Hello happy taxpayers[EDIT #1]I forgot to say that what is really working is that is, from non secure app, I try to write in secure SRAM, then I end in the secure fault handler of my secure app. So, in this direction it's really clear the expected be...
I am trying to get application level RDP progression into my bootloader to kind of self protect my firmware once it has started. I have set level 1 and the firmware still runs and I can no longer read out flash or debug, so that's the positive side.B...
Hi,I want to add a function in the code to update the option bytes and set the read protection to level 1. However, this version sometimes bricks the MCU (STM32G030K8) after flashing, making it unable to connect with the J-Link.Q1: Why am I unable t...
Hello,Unless I'm wrong, the architecture of the TFM application as described in UM2851 seems not to allow the assignment of a peripheral (e.g. a LED pin) to the Secure context of TrustZone as it is the case with simple TrustZone applications. The UM2...
Hello,I enabled STSAFE in the TFM app on a B-U585I-IOT02A board following the instructions shown in UM2851, by adding the PSA_USE_SE_ST compile switch in the TFM_Appli secure and non-secure projects, and I enabled the USE_PAIRING switch.When I run th...
Hello,I am trying to run OEMiRoT on STM32H503 (NUCLEO-H503RB - MB1814B).I followed the instructions specified: https://wiki.st.com/stm32mcu/wiki/Security:How_to_start_with_OEMiRoT_on_STM32H503In step 6 ("Flash new User application in CLOSED state") a...
Hello,I am working on a project using mbedTLS and Keil MDK to make an HTTPS server running on an STM32F777. To speed up encryption/decryption, I am trying to make use of the CRYP coprocessor (mostly focusing on speeding up AES GCM calculations). My i...
Hello,I am using STM32H750 and X-Cube-Crypto lib. I am working on a secure boot and want to calculate the app Hash value to check integrity. The library works fine for STM32L5 Mcu (Already tested) but not with STM32H750. I verified that I am using th...
hi i'm new in stm32.i'm using stm32 cryptographic library (cmox) for encrypt my data.while using the library, i'm experiencing some strange.I'm trying to encrypt data after initializing the library and generating the encryption key, but the encryptio...
Hello,I am developing a new product with the STM32h753, and we are trying to use both SBSFU and SFI. The secure boot implementation was already integrated and working before tackling SFI. When tackling SFI, I first tested it with a simple program wit...
