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...
Is there any configuration we need to modify in prepareimage.py to overcome this error "ERROR: overlapped zone is not empty" or any other configuration?Below is output.txt file.python /Users/username/Downloads/STM32Cube_FW_WL_V1.1.0/Middlewares/ST/ST...
Hello!I have a problem with STM32L496RG booting from flash after activating readout protection level 1. The issue is that MCU seems to get stuck in system bootloader code. The only way to get it to boot from main flash is to apply power on reset.Accr...
Hello guys,I was setting up my STM32CubeIDE to use the SBSFU sample projets. I'm facing a issue with SECore engine, more specific the postbuild.sh script.When i compile SE, i get the following message:ln: failed to create symbolic link '../../postbui...
Hi everyone,I am using STM32F469/STM32F479 and want to integrate SBSFU with an SPI flash. Basically the active image is in MCU's 1 Mbytes flash and downloaded image is in the external flash. There are several questions I would like to know before I s...
