OpenCN detailed documentation

Hi Guys,

My name is Nadim Khan,

I have been working in Industrial Automation for last 10 years. My experience is working on PLC, HMI, Servo motion controls, Robotics etc.

Presently from last 1 year or so I have been more curious to learn and handson more about realtime operating systems. I tried freertos untill now.

I came across OpenCN and wanted to learn more but cannot find detailed documentation. For a new joiner like me who has little exposure to this OS world its difficult.

If you guys agree then I am willing to contribute to making and updating the documentation in English with more pictures and so on. So that a new person like me can get along easily.

For preparing document, I will try handson on the openCN, understand its working and prepare document with a step by step procedure there by doing handson as well.

My idea is to update the document such that it becomes easier for new comers like me to try out.

Better and updated the document will make this more popular.

Hi Nadim,

Thanks you for your interest in OpenCN !

The documentation is still a work in progress and we try to update it as much as we can as soon as we have some free time. Thanks you very much to propose your help on this subject !

I think it would be very nice to have someone exterior to help us update the documentation, since we tend to make documentation “by deb”/“for dev” and we definitely need a better userguide .

I guess you already found the sphinx documentation : — OpenCN 2021.2.0 documentation
A good starting point to run OpenCN is here : 8. User guide — OpenCN 2021.2.0 documentation
And if you want to help with the documentation, you can take a look at :
8. User guide — OpenCN 2021.2.0 documentation
13. Development flow — OpenCN 2021.2.0 documentation

I think it is not properly specified in the documentation, but the only bus we support for now is EtherCAT. I’m quit curious to know what kind of hardware you have at your disposal !

Also, I think you have to be registered as a “developper” to contribute, it’s holiday time here but please reach out to @rossierd with your gitlab account so we can put you in the loop.

Of course, feel free to ask us anything, I would happily try to help you in the process !

Hi @Xavier ,

Thanks for the reply. I am very much excited for this journey.

Let me give a brief about what I have.

  • I am planning to contribute 10 hours in a week to this initially and can do more once I get along
  • First and foremost thing I have is a desire to learn and contribute to community project related to RTOS or motion
  • I have experience writing programs in IEC 61131-3 languages and ‘C’ for PLC and motion control programming
  • I have basic knowledge of G codes for motion and robots
  • I have some hands on building embedded Linux from yocto and open embedded layers
  • I am learning python and c language at advance level to grow more.

From hardware point of view. I have below hardwares which I procured for assisting my learning :slight_smile:

  • I have access to windows PC (obviously capable of running linux)
  • I have STM32 microcontroller
  • I have raspberry pi 4 hardware
  • I have other Single board computers’ evaluation Kit from Toradex which can also run embedded linux.

I would like to know from you that are there any specific skill I need to learn to work upon to do testing and documentation?

Regards
Nadim

Hi @NRK,

To my knowledge you have all the basic skill to properly contribute to the project !

Regarding the hardware, OpenCN support 3 physical and 2 virtual plateform : 4. Environment — OpenCN 2021.2.0 documentation

I advise that you make yourself a dual-boot with a linux to compile/run OpenCN. (kubuntu distro is nice if you are familiar with Windows for shortcut etc…)
You can already try to run OpenCN in simulation mode and build/run the GUI (x86-qemu is faster than virt64).
By default, the Micro5 HAL configuration start at boot. (5 axis micro milling machine we have at HEIG)
FYI : From our experience, if you aim to develop component in OpenCN, it is always better to test it on a real hardware, especially when improving anything regarding the motor/spindle command.

Regarding your PLC/C programming skills : Nice ! For now we only have a PLC running C code : 5.9. Machine Logic (PLC) — OpenCN 2021.2.0 documentation

About more technical stuff :
I’ve recently recompiled OpenCN from scratch with a fresh distro (Kubuntu v22.04 LTS) and had some trouble when following our user-guide. I’ve updated the package needs on branch #178 (only tested by myself, need to be checked by someone) : doc/src/user_guide.rst · 178-e2c-opencn-m5-validation-bug-list · mecatronYx / OpenCNC / opencn · GitLab

Have fun !

Xavier

Hi Xavier,
I setup my PC and tried to build first image following below link
https://mecatronyx.gitlab.io/opencnc/opencn/user_guide.html
I followed the procedure to build openCN image for qemu x86. but in the middle i face an error as below.

This error is related to version mismatch of library.
Is it something faced before? Am i missing some steps or doing something wrong?
I first want to build and run an image so that i can know better and move ahead.

Hi Nadim,

Thanks again in your interest in OpenCN.

First the installation procedure was made for Ubuntu 20.04.

