The free usage of library is limited to 20 boot cycles It is meant for testing and demonstration only. It can be customized to use on any of STM32 controllers. The bootloader and application have been tested on the below controllers with 1Mb flash memory. This file can be used for Serial/OTA firmware updates. The final encrypted application binary will be generated in Debug folder as projectName_release.bin.
The final application binary file will be encrypted using executable script(BS_ENCRYPT.exe). Include the precompiled object file to the project. Include the utils folder containing the library header files to the project.
Restart your PC and you should be greeted with the Grub Menu. After you run the above command, it will change the bootloader back to Grub. Type cmd and press Ctrl + Shift + Enter to open an elevated Command Prompt. MEMORYĬCMRAM (xrw) : ORIGIN = 0x10000000, LENGTH = 64K Press the Windows + R keys to open the Run utility. Memory Map and linker settings TypeĪpplication resides at 0x08010000 and same has to be configured in the linker settings as shown below. It uses the pre-compiled library object which will be linked with user application. Use the f407_led_demo project to build the custom application. After successful update, notice the change in firmware version and LED pattern.In the previous section we have flashed bootloader and application v200, this time only application needs to be flashed.įlash app.Notice the version number and LED pattern.
After successful update of the firmware, device will print the versions numbers.CLI will takes care of flashing the bootloader and application one after the other.Flash both bootloader and application using the flash all command as shown below.įlash all.flash app This will only flash the application from the specified path.\binaries\bootloader.bin and application from the specified path. flash all This will flash the bootloader from.CLI also allows to flash the custom application by providing the absolute path to the below commands. The required application binary file path has to be provided for flashing the application. For testing, two application binaries are available in.
For flashing the bootloader, user need not provide the path. \binaries folder and same is hardcoded in the CLI tool.
Download and install stlink_setup.exe, and add the path to environment variablesĬ:\Program Files (x86)\STMicroelectronics\STM32 ST-LINK Utility\ST-LINK Utilityīootloader and application use UART2(PA2, PA3) for firmware update and printing the device logs.
