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...
I'm using STM32L562VET6, please tell me where I can find "X-CUBE-CRYPTOLIB" support Cortex-M33.Thanks,QiZhang
Hi, Trying to turn on RDP just before I get a product out to market. Can unlock and erase Option RDP bits to 0xFFFF but cannot seem to write the option bit to set RDP byte to 0x00FF. This leaves the devices bricked on the next reboot. Can't era...
Hello everybody,we're currently discussing product tampering and intellectual property (IP-) protection for a new product.I read a lot about SBSFU, the STSAFE processors and KMS memory in some STM32 µCs, but some things I may have not 100% understood...
Hi,I am migrating some code from an STM32F745 to an STM32H743.I came into some trouble while using the crypto library and the hardware CRC at the same time.The STM32H743 crypto library resets the CRC DR register every time AES_CBC_Decrypt_Append is c...
