[mcykin]

hi,i bought a STM32F103RCT6 Developed board.



this board don't have any led or board-key except NRST,

so,which kind of bootloader should i use?
can i use generic_boot20_pc13.bin(as same as blue piils) to download?

and also,when i download the bootloader,i'll change boot0 to pin1,use Demonstrator GUI download generic_boot20_pc13.bin,and reboot,is this right?

thanks!

you need a
- st-link v2

or a
- usb-uart dongle that does 3.3v uart

- set boot0
- toggle reset
- flash away

or alternatively get a stm32f401 or stm32f4xx board with usb
stm32f4xx chips has the DFU boot loader built in

- set boot0 (press both boot0 and reset)
- toggle reset (release reset, hold boot0, release boot0 1 s later)
- flash away

with the tools, follow the 'getting started' guide in the wiki

Yes, you need to pull up BOOT0 pin, reset board, use a usb-uart adapter (f103 do not have USB bootloader), flash bootloader.
You can use Demonstrator GUI or STM32QubeProgrammer.
