I have legacy SBSFU based system running on an stm32f429 for a few years now, based on the STM32F413ZHT6 demo code that was present in the package. I am now interesting to using the KMS feature of SBSFU but after reading um2622 /seeing https://www.yo...
I am trying to integrate a very simple TouchGFX Application into the SBSFU (I only really need SB right now) application, on STM32U5A9J-DKI've switched out the Nonsecure application for mine, I've modified flash_layout to do primary only, no external...
I've been watching the MOOC - Security series and had some questions. There is a link in the info block to a forum for any questions, but the link no longer works. https://www.youtube.com/watch?v=g7ykhnmh7sAIs this the right place?I got to the end ...
I am working with the STM32U585RIT6 and need to implement a secure firmware update. In my application code, I don’t want to handle flash management or low-level update logic. I only want to generate a secure binary file and perform the update.I revie...
Hi all,I was doing a firmware update from my raspberrypi to my MCU through I2C, and I facing this write protection issue.On initial flash with swd, I was flashing bootloader + main app to their required locations with their meta data like CRC program...
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 ...
