Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Hi support team and developper community. Happy new year to all. I have a project including Secure Manager and a Non-Secure application on a STM32H573 platform. My non-secure app is modeled after the SMAK_Appli app provided within STM32Cube. I used ...
I'm curious what is the best way to debug a User Application when using SBSFU on a STM32.Of course the security mechanisms in SBSFU/SECore must be disabled to allow debugging at all and basically just downloading the UserApplication and debug it with...
Hello, I have a problem with a STM32H725, the Option byte RDP is locked to the value BB.In fact, I try to change other option bytes and it always fail with this error: " Error: Option Byte Programming failed Or modified by application after OB_LAUNCH...
I get a stm32l562e-dk board, when I use the following figure setting to connect to the board and modify nSWBOOT0 bit to 0(TZEN=1). I found that I can not connect to the board using "Hot plug" or "Normal" mode.whether I FOREVER lost the device? In ad...
Hello,I’m working on a project using the STM32WLxx MCU and need guidance on implementing asymmetric cryptography (encryption, decryption, and key management). The MCU supports AES for symmetric encryption, but I’m looking for a solution for asymmetri...
Hi,I am working on SBSFU with stm32L476 Nucleo Board I am following the steps of Tutorial Security Part6 - STM32 security ecosystem - 02 Building the SBSFUI have Download Stm32CubeExpansion_SBFU_V2.6 but which is the highlighted directory are missing...
Where can I make the Encryption Option "Disable"?
hiplease only ST Employee answer this questioni use this code for enable RDP LEVEL 1 for STM32H743 and STM32F407Can this code alone protect the program in the flash from any type of attack to read the program in the microcontroller?Will it be possi...
I am using the STM32H7B0VBT6 microcontroller, which has limited internal flash memory. To implement Secure Boot and Secure Firmware Update (SBSFU), I have connected an external W25Q256JVIQ flash memory to the MCU via Quad SPI. Is it possible to sto...
Hello,I am trying to use below file to enable RDP 2 on an STM32 L552 controller.wiki.segger.com/images/7/78/STM32L5_Lock.jflash This has exit step "ExitStep21_Action" that set the DRP Level 1, However, I need to set RDP Level 2 by setting the value a...