The build error is related to Cap’n Proto: you should install version 0.7.0
Here is the build procedure. It came from Cap’n Proto web site adapted to 0.7.0 version:

Please first remove the current installed version of this tool.

curl -O https://capnproto.org/capnproto-c++-0.7.0.tar.gz
tar zxf capnproto-c++-0.7.0.tar.gz
cd capnproto-c++-0.7.0
./configure
make -j6 check
sudo make install

Hope this helps.
J-P

Oh, In your previous post you suggested Kubuntu so i went ahead with Kubuntu.

I will try the procedure Ubuntu again.

Once I sucessfully build and run openCN on qemux86 then I will mention all the steps that i followed and all versions in my document that I am preparing.

Regards
Nadim

Hi Nadim,

sorry, I was not clear. Kubuntu is a good choice. I just want to inform that the documentation is made for Ubuntu 20.04 and there is some point that has to be adapted with newer version.
You can keep the Kubuntu, no problems.

Based on the log you shared, if you update Cap’n Proto, it should fix the issue you reported.

Hope this helps

opencn/agency/usr/target/components/ocno/
the above path contains a file named ocno.cpp, on line 162, there was a " ` " due to which my compailation threw error. I removed that and rebuilt the image.
Compilation completed 100%.

Now when i try to run using using below commands
$ cd <OPENCN_HOME>/agency
$ ./st

I get error

nadim@nadim-pc:~/opencn/agency$ ./st
./st: line 1: #!/bin/bash: No such file or directory
qemu-system-x86_64: -hda /home/nadim/opencn/agency/filesystem/sdcard.img.x86-qemu: Could not open ‘/home/nadim/opencn/agency/filesystem/sdcard.img.x86-qemu’: No such file or directory

Am i still missing something? I cannot see any sdcard.img.x86-qemu at the given location.

Thanks and Regards

Great if you were able to compile the framework ! (I will fix the compilation error).

Once the compilation is completed, the next step is to deploy it.
the steps are, from agency folder:

  1. ./deploy -f It formats the SD card or create it in emulation case
  2. ./deploy -a It deploys all components (kernel, rootfs, apps) in the SD card

You can get the help of this tool: ./deploy -h

Hope this helps

I will try this step.
I thought that the deploy steps are for real devices only so i skipped this step and tried to start qemu emulation directly.

I will try and update you.

Qemu booted: below log of boot.

My quick doubts are

  • Will qemu’s ip is 127.0.0.1 localhost ip address or i can find exact ip somewhere else? Once I have IP then i can move ahead with SSH and other explorations.
  • To run host application, can i run it on same pc on which qemu is running?

When trying to build host application i get below errors :blush:

  • Can you please also guide me whether i need to export any environment variable like we do in standard embedded Linux build or I can directly open a new terminal and build the host application?

Hi Nadim,

Something when wrong at the end of the boot process. I’ve to check what is going on here.
To let you continue investigating OpenCN framework, you can do the following:

  • Comment all lines in agency/rootfs/board/common/rootfs_overlay/root/start_opencn.sh
  • Rebuild rootfs. From agency folder do ./build.sh -r
  • Deploy rootfs and apps: ./deploy -ru`
  • Start again OpenCN → You should arrive up to the opencn prompt

Hope this helps

Regarding the error during the build of the host apps: It seems your system is missing QT5.

Here are the package you should installed: sudo apt install qtbase5-dev

Hope this helps
J-P

Continuing the discussion from OpenCN detailed documentation:

This solution worked.
Below is the first login and ifconfig command on qemu:

I will redo the whole procedure on Ubuntu version because its what i use for other work also. I will redo and then get in touch with you for documentation discussion of what i did till now. My plan is to make such a document under guidance of you guys which is more interactive with pictures so that any new user can build openCN framework for all platforms and have a feel of what it is.

Great that the boot went well !

Can you share the content of micro5/micro5.hal ?

  • the boot issue seem related to it

Thanks
J-P

iI am very sorry to say I am using vi editor and its not able to paste contents out of editor so i am unable to copy the contents. can you tell me the path where all qemu files are stored host pc?

Below are the contents of root.

m5_kin_param.txt micro5_initcmds_tsdZS.xml
micro5.hal micro5_setup1.hal
micro5.ini micro5_setup1_with_plc.hal
micro5_ec_topology.xml micro5_startup.sh*
micro5_initcmds_tsdXB.xml micro5_test.txt
micro5_initcmds_tsdYC.xml tool.tbl

I’d like to see the file present on the target.

Once you started OpenCN with the st command, you can type the following command from the prompt: cat micro5/micro5.hal
