Hi,I'm working on the evalboard of the STM32H563. With a plain project I'm able to activate the memory mapped mode of a plugged nor-flash.If I change the project to have Trustzone activated and divided the application in secure/non-secure part, I'm n...
Hi everyone, I'm working on integrating the SBSFU (Secure Boot and Secure Firmware Update) into an existing project for a custom board using an STM32U585 microcontroller.At this stage of the project, I am trying to include the SBSFU_Boot (https://git...
Hello,I have a DCMIPP example application in FSBL that runs fine on an STM32N6570 Disco when loading it with the Disco board's built-in ST-Link. It has a DCMIPP_HandleType Def structure with hdcmipp.Instance that needs to access secure peripheral mem...
I'm trying to get the Debug Authentication provisioning to work. I managed to write it from within the application, but then I found the errata sheet(es0565-stm32h562xx563xx573xx-device-errata-stmicroelectronics.pdf) which states otherwise:"Chapter 2...
Hi all,I’m working with the W5500 Ethernet module over SPI on an STM32 with Trust-zone enabled. The W5500 requires a clock source for proper operation, which I’m trying to provide using the MCO on the CS pin.The issue is that I’m not able to enable t...
The following repository contains examples for creating 'normal' type of external loaders, i.e., to be used with the "-el" argument of the STM32CubeProgrammer (e.g., with output "STM32CubeProgrammer/bin/ExternalLoader/MX66UW1G45G_STM32H7S78-DK.stldr"...
Dear,I am writing to inquire about the inclusion of a validity period in the debug authentication certificates used with the STM32H7S3 microcontroller.My project requires that the debug access certificates I provision have a limited, defined lifespan...
Hi,We are using SBSFU and FreeRTOS in STM32H755xI. We are planning to use Zephyr RTOS in STM32H755xI. Can I use SBSFU bootloader in Zephyr RTOS?--Muthukrishnan
Hello Support Team,for testing purposes i am using the H533NucleoBoard. I can load my firmware into the MCU and the firmware is running as expected. I want use the final product in ProductionState: closed.The problem is, the firmware isn't running an...
Hi everyone,I have a question regarding SFI Option Bytes for the STM32H753ZI (Nucleo-H753ZI).Question:Which option bytes should I pick, since there are a lot of different combinations available: 1. Generated by TrustedPackageCreator: FLASH_OPTSR_PRG,...
