Hi,I come to you about the key provisioning process for the iROT in the STM32H5.Using TrustedPackageCreator, the keys provided in the file STiROT_Config.xml for the Secure Boot (field <Authentication key>) are both the private and public keys of the ...
Hi, I am working with the SBSFU_Boot on the STM32U5A9 chip. After the SBSFU_Loader has written the update image into internal memory, a reset happens in order for the SBSFU_Boot to write the image to be booted. When performing the update, it ends up ...
HiI am implementing the ECDSA-P256 signing for a payload.I have checked the example code https://github.com/STMicroelectronics/STM32CubeU3/tree/main/Projects/NUCLEO-U385RG-Q/Examples/CCB/CCB_Protected_ECDSA_SignatureThe example code shows that the s...
Device detailsMPU: STM32H753AII6Connection:Probe: J-Link V11.00 / SW version V7.98c STM toolset: STM32 Cube Programmer / Trusted Package Creator v2.20.0SFI programming fails with error:Error: SECURITY State FailError: Invalid state after SFI install ...
HiI am using STM32L562 and sampled and flashed the Zephyr OS example for TrustMode. I could not revert back the TrustZone therefore followed the information from the link https://community.st.com/t5/stm32-mcus-security/reverting-option-byte-configura...
Hello,I'm using STM32F439 with LWIP, SNMPv3, and mbedTLS, without FreeRTOS. I've encountered a performance issue when using the hardware acceleration for AES and SHA1 provided by ST (aes_alt.c, sha1_alt.c).Specifically, when decoding SNMPv3 messages,...
Hi everyone,We’re developing an IoT node for agricultural applications and plan to make it compliant with certification requirements (CE, CRA, RED).We’re using the X-CUBE-AZURE package as our starting point and want to use TF-M (Trusted Firmware-M) f...
I’m working with a NUCLEO-H533RE board (STM32H5 series, TrustZone enabled) and using ST-LINK for debugging.Here is the issue:Debug Authentication succeeds (certificate-based).Immediately after, the tool disconnects and shows:Error: Unable to get core...
Hello STM32 Community,I’ve successfully built a Zephyr RTOS blinky application for the NUCLEO-H533RE board. Flashing the zephyr.hex using west flash or STM32CubeProgrammer works perfectly — the LED blinks and the serial terminal prints the expected s...
Hello,My device contains both a bootloader and an application. I’m currently trying to protect the bootloader using PCROP on the STM32G0B1.As a first approach, I attempted to configure PCROP using STM32CubeProgrammer. However, this failed — once PCR...
