Hi,I am trying to write a bootloader that implements secure boot on STM32U545 or 585. Now I work on the SBSFU Example from ST on the discovery board b-u585i-iot02a as a starting point.Questions: Can I use a bootloader based on the SBSFU_Boot from STM...
I can't run the exe file on my pc, due to internal policies.Could someone upload the whole directory structure and files in github?
I'm using H753 which has hw crypto, and was hoping to improve the sbsfu execution time (e.g. time to validate FW header at start tup) by enabling hw crypto. However HAL_CRYP_MODULE_ENABLED doesn't do anything. I looked through the integration guide a...
Hello everyone,I'm experimenting PCROP activation on stm32h743 following this ST-tutorial: https://youtu.be/7Wr90XFA8_Q?si=tDpqUtMdin9Oyn-PThe activation works fine but i cannot disable PCROP using CubeProgrammer.I did a RDP1 to RDP0 regression with ...
Hello everyone,I am working with the STM32H7B3 and after enabling the secure user memory, i am not able to connect with the debugger anymore:For testing if secure user memory works, i put a "secure_function" in a section at the end of my flash, then ...
Hello everyone,i am trying to enable the secure user memory on the stm32h743 using the x-cube-sbsfu project and have the following problem:After activating the security bit, the value of the OPTSR_PRG flash register is not changing, so the security b...
I'm successfully implemented IAP for stm32h745. so I wish upgrade to sbsfu.Sbsfu has security firmware upgrade. When i implement for IAP, Firmware file was merged cm4, cm7 binary file using Srecord.If I merge files, won't the integrity of the firmwar...
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...
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 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...
