Hi,

Apologies for the delay. I was able to replicate it here. I am discussing this with experts in order to find a solution and will keep you updated.

devzone.nordicsemi.com/.../video.zip

Please try this one, it should work better if you are using Windows.

To let you know, the other video could be downloaded and watched via VLC application on any OS.

I am using SDK 2.6.1 with VS Code on Mac.

The board I am using is:

PCA10090
1.1.3

Hi,

I a unable to view the video that you attached. Would it be possible to zip the view and attach the file?

I nevertheless tried to reproduce the issue on my DK here and was not successful. It would be great if you could attach the video once again so that I can see what's happening at your end.

Could you also tell me which SDK version you are working with? And what is your DK revision?

I'm sorry but something is wrong with debugging using the dev kit nRF9160 DK.

This should be straightforward.

Below a video, please try to reproduce the issue, I'm not doing anything fancy, just using "fund_less2_exer1_solution" sample code and trying to put a breakpoint in the while loop.

CONFIG_NO_OPTIMIZATIONS=y

CONFIG_DEBUG_OPTIMIZATIONS=y

Please check the following video and let me know:

Hi,

The breakpoint issue you are facing is because of the optimizations that take place. This changes the machine code so that it does not exactly map the C code, so it makes debugging harder. So the only way is to disable all optimizations when debugging. Please take a look at this ticket.

Priyanka

Hello

Still not able to put breakpoints where I want and also I get the notification "The selected build configuration does not have debugging options enabled" even though I enable either CONFIG_NO_OPTIMIZATIONS or CONFIG_DEBUG_OPTIMIZATIONS in the prj.conf file.

Hi,

Could you tr building with project default ? Does this help?

No worries 🙂

So here I select any since CONFIG_NO_OPTIMIZATIONS is not possible in the drop down list:

Then in prj.conf I do force CONFIG_NO_OPTIMIZATIONS=y and CONFIG_DEBUG_OPTIMIZATIONS=n:

Then in "Output files" folder I have .config file with:

Somehow I still can't add a breakpoint anywhere I want.

Is .config file the final state or is it overridden by prj.conf?

Hi,

Apologies for the delayed response.

It looks like selecting both

CONFIG_DEBUG_OPTIMIZATIONS and

CONFIG_NO_OPTIMIZATIONS

can cause a conflict. So generally you select any one depending on your needs. So please try choosing CONFIG_NO_OPTIMIZATIONS if you want to ensure absolutely no optimization, which makes debugging straightforward and choose CONFIG_DEBUG_OPTIMIZATIONS if you still want some optimizations but in a way that doesn't interfere too much with debugging.

Please try this and let me know how it goes.

Priyanka

I've modified the prj.conf file as follows:

However it seems that CONFIG_NO_OPTIMIZATIONS is overridden to `n` instead of 'y'.

By the way, I'm using a Mac but it shouldn't make a difference.

Hi,

Did you enable the following on your prj.conf ?

CONFIG_DEBUG=y

CONFIG_DEBUG_OPTIMIZATIONS=y

CONFIG_NO_OPTIMIZATIONS=y
