I've been looking at netduino 2 schematics and saw these pins were not used of STM32F205RFT6.
PA4 PA5 PA7 PA8 Reserved ? PB0 PB1 PB4 PC8 PC9 Reserved ? PC10 PC12 PC15 Reserved ? PD2
Can I know the reason ? Is it because of making compatible to arduino ?
and why multiple pins for bootloader ?
PB11 and PC14, PC11, PB5
