5.2 STM32WBA5 series
5.2.1 Software build
The following steps describe the operation to build a secure boot example code with its demonstration application
and its loader application based on the STM32CubeWBA MCU Package for the STM32WBA series under
®
Windows . For more details on STM32CubeIDE, refer to [UM2609].
• Install the package in a folder.
• Open the folder .\Projects\NUCLEO-WBA52CG\Applications\SBSFU\SBSFU_Boot\STM32CubeID
E
• Double-click on the .project file to open automatically STM32CubeIDE to import and set up the secure
boot example
• Open the folder .\Projects\NUCLEO-WBA52CG\Applications\SBSFU\SBSFU_Appli\STM32CubeI
DE
• Double-click on the .project file to import automatically and set up the demonstration application in
STM32CubeIDE
• Open the folder .\Projects\NUCLEO-WBA52CG\Applications\SBSFU\SBSFU_Loader\STM32Cube
IDE
• Double-click on the .project file to import automatically and set up the loader application in
STM32CubeIDE
• In SBSFU_Boot project:
– Disable the TFM_DEV_MODE compilation switch if the building is for the production version. The
RDP level is configured to 2.
– Keep TFM_DEV_MODE enabled, if the building is for a development version. The RDP level is
configured to 1.
• Select Menu->Project->Build All
• Wait for the expected message: Build Finished. 0 errors, 0 warnings
5.2.2 Software programming
• Execute regression.sh located in .\Projects\NUCLEO-WBA52CG\Applications\SBSFU\SBSFU_
Boot\STM32CubeIDE to initialize the device.
• Execute SBSFU_UPDATE.sh located in .\Projects\NUCLEO-WBA52CG\Applications\SBSFU\SBSF
U_Boot\STM32CubeIDE to program the binaries into the user flash memory.
5.2.3 Static security protection programming
• Execute hardening.sh located in .\Projects\NUCLEO-WBA52CG\Applications\SBSFU\SBSFU_B
oot\STM32CubeIDE to configure all security option bytes.
• Connect Tera Term console on serial port STMicroelectronics STLink Virtual COM Port configured at
115200 bauds, one start bit, one stop bit, no parity.
• Reset the platform.
• Verify that the application is alive with the message:
