How can we map HDPL levels to ST boot/ User Boot / User secure app/ user unsecure app in STM32H573 controller ? In user flash if I want to place my OEM ROT , OEM uROT, Secure App and Unsecure App, How do I map each HDPL level to corresponding boot or...
I tried to provision Secure Manager 1.2 to my DK board, and got the following error messages in the provisioning.log:2024-11-10 15:49:30,796 - root - DEBUG - Error: SFI command is not supported for the current device configuration using STLINK interf...
I am encountering an issue in the development of the TrustZone application related to the UART in secure non-privileged mode.I want to switch to non-privileged mode when in secure and privileged mode. This transition works correctly. However, I have ...
I have finally managed to get the SBSFU to work on my STM32F4-Discovery board. I've been working on this over the past month until I figured it out and got it to work. For some reason, I couldn't get the 2_Image version to work on my hardware. I bel...
Dear STMicroelectronics,The problem described here: OEMiROT example flash protect sector problem seems to still be present in STM32Cube_FW_H5_V1.4.0. I tested to rebuild Projects/NUCLEO-H563ZI/ROT_Provisioning/OEMiROT from STM32CubeIDE after changing...
Hi,Our product proposal to a client has at the root of its security an STM32H533 running our OEM Bootloader and Secure Application only. The Product State will be either Closed or Locked (as yet undecided) and we will be storing encryption keys used...
I am using a stm32l451cet6 micro controller chip in my PCB. I want to make the flash memory read protected. For this I use the following code snippet - while (HAL_FLASH_Unlock() != HAL_OK) { ; } ...
Hello,i'm using stm32h747igt6 microcontroller, it has two cores Arm Cortex-M7 + Cortex-M4, i'm currently working on core m7, and i have integrated STM32 cryptographic firmware library software expansion for STM32Cube for some security features in my ...
Hello all, We are working on STM32 Secure bootloader for STM32H7B3RIT6 MCU. For this we taken reference code from X-CUBE-SBSFU STM32H7B3I-DK .As of now we have successfully migrated the SBSFU & SECORE code for STM32H7B3I-DK to Our MCU.We have prepa...
Hi,I try to use the SBSFU in a project with a STM32F722 and so far it works to flash an initial firmware. Now what I would like to do is to update the firmware and for that, since I can only use one image because of the limited flash size, I corrupt ...
