STM32 MCUs Security

What are Boot Steps of STM32H7 Secure Mode

As per my understanding Secure Mode of STM32H7 as follows:RESET => Enter System Boot loader => Program OB register content => If (SECURITY) => RSS Boot => Configure Secure User Memory => Jump to Secure User memory on User Flash.I have two open questi...

is the Asymmetric Cryptography supports ECC NIST256p keys only ..?? Because i tried to generate ECC private key with help of "secp256k1" and got compilation error as NOT SUPPORTED,

Self Generation script is like this :def generate():       return ECDSA256P1(SigningKey.generate(curve=NIST256p))KEY EXTRACTIONkey = SigningKey.from_pem(pem)       if key.curve.name == 'NIST256p':           return ECDSA256P1(key)       else:         ...

Hello guys,I'm trying to use the sample project given in the MOOC, and I'm getting compilation errors. The below is the error message.../STM32_Cryptographic/legacy_v3/src/hash/legacy_v3_sha1.c:20:10: fatal error: hash/legacy_v3_sha1.h: No such file o...

Is there a way to use the CLI to set the security read back in the option bits and also execute the start command?

I would like to set the security fuse but also have the application start running. I can set the read protection but after that I can no longer communicate with the unit. Likewise I can start the application using the start command -s but after that ...

stm32l476vcx controller how can internal flash write and read and calculate crc

Solved: STM32H745 CRC->POL Register wrong address in STM32H745_CM4_Peripherals.xml

In the STM32H745_CM4_Peripherals.xml is an 0x10 address offset... correct is 0x14.That is the reason, that I don't see by debugging the value I wrote to this register.
