STM32 MCUs Security

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.

Recommended CPU Frequency for SBSFU ??

SBSFU involved signing verification and encryption/decryption related activities.Also crypto processing is required to implement SBSFU solutions.So, what is the recommended CPU Clock frequency to implement SBSFU solutions ??

Chip Vulnerabilities and STM32 Hacking

Hi - I am new to hardware security researching, so I thought start with a simple STM32 MCU to improve my skills.I can develop simple applications and upload it to flash, everything is ok so far. But I wonder how can I hack the device I developed. For...

Linking SECoreBin to SBSFU, How it works ??

From X-CUBE-SBSFU examples, we link SECoreBin binary to SBSFU project, to access Secure Engine APIs.Even though we are linking SECoreBin, but how it will address at linking right function address offset ?? It means how SBSFU project get SECoreBin fun...

SB and SFU isolated?

Hey guys, I want to perform a firmware upgrade over the air. And use a UART to connect to IoT device.I use stm32l431xx and it contains hardware for symmetric encryption. And the host device which sends the binary uses stm32l496 has SBSFU.So I have a ...

When I am building the application for SBSFU for STM32L476 on CubeIDE, I get the following error when I compile the first project : SECoreBin
