If you have SWD, there's no reason to use serial bootloader, as you
can not only flash but also fully debug (stepping, breakpoints,
watchpoints) the target firmware. I recommend routing out the reset
line to the SWD connector as that will allow the debugger to access
the target no matter what.

Good luck :)
