Fail to debug E83-2G4M03S with nRF5340

Hello!

I bought dev board with this module and plan to use it in my product. 

I bought a development board with this module and plan to use it in my product.

While I have some experience working with previous nRF products, it's been a while, and I'm a bit confused with this one.

I tried setting up a workspace in VS Code. The build, flash, and debug processes complete successfully. However, when I try to debug any example or my own basic programs, breakpoints end up in strange locations, and I have no control over execution. After I press "Step Over" or any other action, the debugger freezes, and only "Restart" brings the program back to the same point.

When I created the build, I selected the "optimize for debugging" level. I also tried different example projects and even created a simple main() { while (1); } program, but the behavior remains the same.

I have no clue what is going on.

This kind of behavior is often related to optimization settings or mismatched debug configurations, even when “optimize for debugging” is selected. You might want to double-check the toolchain version, debug interface settings, and ensure symbols are generated correctly.

Thank you.
It’s been quite a while since I posted this question, but I eventually figured it out. It turned out to be something odd—basically, switching it off and on again. After some tinkering, it worked.

Doing pristine build is also very important. Just in case if anyone also get this kind of trouble
