I need to use hal_flash/hal_flash_ex/hal_flash_ramfunc but all of my normal peripherals are LL so the base hal drivers are not loaded into my project when I GENERATE CODE. My workaround is to include something like CRC/HAL to load a bunch of hal dri...
Hello,I am trying to add a new crypto scheme in the SBSFU application for STM32H7B3-DK.I have implemented RSA_PKCS1v15_Verify() function using STCrypto lib in the SE_CRYPTO_Authenticate_Metadata() for RSA verification. As per my understanding the RSA...
I am trying to use the cryptographic library on a STM32F103, but I cannot find any documentation that is in line with the library and functions.In UM1924 rev.8 we still speak of version 3, but I cannot find the mnual consideration of rev. 4.0.1 (ther...
Hi, I was testing the different levels of read protection and when I activated RDP 2, I lost full access to my board. I would like to know if there is any way to regain access (do a downgrade), despite losing all the content I had installed, somethin...
I am trying to write a user key to CKS on a P-NUCLEO-WB55 using either STM32CubeProgrammer or STM32_Programmer_CLI and the SWD interface. I am able to start the FUS no problem, as shown here:C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProg...

Hello, I'm working for an MNC and we use stm32l431cc. And I have to implement firmware updates over the air.physical connection:TARGET DEVICE <---UART----> External IOT DEVICE (GSM MODULE) which can be plugged in and out <----> Cloud service.For the ...
Hi,My custom SBSFU_UserApp.bin failed the header signature verification in slot SLOT_ACTIVE_1 when I tried to execute it on the STM32H7B3I-DK board.To replace ECDSA with RSA signing verification, I have changed se_crypto_bootloader.c.SECoreBin projec...
Referring to "mapping_sbsfu.h" file of the example "2_Images_OSC" of STM32f769I-Discovery, seems the DTCM and SRAM2 are not used in the project.So does it have a reason?
