Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Hello,I am trying to use the UART peripheral in the secure zone via interrupts in SBSFU for the STM32U575 microcontroller, but I am not receiving any data. I have used the same code for the non-secure region, and it correctly receives the first value...
Using STM32WB55, for the SBSFU 2 image bootloader ST provide a linker script for the user application. This works, but the user application itself can only be updated by uploading a new application from within the application using YMODEM, or exiting...
Hello everyone, Security is a key requirement in my current project, and while researching security for embedded systems I came across STM32 TrustZone and Trusted Firmware‑M (TF‑M). I’m working with an STM32L5 series MCU (which supports both TrustZon...
Hello dear friends,this is my first post and I need your help with an issue I have. I designed some devices based on STM32C031C6. I use an I2C command to jump to bootloader and I upload the new firmware via I2C also from a microcomputer using the stm...
Hello, I've got STM32H53 MCU and trying to use hardware CCM accelerator as alternative CCM for mbedtls library.I've took HAL implementation from the repository STM32Cube_FW_H7_V1.11.2/Projects/STM32H743I-EVAL/Applications/mbedTLS/Crypto_Selftest/Src/...
Hello,I am new to the STM32 development environment and real-time programming. I have the STM32H573I-DK development board and have followed the workshop provided by ST, available on the wiki:https://wiki.stmicroelectronics.cn/stm32mcu/wiki/Security:H...
I am using X-CUBE-MATTER v1.1.1. I understand that it is possible to use the DAC and PAI provided by CommScope using the project STM_provisioning. Please tell me more about STM_provisioning. Also, please tell me how to create STM_provisioning in ligh...
Hi,I am Working on SBSFU. I have Flashed the STM32H753zi example code after flashing i am not able to flash from programmer. even after changing the option bytes RDP level 0 is set.I have Connect another working board of stm32h753zi board i compared ...
Hello.If i set the product state to CLOSED (0x72) without TZ-enabled (TZEN: 0xC3),i can't access the device and the OBK-Keystore from outside.But if i write a user program, i can read the whole OBK-Keystore at:FLASH_OBK_BASE_S + 0x0100;So perhaps it...
Hi, I am working on OEMiROT bootloader for STM32H523. I have copied big parts of the ST OEMiROT example project from H533 example as this is the closest MCU to H523 from the flash memory layout perspectives. However, it is taking ridiculously too lon...
