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 have the NUCLEO-H753ZI example running on my board. All works fine without the security features. When I enable both the SFU_MPU_PROTECT_ENABLE and SFU_IWDG_PROTECT_ENABLE. I keep having a watchdog when it tries to execute the firmware. I commented...
