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,...
Dear STMicroelectronics Community members,I am currently evaluating STM32 microcontrollers for a project that requires strong cryptographic capabilities. Our goal is to implement hybrid encryption, meaning we need hardware support for both symmetric ...
HiI am trying to perform a secure boot implementation in STM32F439ZIT6. The datasheet shows that, there is Hash, RNG, AECS and TDES. Can I perform secure boot functionality using only STM32F439ZIT6 without using any external chip and if so, are there...
Hello,I am working with Nucleo-STM32U385RG to implement the Root of Trust (Secure Boot) feature, following the wiki guide: https://wiki.st.com/stm32mcu/wiki/Security:How_to_start_with_OEMiRoT_on_STM32U3My test environment is STM32Cube_FW_U3_V1.2.0.Du...
Hello,I am trying to configure the secure memory in Secure Protection Bank 1 of options bytes section and for this I have followed the STM32 MOOC tutorial to understand the concept of using secure boot code. But I am facing issues as the base address...
