Hi,I have a question about choosing some fairly basic security settings for an STM32H5.We are developing a system that uses both G4 and H5 micros. We have developed a largely common bootloader that receives a signed encrypted application over various...
Typical bootloaders (including some of ST's built-in bootloaders for other processors) typically allow a code image to be loaded into the processor via some kind of serial link (UART, SPI, CAN, etc), without needing an ST-Link or other debug hardware...

Hi, I'm building a medical device that will use an STM32 MCU and requires secure boot and secure firmware updates (over USB-C preferably). I have little experience with implementing secure bootloaders, and am looking for a solution that could allow m...
In STM32Cube_FW_H7RS_V1.3.0, file Projects/STM32H7S78-DK/Applications/ROT/OEMiROT_Boot/Inc/flash_layout.h:The macro OEMIROT_LOAD_AND_RUN has 3 possible settings, and we're using the NO_LOAD_AND_RUN to execute code (in external flash) in place.However...
We are seeing a very odd data corruption issue which is highly repeatable, and appears to be related to a configuration setting which we haven't yet identified.In our system (running on an STM32H7S7), we're using the STiROT + OEMuROT secure bootloade...
Firmware Package: STM32Cube_FW_H5_V1.6.0 Product ProblemDA regression fails with timeout. I cannot recover the board. I was trying to run the STiROT Template example (STiROT_Appli) on the STM32H573I-DK board. 1. I ran a custom provisioning script (ba...
Hi everyone,I am trying to generate a professional SBOM for my project.I have a few questions regarding the best workflow:Tooling & Detection: What the best tool to generate the SBOM.I tried using ScanCode, but it didn't find any component in my proj...
In OEMiROT_Boot/Src/low_level_ext_flash.c, function Ext_Flash_EraseSector(), a call is made to EXTMEM_MemoryMappedMode() immediately before the sector erase takes place, to temporarily disable memory-mapped mode for the external flash, with the func...
