspberry.bin -d /etc/CODESYSControl.cfg
Maybe a corrupt application or application with a bug lead to a crash on startup - remove it by the runtime deploytool(use disable application)?

Thanks for the reply. Yeah i can start and top codesyscontrol from the pi terminal and i have removed it and reinstalled it. i can see it dropping off on TOP

the logfile does not help in this case..
Is this what your looking for ?

Thank you Edwin
Hi,
but is this really RASBIAN Buster?
This is a different OS image isn't it?
Hi Edwin,
Yes my mistake for some reason the image file was the wrong one . I downloaded buster and installed it . The run time is working perfectly now.
thanks for your help.
Dear,
Would you tell me which version that you downloaded?
because now i am facing the same problem..
thanks!
I am using Pi4 for 3-4 months on my CNC machine, it runs great! Did have some problems in beginning, using Debian version.
I can send you an image if you like? I use wiFi to connect to my router at Ethernet port for EtherCAT coms.
