Some time ago I tried your STM-STUDIO: I found it very rough and can only be used for laboratory debugging.
Why don't you plan to build a more flexible debugger that can then be used by the end customer to view internal data or change parameters?
If you STM engineers have no idea what I'm talking about, I suggest you take a look at what NXP's FreeMaster does. This is the link.
