Our own non-secure application is based on "SMAK_Appli" in the STM32TRUSTEE-SM example and in principle, it works, but debugging is giving me issues. This is with STM32CubeIDE latest version and all tools software and firmware updated to their latest...
Hi,I am using STM32H56x with OEMiROT_Boot example project, and I use MCUBOOT_SWAP_USING_SCRATCH to install application images, is there an API like boot_set_confirmed( ) can used by secure applicaiton code, or a confirmation flag in SRAM like STM32H7...
Hi, I am working with the SBSFU_Boot on the STM32U5A9 chip. After the SBSFU_Loader has written the update image into internal memory, a reset happens in order for the SBSFU_Boot to write the image to be booted. When performing the update, it ends up ...
Hello, I have an STM32H755 nucleo board and I want to use the secure memory area features but I need to clarify my understanding of the reference manual "rm0399" and some follow up questions.My understanding is that:From my normal code (non-secure) i...
All the provided examples are using USART YMODEM to transfer data. I know, that it really doesn't matter what kind of protocol you use as long as image is placed in a correct place in the memory, but I wonder if I can use DFU feature to update firmwa...
Hi Team,Firmware file are just signed not encrypted through STM32 SigningTool - stm32mcu (STM32_SigningTool_CLI.exe) after generating public and private keys through STM32_KeyGen_CLI.exe.Public key in raw 64 bytes is provided to bootloader_main.c as ...
HelloDo I unterstand correctly that the recommended secure boot option for STM32L4 is SBSFU?It seems that the only resource on how to get started with examples is the playlist on YouTube where a non signed exe from google drive has to be installed.Is...
Hi everyone,Hi @Jocelyn RICARD, @D.Botelho @Jocelyn RICARDyou made this small bootloader example for testing H7 security features, e.g. RDP:https://community.st.com/ysqtg83639/attachments/ysqtg83639/mcu-security-forum/6051/1/STM32H753_SecureMem_Examp...
Hi ST Team, I am using STM32H7S78-DK development board.I have read and tested following article:https://wiki.st.com/stm32mcu/wiki/Security:STiRoT_for_STM32H7Shttps://wiki.st.com/stm32mcu/wiki/Security:OEMiRoT_OEMuRoT_for_STM32H7Shttps://wiki.st.com/s...
On a secured STM32H7Sx device (in CLOSED or LOCKED product state), what is the recommended way of passing volatile data to lower HDPL levels?According to the reference manual, the SBS_RSSCMDR register can be used to pass volatile data from HDPL 1, 2 ...
