Currently, i working on the nucleo-L552zeq and i run the SBSFU exemple propose by the cubeL5. i use the script regression.sh and the script the SBSFU_UPDATE.sh to initialize the board and download the firmware. this example can work normally on the b...
I have updated the startup scripts from the MOOC to work with the stm32l152re. However, when I build the user app and flash it onto the MCU I only get the text from the SBSFU in the terminal. It automatically wants to receive a new user firmware:= [S...

Hi all, I am trying to make an own private key on the SBSFU, if anyone has succeeded in this could you pass me the steps which I have to proceed with. I went through An5056, then I tried to change ECCkey1 but in some cases. it works and it is upgradi...
Hello,I want to integrate a secure boot and secure software update (SBSFU) on a nucleo H753ZI board.I downloaded the software from https://www.st.com/en/embedded-software/x-cube-sbsfu.html and followed the steps to compile the three programs (SECore,...
Hi, I'm developing a zephyr application that I want to run on STM32L562E-DK. When my new development Kit arrived, I went through zephyr example samples to test it. I saw a sample that was using Arm TrustZone technology with TF-M, as it was new to me ...
I've managed to configure the STM32 CRC such that it can create the standard CRC-32 as per this article - https://stackoverflow.com/questions/39646441/how-to-set-stm32-to-generate-standard-crc32. However, this CRC does not match Ethernet spec.Is ther...
I have implemented sbsfu on my board. It is running. If I download a new firmware out of my user-app the new firmware is loaded, the flash is swaped and the new firmware starts up.If I reset the board, the bootloader says - Installation not validated...
