Hi @Filippo-GEG

I’ve observed no problem on my side.

Just a major question : did you attach (exec) to your running container before launching the top command ?

torizon@verdin-imx8mp-15229850:~$ docker ps

I think that you did not attach to your running container because you see all the processes of the OS.

Can you verify that you’er attached to your running container, because this would explain that you cannot see your process since it is running inside your container and therefore not visible outside.

Please, let me know.

Sincerely,
François.

Hi @flepron ,

Thanks for the tests.

Regarding the mouse pointer, I haven’t looked into it further at the moment.
Our device also has touchscreen and I am focusing on application development.

I am new to development on SoM and avalonia, and I’m trying to understand if the avalonia framework is right for me or if I should abandon it because it’s too heavy and not very responsive for my device.
I’m still trying to understand the difference between the “Avalonia GTK MVVM” and “Avalonia Frame Buffer” templates and I am studying the Avalonia documentation.

My application will have to be very responsive as it will be used to answer radio calls (Push to Talk).
I was therefore hoping to have indications on which framework/language was recommended for my module, at the cost of having to rewrite my application as long as it is reactive.
I’m afraid I’ll eventually have to migrate to C++, but, at the moment, I’d like to avoid Qt due to the other licensing costs.

Regarding the processes and the top command…
I ran the container on the device in debug using VSCode, and the top command showed my application.
After an hour, when the application no longer responded to clicks, the top command no longer showed my application.
I think the application crashed but continued to show on the screen.
I’ll continue with the tests.

Thank you for your time François.
Let’s see what comes out.

Best regards,
Filippo

Hi @Filippo-GEG

I do understand your reactivity needs.

Can you share a draft of the UI you would like to have in your app and show the user flow and when this is time critical in user experience?

Sincerely,
François
