Literature
Target description
How to sign / encrypt a basic application loaded by BootRom Which OTPs are concerned by BootRom Authenticity and integrity checks How to get the BootRom traces How to set the device in closed-locked state
Introduction
Start by reading the Intro article.
Prerequisites
- Hardware
- STM32H7S discovery board: the STM32H7S devices have all the available security features, including the HW crypto accelerator (the HW cryptographic acceleration is not support for STM327R devices).
- Discovery MB1736- STM32H7S (need USBC cable)
- STM32H7S discovery board: the STM32H7S devices have all the available security features, including the HW crypto accelerator (the HW cryptographic acceleration is not support for STM327R devices).
- Required tools
- IAR : v9.40.1 + IAR patch to support STM32N6 (delivered with V0.5.0)
- STM32CubeN6 FW version 0.5.0 & patch version 0.5.1 & 0.5.2
- STM32CubeProgrammer version 0.0.2-N6-B03
- Tera Term / Putty or equivalent terminal emulator
- STM32Cube Firmware
- Download the STM32Cube_FW_N6 Cube firmware (advise is to place it close form the C: in order to avoid long windows paths).
- A directory STM32N6-DK is included in "STM32Cube_FW_N6\Projects" .
- Open the env.bat file
- 1- If the STM32CubeProgrammer has not been installed in the default folder:
- 1- If the STM32CubeProgrammer has not been installed in the default folder:
C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer, the customized installation path needs to be updated.
- 2- Update the COM port to be aligned with your COM port number.
- 2- Update the COM port to be aligned with your COM port number.
Use the Windows device manager to find out your COM port number, as shown in figure below:
- 3- Check that the OEMiRoT_Appli path is OK. The picture below shows the configuration path for the STM32CubeFW example but it is possible to select an other application that respects OEMiRoT template.
