Thread Viewer does not show threads

[User_PP]

Hey,

I encountered a problem with the thread viewer, where the corresponding window is empty when I'm in a debug session. Inside the build configuration I used "Optimize for debugging (-Og)"

I tested this in the "threads" example. I used the nrf connect SDK v 2.9.0 and Toolchain v2.9.0 with an actinius icarus (nrf 9160) board and VS Code V 1.97.2 on windows 10.

[JONATHAN LL]

Hi,

Thanks for reporting. 

Can you test with the Ozone debugger to see if it works there?

Regards,
Jonathan

[User_PP]

Hey Jonathan, thanks for your reply. I installed the Ozone debugger and got it to attach to the process. Where do I go from here to view the running threads and test this?

[User_PP]

Nevermind, I found the "Debug with Ozone" button. There it works, yes 

[JONATHAN LL]

Good to know that it works, there is clearly a issue here with the window that should be displaying the threads. 

I dont know the cause here but here are a few things that you can try if you want to continue investigation on the issue. 


What language is the default language on your computer? This does sound like a odd question but there seems to be at least one other case where someone had it fixed buy making sure the English US language package was available on the windows machine. 

There is also the possibility that some parts are not checked, here in the thread setup https://github.com/nrfconnect/sdk-zephyr/blob/v3.5.99-ncs1-1/subsys/debug/thread_info.c#L42 if this part is missing the window appears to be blank as well. 

You can try and update VS code, ore maybe downgrade VS code as well to see if this solves the issue, 

You can click here on the cog and select install specific version and select 2024.7.13 to see if that solves it. 


If you dont want to digg any more in to it then that is perfectly fine and you can use the Ozone workaround. 

Regards,
Jonathan

Hey Jonathan, 

thank you for your response. I tried to look into your suggestions, but so far none of those seemed to have an effect.

1) I checked the system settings for the selected language, and it is set to English US already.

2) Here I'm not entirely sure what I should do specifically. I tried multiple things:

* I added the following line to the beginning of my program:

__attribute__((used, section(".dbg_thread_info")))

* When looking at the CMakeLists file in the parent folder, it seems this .c file is included when "CONFIG_DEBUG_THREAD_INFO" is defined, so I added "CONFIG_DEBUG_THREAD_INFO=y"  to my prj.conf file

Was there anything else you had in mind for me to do with this suggestion?

3) I installed the version you specified, but I encountered a different problem, where the extension window does not show content at all and is loading. I waited for 5 minutes and once I updated to the newest version, it immediately showed its contents again

So I unfortunately was not able to test whether it works in the version you mentioned
