 It doesn't use ST libraries since they are bloated and buggy. Only CMSIS and
 some required system files and macros have been used from ST provided SDK.
 
-This allowed for a very small bootloader ~~4 KB~~ **2 KB** on STM32F10x devices. On STM32F4xx devices there is no point to make the bootloader much smaller than 16 KB because the first flash page is already 16 KB.
