Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Hello, I'm looking for some advice on how to progress, beginning from a fairly novice position, with a secure bootloader. I'm beginning a project where at least a secure update process (where the existing application does the update) is desired. Id...
Hi,I'm developing a secure boot application for STM32H563ZI microcontroller. I started with a very simple application following ST template code and tutorials like this one: https://wiki.st.com/stm32mcu/wiki/Security:How_to_start_with_STM32CubeMX_OEM...
I've downloaded archive "en.STM32CubeExpansion_Crypto_v4.0.1.zip", now I'm trying to install it in STM32CubeMX with "From Local..." feature, but I'm getting error. How can I install the library in CubeMX?Thank you.
Hi everyone,We’ve been using the XCUBE-SBSFU bootloader in our industrial-grade project and recently noticed that SBSFU is now labeled as a legacy bootloader. It seems the new recommended bootloader is based on MCUBoot. Additionally, I’ve come across...
What I want to achieve:During startup all code is verified, starting with SMiRoT (as root-of-trust) then SMuRoT, then SecureManager then non-secure application.If the application has been modified (vberification fails) the startup shall end in system...
Hello, I have a problem with setting readout protection in the STM32L496 device in software. The protection is set to "BB". After setting and power on reset, the microcontroller seems to not work (it looks like as if it was "stuck up"). I connected t...
I try to enable the PCROP Feature on a STM32H753I am using the STM32CubeProgrammer and connect via ST-Link V2After connecting, I go to the "OB" page and set the PROT_AREA_END1 value to 0xFFF and activate the DMEP1Then I press the "Apply" button and t...
Hello ST team,I am studying the flash security mechanisms (RDP, WRP, PCROP) on STM32L476RG and I understand how to configure Option Bytes using STM32CubeProgrammer or firmware.What I am trying to understand is the hardware-level enforcement flow of O...
Hello ST, I am working with STM32WBA52 and I am no longer able to connect to the device using STM32CubeProgrammer. When trying to connect, I got the following error: The interface firmware FAILED to reset/halt the target MCU A fail.txt file is also g...
Hello,starting from the example application of the OEMiRot boot project, I noticed that the NS application size is limited to 640kB in the flash_layout.h (#define FLASH_NS_PARTITION_SIZE (0xA0000) /* 640 KB for NS partition */)Since there is 1MB ava...
