Hello guys!How are u all?I'm having few issues to develop self-test on my application. I setup everything from the SBSFU side to check image handling flags, and its working fine. I'm able to set my new firmware to self-test state and check the state ...
Hello,I have a system with one STM32L562QEI6 and one STM32F405RGT6, that is the main MCU.They communicate with USART interface.In the main CPU, boot0 and boot1 pins are phisically connected to VCC or GND through some resistors, so I can enter boot mo...
Hello,I am trying to run the Secure boot feature on STM32L433RC using the SBSFU library example project (single image slot). The example project I am modifying is STM32L432KC board. Below are the modification/steps I made to example project to run on...
HI,I have successfully implemented encryption in my project using STM32 cryptographic firmware library software expansion for STM32Cube. It works fine with 128 bit AES encryption (i.e. using 16 bytes long AES key). However, I need to implement 256 ...
Hello everyone,I am trying to build SECoreBin, but the build fails with prebuild.sh. All python requirements listed in requirements.txt are installed, but the error is following:ImportError: No module named Cryptodome.CipherAnd even more: What should...
HelloI would like to use the same UART that is used in SBSFU, to communicate with the host PC for service purposes. Is it possible? Maybe create kind of a wrapper interface like "press 1 for sbsfu, 2 for logs"? A little bit confused how to implement...
Hi,I just downloaded the latest cryptolib v4 and read in the docs that it is not compatible with v3 anymore.Are there any instructions how to use it with the "STM32 Security in practice" workshop?Thanks,Anguel
HelloI'm having trouble calculating crc. I am using STM32F401 with cube ide. The correct crc occurs on crccalc.com. But I couldn't run CRC-8 with MCU. I have looked at the examples, but when I try it gives different results. Can you provide a worki...
I am using STM32H747BI MCU and I have one project to write the data to flash memory. I am using core 7 to write the data to flash. While writing, I have to encrypt the data. So I requested cryptographic library software expansion from STM32 and they ...
I am exploring the security feature of STM32WL55JC via Applications/BFU_1_Slot using latest firmware STM32Cube_FW_WL_V1.1.0I am not sure what I am doing wrong and I have followed youtube and readme.txt. I was able to compile as below and upload STM32...
