 Hello and welcome to this presentation which provides references to documentation and URLs related to the implementation of TFM in the STM32U5. ST has released several documents that describe the implementation of TFM in the STM32U5. The application note 5156 presents the basics of security in STM32 microcontrollers. The application note 4995 supports the secure firmware install feature available on the STM32U5. The user manual number 2851 describes how to get started with the STM32U5 TFM application delivered as part of the STM32U5 MCU package. The user manual number 2852 describes how to prepare STM32U5 microcontrollers to make a secure system solution compliant with a CSIP profile for PSL level 3 using the STM32QFWU585 Security Certification V1.0.0 software package included in the STM32U5 MCU package. The BU585 IIoT02A board integrating the STM32U585 AI microcontroller is used as the hardware vehicle to implement and test a non-secure application using secure services but it doesn't bring any additional security mechanism. STM32QU5 TFM application and SBSFU application examples are provided for the BU585 IIoT02A board. The TFM-based application example consists of four main software components which can be configured by integrators according to their needs. TFM-SBSFU boot, secure boot and secure firmware update application TFM loader, application loader application based on Ymodem protocol over USART TFM-Apply secure, secure application providing secure services to the non-secure user application at runtime and TFM-Apply non-secure, non-secure user application. The SBSFU application is minimal with only the secure boot and secure firmware update services of the TFM. More general documentation can also be useful to gain knowledge on security standards such as the TFM user guide for V1.0 in all releases, the PAS developer APIs. Thank you for attending this presentation. You can now refer to the other presentations that detail how TFM works. TFM flash memory footprint and TFM offer in STM32U5.
