No wear and tear on flash if you debug in RAM. And slightly quicker download.

But less RAM for variables.

And remember to remap your interrupt vectors into RAM, and set PC to the correct position before starting.

Keil have examples where you switch target to either build a flash version or a RAM version of their examples.

Might be easier to set break points and/or support more breakpoints...?

Yeah, I think you're referring to debug and release.
So my question is, What is the difference of debug (RAM) and release (FLASH)?What happen to the code execution during debugging either you select one of these target?
