# STM32F103C8 "Blue Pill" # NOTE: # There is a fair bit of confusion about whether the "Blue Pill" has 128kB or 64kB flash size. # The most likely cause is that there exist a -C8 and a -CB variant of the STM32F103, where # the C8 has 64kB, the CB has 128kB as per specification. "Blue Pill" boards are manufactured # by a lot of different vendors, some may actually use the CB variant but from a cursory look # it very hard to tell them apart ("C8" and "CB" look very similar). Nevertheless, people have # tried using the full 128kB of flash on the C8 and found it to be working. Hence this board file # overrides the internal size detection. Be aware though that you may be using you particular # board outside of its specification. If in doubt, comment the following line. set FLASH_SIZE 0x20000 source [find target/stm32f1x.cfg]
