Hello everyone,i am trying to enable the secure user memory on the stm32h743 using the x-cube-sbsfu project and have the following problem:After activating the security bit, the value of the OPTSR_PRG flash register is not changing, so the security b...
Hello. I'm trying to obtain CRC value from CRC peripheral. It's supposed to give me 8 bit number. Instead it gives me 32 bit number. What am I doing wrong? Below is the code and program outputs. /* USER CODE BEGIN Header */ /** ********************...
HiWhen I was returning from RDP level 1 to 0 the stm32cube programmer program crashed and now every time I try to access the microcontroller several different cases happen:1- Connect and instantly lose the connection giving the next error: Error: Dat...
Hello,I am using the X-CUBE-SBSFU package with the KMS to perform firmware update on my ST MCU.To verify the authenticity of the firmware I use ECDSA. However, I don't understand why I only need to provide a private key but not the public key. If I u...
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 ...
I'm successfully implemented IAP for stm32h745. so I wish upgrade to sbsfu.Sbsfu has security firmware upgrade. When i implement for IAP, Firmware file was merged cm4, cm7 binary file using Srecord.If I merge files, won't the integrity of the firmwar...
Hi Team,I am working on a project involving the STM32H5 microcontroller and I am in need of information on how to manage the keys securely for encryption and decryption. I have been unable to find a document that covers this topic specifically for th...
