Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Hello, I am trying to use SAES with a wrapped key to decrypt firmware updates on an stm32u5g9vjtxq. I am not sure how I should be changing the InitVect in CRYP_AES_CBC mode after hcryp is already initialized with HAL_CRYP_Init. To elaborate on what ...
Hello!I have a custom PCB using the STM32U5A9 microcontroller.I've been developing my code using Cube IDE with CubeMX generated software including TouchGFX.I need to implement secure boot and OTA. I am following the SBSFU example for the B-U585I-IOT0...
Hello,I would like clarification on the behaviour of STM32U3 devices when Readout Protection (RDP) Level 1 is enabled.Configuration:TrustZone: DisabledDebug interface: SWD/JTAGQuestions:With RDP Level 1, is Flash completely unreadable by any third-pa...
Hi, I am trying to implement DA on an stm32H563, I have created the .obk file, and was selected in the Stm32Programmer. I have changed the product_state to provisioning and I got the message "Do you want to use the default?"I clicked YES and I got th...
I am currently working with the STSAFE-A110 and I have noticed a significant lack of documentation for those who need to implement or understand the driver logic.For instance, when generating ECC asymmetric key pairs, the official datasheet mentions ...
I'm working on a project which is being ported over to be TrustZone aware, part of this project makes use of an OCTOSPI configured in memory mapped mode for file access. Base settings come from the IOC however the memory mapping is executed in source...
Hello,After creating a new project based on the FreeRTOS_Queues_ThreadFlags_TrustZone example from MX and generating code, there is a compile error:[build] C:/Users/tuoma/AppData/Local/stm32cube/bundles/gnu-tools-for-stm32/13.3.1+st.9/bin/../lib/gcc/...
I have a working program on my own board using a STM32G081KBU6. Debug using SWD and programming a release version works fine. As long as RDP remains at Level 0, I'm able to debug, erase and reprogram updates to the board.Usually for other ST MCU's th...
Hello, I'm posting a new message because the previous one was not answered with successful connection. The problem is that when MCU is populated on my board with Read-Our Protection enabled, it is not possible to connect STM32CubeProgrammer v.2.21.0 ...
Hello,I'm looking for some clarification over how the PCROP area can be used. The user manual for STM32L471 states that code in this area can be executed but that data at flash in this area cannot be read. Does this mean if I put a decryption algo...
