Debugging Problems'ssss

By chance I got the Debugging working with Jlink+OCD(Vmicro) on the Target Generic STM32F1 series, Bluepill 103C (see image) for the Blink example. It works despite an exception, see second image.

How to fix that?

There shosuldn't be any "chance" if you use the docs Smiley

That suggests the optimization setting is preventing you from delving deep into the core.

Had watched hundreds of posts.

I tried all of the 16 combinations of optimization methods.

The STM32 Core has an additional Optimization set of settings (on board menu), which to debug reliably needs to be set to "Debug -Og" (shown as "Smallest -Os(default)" in the above screenshot).

More Information about what these Optimization flags mean and behaviour, is available on the GDB Site:
https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html
