Hardware and Software Debug
Can somebody explain what is the hardware and software breakpoint ?
When I add a breakpoint in STM32CubeIDE, what is the type of this breakpoint ?
What is the difference between these two?

Hardware is where the FPB/DWT are trapping based on address access within the memory space.
Software would be where you're physically placing a BKPT instruction into the execution path.
Typically you're using the former, as it doesn't change your code.
