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...
