Hello ST team,We are working with the STM32WL5MOC6HTR module for a LoRaWAN end-device design.We understand that the STM32WL5MOC6HS variant includes an STSAFE-A110 secure element, but our custom module (MOC6HTR) does not include STSAFE.Our question is...
Hello! I want to implement secure boot / secure firmware install on my STM32u5A9 custom board. I am starting by trying to modify the SBSFU example code from B-U585I-IOT02A example project to run on my board. I followed the instructions in the README ...
We have an application running on an STM32WB55M. This user application makes use of standby mode, and the device is able to exit it when the configured pin changes state.However, once the SBSFU is integrated with the BLE_ota application, the user app...
Hello,STSELib development is under progressToday (version 1.1.4), STSELib uses some services from STM32_Cryptographic library instead of interfacing STSAFE-A120 component (for example HKDF)Is there any development planning for STSELib giving availabi...
hello, I'm run a STM32H573DK in OEMiROT example.but following errors occured.[INF] TAMPER Activated[INF] BANK 1 secure flash [0, 15] : OB [0, 14][ERR] Unexpected value for secure flash protection so, I find why occurred this error. In the ob_flash_p...
Hello @Jocelyn RICARD ,I’m integrating SBSFU v2.7.0 on an STM32WB55 to enable secure OTA firmware updates. I’m hitting a problem where the runtime hash verification fails: the hash computed by SBSFU at boot does not match the hash in the image header...
Hello everyone,I am working with the STM32H7B3-DK and evaluating the SBSFU package with a dual image slot configuration using SECBOOT_ECCDSA_WITH_AES128_CBC_SHA256. I have a few questions and kindly request your guidance:Please confirm if we can loa...
Hello,I’m working on STM32H7 firmware using the STM32 Cryptographic Library (CryptoLib) for firmware decryption.I have the following scenario:Firmware is encrypted with AES128-GCM.Integrity and authenticity are verified separately using ECDSA + SHA-2...
To secure USB against unauthorized usage while maintaining regular operation, implement authentication and encryption for all USB communication, ensuring only authorized devices or users can access the interface for parameter and log management, open...
Hi All, Does anyone know how to enable the MCO2(PC9) output after secure manager enabled? its work in project without secure manager and it could be enabled in systemClock config function as below: ,but it's not work any more after secure manager o...
