Problems with "Enable debug options"

[Lars M]

Hi,

I am facing a problem with the selection "Enable debug options" when creating a build configuration. I use nRF connect SDK 1.9.1 with VSCode. I create an application from sample aws_iot. Then I make two different build configurations, one with "Enable debug options" checked, and one with the option unchecked. The one that has debug option enabled is not possible to debug (it may work once, but all other debug sessions do not work). But the one that doesn't have the option enabled works fine to debug.

How come there is a difference?

What does "Enable debug options" provide?

Best regards,
Lars

Hi,

I have replicated the scenario you described myself using aws_iot sample with VS Code and NCS v1.9.1. I did not observe any issue, no matter if "Enable debug options" was checked or unchecked, .

Best regards,

Hi Dejan,

Strange. I have staerted over, and the first time I debug the build configuration that has "Enable debug options" checked, it works fine. But all other debug sessions don't. I have attached three files with the printouts from "Debug console". One file is how it looks in the build configuration that doesn't have "Enable debug options" checked. The other two has the option checked. The one where debugging is working is the first debug session, the other one is how it looks for all other debug sessions. Is it possible to find any interesting information from this?

Has any other of your team tested to see if you can repeat this?

What does "Enable debug options" provide?

Best regards,
Lars

Hi,

As can be seen in debugging application, ENABLE_DEBUG_OPTIONS sets the following in the prj.conf
CONFIG_DEBUG_OPTIMIZATIONS=y
CONFIG_DEBUG_THREAD_INFO=y

Best regards,
Dejan
