I'm trying to create ECDSA keys on a STM32WL55 using the X-Cube/HAL Crypto library. I can generate NIST keys no problem, however when I try using the Brainpool curves, it mostly returns the following error: CMOX_ECC_ERR_WRONG_RANDOM ((cmox_ecc_retval...
Hello,I have created my own program using TrustZone and I want to add the SBSFU_BOOT project to it. How can I do this?
Hello, I am writing code for changing the RDP Level, but I am facing a hard fault trigger in the code:this is the line after unlocking the FLASH_CR_LOCK, and FLASH_CR_OPTLOCK. After unlocking able to change the RDP level to 1 or 2 but as soon the deb...
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...
