OPP debug port / STM32 blue pill

[mrechte]

Hello,

I see that SWIO/SWCLK (debug port) pins are reallocated to GPIO (PA13, PA14), used on WING0 and WING2.

Apart from historical reason, is there a necessity to use those pins, I can see that PA11, PA12 are not used and could be used instead of PA13, PA14 ?

Thanks

PA11, PA12 are used by USB port.
