nRF Connect SDK Intermediate Lesson 1 Exercise 1 Debugging Issues

[TomSansome]

Hi

This is my first time using nRF connect and Visual studio but I have been following through first the Fundamentals course on the Dev Academy using the nRF52840 DK with no issues.

However in exercise 1 of lesson 1 of the Intermediate course, when attempting to debug i do not end up in "main" function but in the file ".../zephyr/arch/arm/core/cortex_m/reset.S". I also do not have any of the functions showing in the call stack or any threads in the thread view of the NRF Debug terminal.

The code appears to run correctly if i stop debugging and i get the LEDs toggling and the terminal outputs as expected and i get the same behavior using the solution code so i assume it is something to do with my setup rather than the code itself.

I am connected to the nRF52840 DK directly via USB.

I would be grateful for an suggestions on how to go about resolving this.

Hello,

Does it start in reset.S? Have you tried setting a breakpoint somewhere near the start of your main() function, and then hit the "play" button near the top of the VS Code window?

Does it jump into main() then?

Best regards,

Hi Edvin,

Thanks for getting back to me.

Yes it starts in reset.S, if i set a break point in main() and then continue it stops at the break point in main() but I don't get anything in the Thread Viewer and the call stack only contains main().  If i add a break point at the end of main() and continue to it then the tread viewer is populated but greyed out (cannot interact with anything unlike the description in exercise 1) and the call stack still only contains main(). Is this how it is supposed to function?

Best regards,

Tom

Hello Tom,

Can you please share som screenshots showing what you mean is missing/wrong, and point to the figures/parts of the DevAcademy where you mean the behavior differs?

Best regards,

Edvin

Hi Edvin,

This is the example from the lesson in the DevAcademy when you start the debug session:

and this is what i see (when i use a breakpoint in main()):

As you can see my call stack on the left only has main() and the thread viewer is empty. Not sure why but today i cannot get the thread viewer to populate no matter where i add the breakpoint.

Cheers,

Tom

Make sure that you have added "CONFIG_DEBUG_THREAD_INFO=y" to your prj.conf, and then delete your build folder, and rebuild the application before trying once more. If it still doesn't show up, try to hit the restart button
