Build bin

git clone https://github.com/rogerclarkmelbourne/STM32duino-bootloader

cd STM32duino-bootloader

make generic-pc13

this will produce bootloader_only_binaries/generic_boot20_pc13.bin

Convert bootloader to hex format

using srec_cat to convert
windows: http://srecord.sourceforge.net/
linux: sudo apt install srecord

srec_cat bootloader_only_binaries/generic_boot20_pc13.bin -Binary -offset 0x08000000 -output bootloader_only_binaries/generic_boot20_pc13.hex -Intel

Next is to use stm32Cube to flash the bootloader

• Download the stm32cube programmer
  stm32cube programmer

• Put 1 ON in the back of keyboard

• Connect keyboard with a usb-serial convert by fpc, in order of IO MAP

• Click connect on STM32cube programmer

• flash it

Flash Arudino

Arduino IDE

• add stm32duino pacakage index in Preference panel : http://dan.drown.org/stm32duino/package_STM32duino_index.json as Additional Boards Manager URLs: and install STM32F1xx/GD32F1xx boards

• verbose all outputs:
  

• Select upload method ,board type is **Generic STM32F103R series **
  

• Set cpu mhz to 48Mhz
  

• Put 1 OFF in the back of keyboard

• User arduino IDE to open devterm_keyboard.ino

• flash it

CN version
