Hi,I'm using STM32CubeExpansion_Crypto_V4.0.1 library for verifying a signed firmware file on STM32F7 controller. The key-pair has been generated using openssl command-line. The firmware has been signed using the private key (PEM). The signature has ...
If LL_CRC_INDATA_REVERSE_WORD is set and 8-bit data is provided via LL_CRC_FeedData8(), the resulting CRC is not what is expected. It appears the combination of word-reversal and byte-submission mangles the submitted data in some way, when I had expe...
Hello,I am working on a project using mbedTLS and Keil MDK to make an HTTPS server running on an STM32F777. To speed up encryption/decryption, I am trying to make use of the CRYP coprocessor (mostly focusing on speeding up AES GCM calculations). My i...
The key which signs and encrypts the userApp is compiled along with the SBSFU and generates as a complete binary with keys by using STM32CubeIDE.Is there any way to change this key after the build process of SBSFU?
I have been using HAL library of cipher acceleration hardware before on the same mcu (first 100 units) without any problems, but in my last order, all mcu goes to hardfault error when i used exactly the same code on it (same binary file). By debuggin...
On running the SBSFU project on STM32F769I-DISCO board, will the boot ROM evaluate the integrity and authenticity of Secure boot. So that, the user will be sure that his/her Secure boot not replaced by others.
I build SBSFU using X-CUBE extension for STM32F769I-DISCO. Flashed the "SBSFU_UserApp.bin" file using STM32CubeProgrammer. Now I need to send UserApp.sfb file via YMODEM without using Tera TermI used,stty -F /dev/ttyACM0 115200 sb UserApp.sfb >/dev/t...
I complie STM32F769I-Discovery 2_Images demo (SBSFU\Projects\STM32F769I-Discovery\Applications\2_Images\2_Images_UserApp\MDK-ARM) with MDK KEIL 3.37.If I link project using default UserApp.sct, the packed image is right, and output.txt show below:blo...
I was searching for the security features of STM32F769I - DISCO and came to know that only STM32F77x has CRYP and HASH in the STM32F7xx series.Do STM32F769I - DISCO really have security features? If so, can you provide a relevant document regarding t...
Hey, I went through the manual of the STM Programmer command line interface and implemented a post build CRC calc with the Safety lib command -sl.C:\PROGRA~1\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe -sl MESOL_CAN_...
