Segger EMBEDDED STUDIO debugger breaks at random lines

[Learner]

Hello

I am running this version of SES

SEGGER Embedded Studio for ARM

Release 5.34a  Build 2021011401.44914

Nordic Edition

Windows x64

When I run my program in Segger it keeps stopping at these two particular lines. I do not understand why it is breaking because there are no breakpoints set. I deleted all of them.

It seems as if there are two 'hidden' breakpoints at these two lines. The Breakpoints window shows none.

Can someone please help?

Kind regards

Mohamed

Thank you Karl,

I don't have access to an nRF52840DK.

Will the example run on nRF52833DK?

Kind regards

Yes, you should be able to run it just fine on a nRF52833 DK, just change the build target in the Open NCS SDK project prompt. Remember to select the Clean build directory option before opening.
It might be that the breakpoint is not already there for the nRF52833 DK build, but then you can add it yourself following my prior instructions. Just set the expression to be tester_value == 5 or similar, you should also use set it as a hardware breakpoint.
Let me know if you encounter any issues with it.

Best regards,
Karl

Thank you Karl.

You will need to make sure that the variable is a global one, so they have a fixed address instead of being on the stack.

So, are you saying Data breakpoints work only on global variables?

Kind regards

No, but for testing purposes you should make them global.
For the general case you will need the variable to have a fixed address in memory (which global variables do) so that it can be watched.
