Hello,I am developing an application on STM32H7 MCU which uses SBSFU bootloader for secure firmware updates. I am trying to combine the SFB update package with some additional data in a single binary file that is sent for the firmware. To make this w...
Hi, I've created a project in STM32CubeIDE 1.14.1 for the Discovery board B-U585I-IOT02A with TrustZone enabled. Unfortunately, I'm unable to select any of the TIM timers as the SYS_NS and SYS time source. They are disabled with the following message...
Hi,I have a STM32HSM-V2AE and I tried to follow de "SFI Step-by-step on STM32 boards". In the part of "HSM programming" I connect the STM32HSM-V2AE to the computer with the smart card reader HID OMNIKEY 3121 but I have the following error:Error: HSM ...
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...
