I need to know the programmability of STSAFE A1100.
I am looking into STSAFE A1100 to implement authentication. I noticed it is referred to as an IC instead of an MCU. Does it mean it is not programmable? Do we have to use it as is?

RDP settings to disable main memory read
Hello there,I am trying to find the right RDP config for the STM32G0 MCU. My aim is the following functionality:User code can read/ write the flash,Bootloader/ external SWD debugger cannot read the flash,Bootloader/ external SWD debugger can erase an...
Possibility to block SWD access on reset and enable it via software.
Hello,I am currently using STM32L010 MCU in my application where we have UART and SWD lines exposed to be accessed only by service personnel (under a cover but still accessible without dismantling the device). Since we want to have a possibility to p...

I'm trying to build the SBSFU project for board STM32H7B3I-DK (2_Images_ExtFlash) but am unable to. Everything does build fine but it fails on the last step, the postbuild.sh step, at prepareimage.py enc.I'm using STM32CubeIDE 1.5.1 on LinuxThis is t...
SBSFU Memory fault when SFU_MPU_PROTECT_ENABLE is used
We have ported STM32CubeExpansion_SBSFU_V2.4.0 to use STM32H7B0 instead of the STM32H7B3-DK.When I enable SFU_MPU_PROTECT_ENABLE the bootloader generates MEMORY FAULT! when starting up and not yet called user application. I have tried to debug as muc...
Using CHCHA20 crypto functions (STM32 CryptoLib 3.1.5)
Hello everyone,I was wondering the proper way to use the STM32_CHACHA_20_Encrypt() and STM32_CHACHA_20_Decrypt() functions available on the ST CryptoLib. I run the standard demo code on a STM32F072C8 MCU and it apparently run correctly, returning PAS...
Resolved! STM32L476G-EVAL CRYP Examples Problem
The code from the 1.16 example builds fine in the EWARM. It writes the source blocks to the terminal, but as I see in the debugger, it fails to encrypt the input block. That times out as it fails to return a HAL_OK status. /* Start decrypting aCypher...
NUCLEO-L152RE_2_Images_UserApp post build fails
I have the nucleo l152RE board and am trying to use this for following the mooc on sbsfu. It is possible for me to build (in cube IDE) both SECoreBin and SBSFU images. however, when building the UserApp it fails on the postbuild script. During build,...
Problem with MPU bufferable and cacheable definitions for UserApp execution
I am using x-cube-sbsfu version 2.4.0 on a custom designed board using the STM32F722. I have ported the single slot code (1_Image) for the STM32F769I-Discovery board to the custom board. I have come across what looks like an error in the sfu_low_leve...
