Start_CAN on startup #397

JochenDeprezVintecc · 2024-04-23T12:25:28Z

@owzagj Is there some kind of service we can enable so the Start_CAN command gets executed on boot. This way the CAN interfaces are immediately active.
I get the point of not enabling them if you do not need them.
But I suppose most use cases with the owa5x will require them so being able to enable them from startup would be quite nice.

owzagj · 2024-04-24T15:43:47Z

Hi @JochenDeprezVintecc there are several possibilities depending on your development approach:

You may run a script from inside a container which sets the Start_CAN command. This link maybe useful.
You may remount the BalenaOS filesystem as R/W, create a systemd service which runs "Start_CAN 1" and then enable it.
You may build a BalenaOS custom image using this repo and adding your own startup configuration.

Hope this helps! Any question don't hesitate to ask!

JochenDeprezVintecc · 2024-05-07T16:03:06Z

Hi, I have currently fixed this by creating a custom systemd service. But as far as I understand, this service will disapear if I do a HostOS update. So for production purposes I will probably need to build a container to do the Start_CAN command. I have downloaded a package from your developer zone. But I run into problems with having the wrong c++ compiler.

I also am looking into the GPS, will I have to follow the same steps to start GPS? Like build a container and run the command to start it? Because I see no command on the HostOS to start GPS

owzagj · 2024-05-09T08:15:50Z

Hello @JochenDeprezVintecc, thanks for your question.

Regarding the c++ problems, could you please give me some more feedback about the nature of the problems? Maybe a log would be helpful.

About the GPS, let me check and I'll come back to you ASAP.

Thanks in advance!

Hi, I have fixed some issues with the c++ compilation but when trying to run make on the ow5x_AN8 module I downloaded from the developer zone I get the following error:

root@4fd5059:/rtu# make

Building owa5x_AN8 Object

JochenDeprezVintecc · 2024-05-23T09:48:04Z

When building the owa5x_AN3 I seem to be able to run the make command but then on execution of the binary I get also an error to libRTU_Module.so

root@4fd5059:/io# make

owzagj · 2024-05-24T13:25:11Z

It seems your toolchain is lacking that library. May you give me an email so I can send them to you?

They should be located in /usr/lib/owasys and /lib/

Thanks in advance

Hello @JochenDeprezVintecc did you have the chance to test the libraries?

Please let me know, I'm here to help!

Hi, the libRTU errors seem to be gone, now I have some other errors:

When running the owa5x_AN3 from within a container, I get the following error:
root@4fd5059:/io# ./owa5x_AN3
Enter owa3x_AN3 version(0.0.2) program
All external Control functions loaded

Error 43 in RTUControl_Start()...
20240530-141324 UnloadExternalLibrary() ok
20240530-141324 UnloadExternalLibrary() ok

Also when running the Start_CAN binary from within my container, I get the following error:

root@4fd5059:/# ./Start_CAN 1
No shared library /lib/libGSM_Module.so foundlibasound.so.2: cannot open shared object file: No such file or directory

It seems to be the same kind of error with the socket communication

My container is running in privileged mode though

JochenDeprezVintecc · 2024-06-11T09:32:24Z

Hi @owzagj, any idea how I could resolve the socket communication error?

owzagj · 2024-06-12T09:19:29Z

Hi Jochen, You have to map the sockets from the native rootfs into the container's. Try this workaround in the container definition file: services: myservice: volumes: - hosttmp:/tmp volumes: hosttmp: driver_opts: type: none o: bind device: /tmp Also in dockers containers you can: 1. Run the container in priviledge mode: * $ docker run --privileged -d whatever 2. Map the rootfs * docker run -v /sys:/sys -d whatever 3. To access the RTU lib map the sockets /tmp/PMsck, /tmp/Tmsck You can find info in this links: https://stackoverflow.com/questions/58113780/access-shared-library-inside-a-docker-container https://docs.balena.io/learn/develop/hardware/ BR Álvaro Guzmán Juán R&D Engineer [Logotipo Descripción generada automáticamente] Phone: (+34) 946 025 323 E-mail: ***@***.******@***.***> www.owasys.com<http://www.owasys.com/> Bizkaia Technology Park, 202 E-48170, Zamudio Bizkaia Spain This email and any attachment may contain confidential, propietary or legally priviledged information.

owa5x_HW_Docker_setup A

To achieve a easy deployment for a big number of Owa devices, it is a good idea to use docker images, due to the ease of setup on a new device and the posibility of deploying in a bulk using Docker Compose.

In this tutorial is exposed how to create a new docker container and how to set it up so it comunicates with the rest of HW modules in the Owa. For the purpose of this tutorial an Owa_5x running FW_1.1.0 has been used.

Requisites

Docker installed on the Owa:

Refer to the tutorial on the official website: https://docs.docker.com/engine/install/debian/

Creating docker image

The next command will create a docker container with debian with access to corresponding sockets.

docker run -v /tmp/PMsck:/tmp/PMsck -v /tmp/TMsck:/tmp/TMsck --privileged -it debian

Installing required libraries

Once on the command prompt inside the container, take the container_id, which is displayed on the hostname part of the command prompt.

Open another terminal on the Owa and run the following commands to install the Owasys libraries inside the docker container.

##RUN IN OWA TERMINAL
docker cp /lib/libFMS_Module.so d1d9beb4e833:/lib/
docker cp /lib/libGPS2_Module.so d1d9beb4e833:/lib/
docker cp /lib/libGSM_Module.so d1d9beb4e833:/lib/
docker cp /lib/libINET_Module.so d1d9beb4e833:/lib/
docker cp /lib/libIOs_Module.so d1d9beb4e833:/lib/
docker cp /lib/libRTU_Module.so d1d9beb4e833:/lib/
docker cp /lib/owasys/ d1d9beb4e833:/lib/
docker cp /usr/lib/aarch64-linux-gnu/libasound.so.2 d1d9beb4e833:/usr/lib/aarch64-linux-gnu/
docker cp /usr/lib/aarch64-linux-gnu/libasound.so.2.0.0 d1d9beb4e833:/usr/lib/aarch64-linux-gnu/

Installing your script/program on the container

Last thing is to install the program so it can be executed inside the docker container, in this tutorial Start_BT_WiFi will be used for demonstration purposes.

##RUN IN OWA TERMINAL
docker cp /usr/bin/Start_BT_WiFi d1d9beb4e833:/usr/bin/

Running the program

Once the previous steps are completed, the container can be used as if it was the Owa.

##RUN IN DOCKER CONTAINER
root@d1d9beb4e833:/ Start_BT_WiFi 1
BT/WIFi ENABLE OK

##Dmesg OUTPUT
[ 6121.652336] BT: Loading driver

Hello @owzagj - I have the same problem, I would need to start can from the docker application.

I can copy the libraries to the docker image but the issue is with socket communication. Balena does not allow bind mounts.

Trying to mount the sockets with:

volumes:
  - /tmp/PMsck:/tmp/PMsck
  - /tmp/TMsck:/tmp/TMsck

Gives you an error from Balena: Bind mounts are not allowed.

Could you please advice on how to overcome this?

otlaitil · 2024-10-07T06:55:46Z

I suggest we would always start CAN on boot: #545

As discussed in balena-os#397 starting CAN communication from within balena docker applications is difficult due to needing owasys libraries in the image and needing to mount sockets to the running container. This commit enables CAN on boot. Changelog-entry: Start CAN on boot
