Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
I have created my secure boot demo project on STM32H563ZI using the link below.https://wiki.st.com/stm32mcu/wiki/Security:How_to_start_with_STM32CubeMX_OEMiRoT_Boot_path_on_STM32H563During provisioning, the secure image is signed by the TPC (STM32Tru...
Our current product uses the STM32H533 microcontroller and password based Debug Authentication. We have a need to generate a large number of different DA passwords and corresponding OB Keys provisioning data. This is possible by creating our own tool...
OTP portion of FLASH is a valuable asset in some STM32 families and represents a convenient place to store things like security keys. For this, it is desirable - and, as it's part of FLASH, also quite logically expected - that setting read-out protec...
Hello everyone,I'm trying to disable the TrustZone (TZEN bit) on an STM32L562E-DK development board to leave it in a completely clean state (without protections) so I can use it as a standard MCU. However, I'm encountering errors when trying to modif...
Hello everyone,I am working on a custom board based on the STM32U575RGT6 (1MB Flash). I am encountering a hard fault (SecureFault) during the initialization of the Non-Secure application after integrating the SBSFU.Context:Hardware: Custom board with...
I have been looking at the CRA Q&A and was wondering what you you are meaning with the reporting of security incidents 2026-12-11. Do you mean the reporting according to article 14 that enters into force 2026-09-11?
Hi, I'm starting to play with the SBSFU examples provided by ST. I'm trying to build the SBSFU (mcuboot based) example for the STM32L5 which can be found in the STM32SecuWS provided here . I'm stuck trying to build the TFM_SBSFU_boot (partial console...
Hi Community,I am porting STM32Cube_FW_U5_V1.8.0\Projects\B-U585I-IOT02A\Applications\SBSFU example to be used with USB port for firmware upgrade instead of Uart. I use B-U585I-IOT02A board with U585. Because of some requirements I need to use bare m...
Hello ST, I am working with STM32WBA52 and I am no longer able to connect to the device using STM32CubeProgrammer. When trying to connect, I got the following error: The interface firmware FAILED to reset/halt the target MCU A fail.txt file is also g...
