This is a driverless (no USB drivers needed, even on Windows) USB HID bootloader for STM32F10x and STM32F4xx devices.
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.
This repo is based on bootsector's stm32-hid-bootloader repository but is customized to follows the STM32duino ecosystem requirements. The source files (Bootloader and CLI) can be compiled on Windows, Linux or Mac
cli
folder contains the source code for creating the command line tool hid-flash tool.
This bootloader should't have any compiler restrictions, so it should work with
any GCC ARM toolchain version (latest is always recommended!). Just run 'make' on that folder.
D:\STM32_HID_bootloader\cli>make clean
Clears the previous generated files
D:\STM32_HID_bootloader\cli>make
Creates the hid-flash.exe file
bootloader
folder contains the source code for creating the hid_bootloader.bin file that is burned into the STM32F103 flash memory. Currently, only STM32F103 MCU is supported. Making the hid_bootloader.bin
STM32F10x
D:\STM32_HID_bootloader\bootloader_F1\bootloader>make clean
Clears the previous generated files
D:\STM32_HID_bootloader\bootloader_F1\bootloader>make
Creates the hid_bootloader.bin file
STM32F4xx
D:\STM32_HID_bootloader\bootloader_F4\bootloader>make clean
Clears the previous generated files
D:\STM32_HID_bootloader\bootloader_F4\bootloader>make
Creates the hid_bootloader.bin file
The binary file can be found in:
D:\STM32_HID_bootloader\bootloader_F4\bootloader\build\HID_Bootloader_F4.bin
