Hello,I am using the Nucleo-STM32F411RE development board and require support for cryptographic functions, particularly ECC Point Generation.input: w0, N output: Y, y Begin generate random scalar y on chosen curve Y=y×G+w0×N (G as defined NIST P-256...
Hi,I've tested freertos when trustzone is enabled, the freeRTOS can work.I've tested PSA API in "TFM_Appli\NonSecure" when freertos not used, also can work.When I try to access PSA API in "TFM_Appli\NonSecure", when freertos is used, it will trigger ...
After the build process for the project, I get a file.bin that I want to encrypt to be protected and decrypted in my chip via the bootloader. How is this done, knowing that I use stm32 cube ide?
Hello,I have successfully executed the default OEMiROT and Application projects in STM32CubeH5\Projects\NUCLEO-H563ZI\ on our prototype board based on STM32H563 1MB variant. Slight adaptations were needed for which I got plenty of support in this thr...
Hi everyone,We're working with STiROT and TrustZone on an STM32H5 (NUCLEO-H533RE), and during the provisioning process we generate the STiRoT_Config.obk file from the STiRoT_Config.xml using the Trusted Package Creator (TPC).Our question is whether t...
When I use mbedtls on my STM32U585 core board without enabling hardware acceleration, it works fine. However, when I follow the instructions in some posts and copy examples, such as the rsa_alt from SBSFU under STM32U5Cube, many errors appear, and it...
Hi,I am trying to get the OEMiROT example projects running on STM32H563 from "STM32CubeH5\Projects\NUCLEO-H563ZI\Applications\ROT". The provision.bat script fails after writing option bytes (probably after enabling TZ) and tries to reconnect to the M...
Hi, I have a firmware I wan't to give already flashed protected by PCROP to a customer. Insidie my firmware I use some standart library functions line strlen(), vsprintf and some HAL functions to manage peripherals.What is the best way to call these ...
Hi everyone,I am trying to use the X-Cube-Cryptolib library to decrypt an array encrypted by an external application.The original data has been encrypted with the AES-GCM 128 using a key of 16 bytes and an IV of 1 byte.Now, I am getting an error wher...
When I tried it, got the following error:2025-04-18 14:58:31,172 - DEBUG - Executing command: "C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe" -c port=JLINK debugauth=22025-04-18 14:58:31,674 - DEBUG - ...
