This demo is targeted towards the Nucleo-H563ZI board, with 2048 kB internal Flash EEPROM and 640 kB internal RAM.
To compile the demo programs you can use the STM32CubeIDE development environment. Note that STM32CubeIDE is cross-platform. The information outlined on this page applies to both Microsoft Windows and Linux users.
To program the bootloader into the internal flash, the on-board ST-Link debugger interface was used. Firmware updates via the serial communication port are preconfigured to use the virtual COM-port offered by the ST-Link. This means that no additional hardware is needed, besides a standard USB-C cable.
Two demo projects are included in the OpenBLT bootloader package. One for the bootloader itself and one for the demo user program. This user program is configured such that it can be programmed, into the internal flash memory of the microcontroller, during a firmware update with the bootloader.
The first step in getting the the bootloader up-and-running, is the creation of the Eclipse workspace in STM32CubeIDE. After starting STM32CubeIDE, you are prompted to open a workspace. It is easiest to create a new one in the following directory: .\Target\Demo\ARMCM33_STM32H5_Nucleo_H563ZI_CubeIDE\
To import the demo programs into the workspace, select File → Import from the program menu. Then select General → Existing Projects into Workspace. On the next screen you select the following directory as the root directory: .\Target\Demo\ARMCM33_STM32H5_Nucleo_H563ZI_CubeIDE\. Eclipse will automatically find the Boot and Prog projects and select them:
Click the Finish button to complete the project import operation.
Before the bootloader can be used, it needs to be built and programmed into the STM32H563ZI's internal flash memory. The steps in this section only need to be done once.
The bootloader program is now ready to be programmed into the internal flash memory of the STM32H563ZI microcontroller. Make sure the Nucleo-H563ZI board is connected to your PC via a USB cable. Next, select Run → Debug from the menu to flash the bootloader program. This will launch the Debug perspective in Eclipse. Once done, you can start the bootloader program by selecting Run → Resume from the menu.
Alternatively, you can use your favorite programmer to flash the bootloader using one of the following files, depending on what file type your programmer supports:
The output file is
