STM32 MCUs Security

When using X-cube-sbsfu, why is swap area size constrained to be at least equal to the size of the largest flash sector? Is there a way to modify SBSFU to work with a smaller swap area?

On STM32F746, largest sector is 256K and total flash size is 1M. This means that 1/4th of our flash is lost to the swap area. As a result, we do not have enough flash memory left to implement the dual image variant. We are now trying to optimize the ...

How to make X-CUBE-CRYPTOLIB V3.1.0 to perform AES-192 encryption compatible with other online tools?

I am using X-CUBE-CRYPTOLIB V3.1.0 on STM32L0 to perform AES-192 encryption with a 192-bits key and 128-bits IV. Encrypted Data by STM32L0 can be correctly decrypted by STM32L0 using the same library.However, when I copy the encrypted data, key and I...

What is the exact expected sequence for the YMODEM protocol used in IAP and SBSFU?

Hello,for some STM32 controllers ST offers for application-update the IAP and SBSFU modules:https://www.st.com/en/embedded-software/x-cube-iap-usart.htmlhttps://www.st.com/content/st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm32-e...

HI, I'm working with STM32F103R8 on AES .The input key which I enter is not stored properly I tried by simply displaying the key through UART.Here I missed the 13th to 16th elements.This happens only for a 32byte array.

Can anyone help me with this,I have attached the code below.Thanks in Advance

Hi., I'm beginner for atollic true studio. i need to work with SHA- 256 and AES-128 algorithm for Stm32F series plz help me for the development. There is any library availability plz share

STM32 capabilities

Hi,I would like to move my project to STM32 from another MCU.There are some requirements that I have to comply with and I would like to know if STM32 is a good idea or not.I need to be able to flash the firmware using USB without an USB to UART conve...

Extend bytes for application fw version in the image header

For our application, we require more than 2 bytes to identify the fw version. However, the current SBSFU has only 2 bytes fw version in the header. What is the easiest way to add a few more bytes for fw version? Thanks!

I'm working with a STM32L476 MCU in Atollic, and I have a problem because Read protection mode.

Does anyone know something about it or similar cases?Is there some registers in HSE clock that can affect the RDP registers?Is it possible to be a bug in CubeMX?Or the problem is in my hardware?Thank you.
