1. Using the example

To ease the example generation and loading, a script is provided in the STM32Cube package. The script called “provisioning” is available in \Projects\NUCLEO-U083RC\ROT_Provisioning\OEMiSB.
The script execution is following steps:

  • 1. Configuration management'
    • RDP selection
      • 0: In this case the development mode is enabled
      • 1: Production mode is enabled, and debug is possible
      • 2: Production mode is enabled, and debug is not possible
    • Data size selection
  • 2. Image generation
    • Compilation of the application and generating binary file.
    • Editing boot header files automatically.
    • Computing application HASH and generating hash area binary.
    • Compilation of the boot.
  • 3. Provisioning
    • Remove old protections and initialize option bytes.
    • Perform mass erase.
    • Download application, boot and hash.
    • Hardening by enabling HDP and WRP.

The script is useful to automate hash generation, which would have to be manually imported into the binary on each build.
