I want to use the bootloader via 

USART2 (PD5/PD6) - except my USART2 is mapped onto PA3/PA2

Is there any way around this? #bootloader #stm32

The ROMs basically support fixed and defined level of functionality, build to that.

You could also use test points not utilized in the final design, ie pins could driver board LEDs, but USART1 or USART3 in test fixturing.
