Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
If, like me, you are attempting to use this device and believe there are gaps in the information available, you are correct. However, the information you seek, plus additional advice and assistance is available from ST, you simply have to ask via a t...
What is the meaning of the FLASH_OBKCR.NEXTKL field while executing within HDPL_0 (e.g., during execution of ST RSS)?This question might seem irrelevant to me as I'm a user and user code will never execute within HDPL_0, but it might be important fro...

Hi,I'm working on STM32L496 for some security application, as per L4 series documents I see that L4 series controllers has AES hardware, but in my IOC settings under security option I don't see the AES. Why is this? does it mean STM32L496 doesn't hav...
Hi Team, I am trying to add a Secondary/custom bootloader in SBSFU. But not able to figure it out how to do it. I changed memory for active slot area and used the same area for custom bootloader in both linker file of both SBSFU and custom bootloade...
HiI've been trying to understand what level of support is available for the H573 security features in Zephyr RTOS with mcuboot but either can't find any information or no one replies to my comments.I have a Zephyr sysbuild build working where mcuboot...
I'm currently working on a final project titled "Design and Communication Security Mechanisms in an Embedded Gateway Module for Electric Vehicle Networks." I'll be creating a security mechanism using AES-128 and a hash function, and securing data fro...
Hi, I've been working on porting the SBSFU onto a STM32H7A series with my custom gcc-arm build environment.The example project I am referring to is: x-cube-sbsfu-v2-7-0\STM32CubeExpansion_SBSFU_V2.7.0\Projects\STM32H7B3I-DK\Applications\2_Images.Ever...
This works fine in an app without SM but when I run this from a non-secure app together with SM, the last step fails. This is the code: // Enable access to RTC and backup domain HAL_PWR_EnableBkUpAccess(); if (__HAL_RCC_GET_FLAG(RCC_FLAG_LSERDY...
Hi, I'm using 3 channels of ADC4 with GPDMA1 (channel 4) in secure world of a TrustZone-project and the DMA-buffer stays always 0. The same ADC/DMA-configuration with the same application code (all mnus the security aspects) are working fine without ...
