Hello! Sorry about the delay.

[quote user="MayurKumar"]program execution didn't halt at breakpoints[/quote]

I see, that is odd. And you do manage to set the breakpoints? Note that not every line gives you that option.

What about at line 90 on loader.c? Place a breakpoint, then go to Debug --> Reset --> Reset & Run.

[quote user="MayurKumar"]Is there any settings to be enable for nRF9160DK board?[/quote]

Nothing you require for this to work, but speaking of which I believe CONFIG_DEBUG_OPTIMIZATIONS could be helpful.

Best regards,

Elfving

Hi,

I am able to debug my custom board using ozone debug as per your suggestion.

My issue is that mcuboot is unable to read/swap the image. So i want to debug loader.c file on nRF9160 DK board. When i do same process for DK board i unable to debug it (program execution didn't halt at breakpoints)?

Is there any settings to be enable for nRF9160DK board?

Hey Mayur!

Yes, this is possible. This is what you need to do:

- Program the sample to the chip

- Start an Ozone-session, and when you choose an elf file, then choose <sample>/<build folder>/mcuboot/zephyr/zephyr.elf.

- Then you drag the file /bootloader/mcuboot/boot/bootutil/src/loader.c into the Ozone window.

- Then choose debug --> start debug session --> Attach to running program

- Then set a breakpoint in loader.c and press Debug --> reset

This should work.

Best regards,

Elfving

Hey Mayurkumar!

I see you have another case that strictly isn't related to this, but still has the same title. Please keep the support tickets separate by giving them different and descriptive titles.

When it comes to your issue though, it might be that the thread isn't running on the files you mentioned. Can you tell me more about what configurations you added?

Best regards,

Elfving
