Hi all,I'm working in a project (with STM32L476) in which i am building my own bootloader to perform secure boot and firmware upgrade.I have some doubt regarding this matter. is there any resources available for secure the HEX file (encrypt and decry...
I'm following the security part 6 - 02 Building the SBSFU but the final build of the UserApp always ends up with an error.Instructions are being followed EXACTLY as in the video. I'm getting a different project size when building the SBSFU, slightly ...
I have external flash of size 1MB. I want to explore the possibility of having encrypted code of size 500kb in external memory and run it through OTFDEC feature of STM32L562QE.From the reference manual I saw that provision of 4 different OTFDEC regio...
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?
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...
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...
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...
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...
