I do have the document UM2262 which describes the SBSFU expansion package, but it only gives a fairly brief explanation of the prepareimage tool.
Hello ST Community,I'm currently working on a project using the STM32WB55 MCU and am in the process of implementing Secure Boot and Secure Firmware Update (SBSFU) in my custom application. As part of this, I decided to test the existing 1_Image_SBSFU...
Hello,I am using STM32H750 and X-Cube-Crypto lib. I am working on a secure boot and want to calculate the app Hash value to check integrity. The library works fine for STM32L5 Mcu (Already tested) but not with STM32H750. I verified that I am using th...
Hi Team,I hope this email finds you well. I am reaching out to inquire about documentation similar to UM2262 but specific to the STM32H5 microcontroller.We are currently working on a project that involves firmware encryption, decryption, and update p...
Hi, I'm quite familiar with STM32 trustzone features. Also I know due to there's a random number generator it should be ANSSI capable. But I can't find anywhere a text "ANSSI". Have you as a ST already applied a ANSSI certificate for STM32U545 or any...
According to Wikipedia The MODBUS uses the CRC-16-ANSI also known as CRC-16-IBM. The normal hexadecimal algebraic polynomial being 8005 and reversed A001Initial value: 65,535.Example of frame in hexadecimal: 01 04 02 FF FF B8 80(CRC-16-ANSI calcul...
Hi All,I've got a question about the documentation and operation of the SBSFU partial image generation.The partial image feature of the image preparation tool is documented in the appendix of the getting started document here: https://www.st.com/reso...
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...
Hello,I am working on implementing secure firmware with OEMiRoT boot on the STM32H563. I have configured I2C1 and TIM1 as non-secure peripherals. While the TIM1 interrupt works as expected, I am encountering an issue where the I2C1 slave interrupt ha...
Hi @Jocelyn RICARD Greetingswe are trying to run TFM example (with secure and non secure project) taken from GPIO_Toggle_TZEN Example and adding SPI communication in the non secure project on our custom board mounted with STM32U585aii6q controller SP...
