Hi.. Geeks From few days I'm playing with SBSFU. I'm using default application SBSFU files (STM32L496G-Discovery_AWS) with custom user application with STM32L496ZG The default code was ported on STM32L496AG which is x-cube AWS I have simply adopted i...
Hello Experts,I am trying to integrate the "STM32 Cryptographic Library" to my application. The library name is "libSTM32CryptographicV3.1.3_CM4_GCC_ot_fpu.a".How big is the stack size used by this library?When I used the library, RTOS got a hard f...
I am trying to sign and verify messages with the STM32 CryptoLibrary and the ED25519 signing functionality.But the created signature is not the same as the created ED25519 signature created with the CryptoPP library.My code for generating a signature...
Hi,I could successfully integrate the SBSFU feature to our application. everything goes well until I get a failure after swapping the images.FW signature is not getting verified and function SE_SP_SMUGGLE is returning SE_ERROR which is causing the er...
Hello, I am looking to port one the examples from X-CUBE-SBSFU to get it running on my Nucleo H745ZI-Q. For some background I am very new to the world of STM32 and STM32Cube and I am trying to learn to get this feature running on this nucleo board I ...
Hi, I want to do some AES128 evaluation, I need a discovery board, no need other function,What is the recommend(simple and cheap) discovery board? Thanks a lot.Ken
I'm in the process of integrating the SBSFU into a project.I got stuck when the decryption process seemed to hang.After I got the SeCoreBin symbols loaded I realized that it was waiting for CPU2 to become active (specifically while waiting for FLAG_W...
I'm working with an STM32F04, and I'd like to change the option bytes so that my firmware can't be read back out after the device is programmed. I can tell from documentation I need to set the RDP byte to something besides 0xAA or 0xCC, but there isn...
