Is that current version? Bullseye?

Yes, it is.
What I don't understand is that the same version works fine on Pi4 revision c03111/c03112.
I read on the forum, I believe, that the problem is similar to what happened some time ago and solved with the v4.4 version of the runtime.
But of course this is my guess....

Hi,
I have to point out that the problem is not related to the bulleye version.
The same problem also occurs with the buster version.

Hello,

Let me present my problem, and let's see if it's similar
Just got a PI4B. used Raspberry PI imager, put on the latest OS(bullseye 32bit)
Enabled SSH.
From Codesys v3.5 SP18 installed the runtime on the PI(runtime V4.7), no problems so far, so i reboot the PI using the codesys reboot target command
When i tried to go online with the PI, it says that the target can't be found and i need to rescan the network
If i rescan, i can't find my PI
If i send a stop command and then a start command to the runtime from codesys via SSH, and then i rescan the network, i find the PI adn i can go online.
point is, that sometimes after a few second, and sometimes instantly after going online, i get the same error that the target can't be found.

other than that, i haven't tried anything else, but more than a year and a half ago, i used the first time a Raspberry pi 4B with codesys and it worked like a charm. but i can't remember how i did it and what OS and runtime versions i used.

and i have no idea what to do right now.

follow up

i just realized, that while installing the runtime on the PI, it asks me to automatically install an edge gateway, i click ok, and it's the same story if i try to go online using the localhost gateway or the gateway with the PI ip address
and the message when i try to go online is "no connection to the device. Please rescan your network."

when i clicked system information i noticed this
"2023-02-17T17:36:07Z, 0x0000001c, 4, 28, 0, **** ERROR: Invalid session ID. Still other sessions on this channel, do not close it."

have no idea what it means

check what happens if you start the runtime manually by
sudo /etc/init.d/codesyscontrol stop
then

cd /var/opt/codesys
sudo /opt/codesys/bin/codesyscontrol_armv7l_raspberry.bin -d /etc/CODESYSControl.cfg
for the multicore runtime

for the SL (without MC ) runtime:
cd /var/opt/codesys
sudo /opt/codesys/bin/codesyscontrol_armv6l_raspberry.bin -d /etc/CODESYSControl.cfg

here are the last few lines resulted
the whole text result is in the attached file

2023-02-17T17:58:20.900Z: Cmp=CmpRouter, Class=1, Error=0, Info=1, pszInfo= Setting router <instance>2</instance> address to

sooo the "oops..." message confusez me a lot.

Follow up

i think i called the command for single core
but after calling sudo /opt/codesys/bin/codesyscontrol_armv7l_raspberry.bin -d
i got the same result(correct response in .txt file attached)

could you give the result of 'ifconfig -a' and 'cat /proc/cpuinfo'

sorry for the late reply,
attached are result of the commands requested(Result_2), and also the result of ipconfig on the windows pc that i work on(win_host)

Hi,
attached are result of the commands requested.
ifconfig -> ifconfig_log.txt
cpuinfo -> cpuinfo_log.txt
start runtime (v4.7) -> codesys_log.txt

My logs are very similar to those reported by Theo.
From what I see we are both using the 1.5 Raspberry revision.
Me with 4Gb, Theo with 8Gb.

thanks for the feedback & information, we try to support the Rev1.5 with the next release

thanks for the help also!
to be sure i understand, the problem is with the revision of the PI hardware?
and we hope that in the next version of the codesys runtime the problems are solved?

yes and yes 👍

Hi, since this was an issue on V4.7, i assumed that it would be resolved in V4.8, but unfortunatly, it is still an issue on 4.8. Is there any indications when this will be resolved?

this is a new/other issue:
https://faq.codesys.com/pages/viewpage.action?pageId=153321520 should fix it &
will be solved with 4.9.0.0 release

Same probleme here. Found my Rev1.5 boards work with 2023-02-21-raspios-bullseye-armhf.img and Codesys Runtime 4.8.0.0
