Dear Support Team,I am currently working on a project involving the STM32H5 microcontroller and I am in need of a document that details the process of firmware encryption, decryption, and update for this device. I have previously used the UM2262 docu...
Hello,I have NUCLEO-U575ZI-Q board and I have followed the steps to generate an SFI file from the video "STM32Trust Video Series: X-Cube-SFI Part 3-Out-of-the-box". I managed to generate the SFI file correctly but when I tried to install the firmware...
Hello folks,i am exploring the x-cube-sbsfu project and have 2 questions:Question 1:why is the SeCoreBin built separately and then later integrated to SBSFU? What is the motivation behind that?I was thinking about putting SeCoreBin and SBSFU in one p...
I've implemented on my own board (MCU STM32WLE5CCU6) bootloader SBSFU from example 'STM32Cube_FW_WL_V1.3.0\NUCLEO-WL55JC\BFU_1_Slot'. Everything works ok.In my own aplication i must change download channel from usart to by radio FSK. Because of handl...
Hello,I am working on a large project on a custom board based on STM32 L5 series. I've already set up, implemented, and tested my code using STM32CubeIDE. Now, I'm trying to integrate the project into SBSFU. For that reason, I am using the SBSFU exam...
Hi,I'm looking into introducing STM32 Secure Boot and Secure Firmware Update based on X-CUBE-SBSFU library on my project with app based on CubeMX v6.11.1 (BSP1.28.0).I noted in CubeMX the MPU option is still not available for FreeRTOS - which is used...
Hi, I'm trying to build TFM example applications from the B-U585I-IOT02A directory to work on Nucleo-U545RE board. THe documentation says it's possible. I have updated the project settings, but I'm getting errors from the STSAFE library: C:/Work/OldC...
Hello,I've implemented secure bootloader on STM32H753ZI using SBSFU examples and it's working very well. To secure the board I use WRP + RDP Level 1 + Secure Memory Area for bootloader. I would like to have option to recover from this state and be ab...
Hello,I need to implement AES-CBC 192 bits on micro STM32U5 serie, but hardware only supports 128 or 256 bits If i use XCUBE-SAFEA1, ST_Cryptolib is not available for U5 serie.How can i fix this issue?
Hello,We are developing a product based on a STM32WB5MMG. We have configured the SBSFU with OTA (Asymmetric with AES encryption scheme). Everything is working great and I have only one question that came to my mind during the last commit...The CBC ke...
