Dear,Is it possible for execution within HDPL_x to use SAES (Secure AES) with a DHUK (Derived Hardware Unique Key) from HDPL_y where x > y?For example:Execution within HDPL2 makes use of SAES to encrypt plaintext p using its DHUK, this results in cip...
Hello Firends,Two Questions...1. Firmware Flash with DFU Bootloader succesfully done along with RDP bit. Can we re-flash the fiirmware once RDP L1 is set before through DFU using USB ? my custom board uses STM32F303Rb device. 2. Each STM32 device has...
I am trying to write a .bat script to reliably flash my combined sbsfu and application binary to a stm32h755. set cube_programmer_cli="C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe" set fw_bin="combine...
Hello everyone, I am working with the STM32H7B3 MCU and evaluating the Secure Boot and Secure Firmware Update (SBSFU) package. My setup uses a dual image slot configuration with the SECBOOT_ECCDSA_WITH_AES128_CBC_SHA256 cryptographic scheme. I would ...
Hello!I a new in this.I have two sets of DA files: for password access and for access via certificate.I've tried to flash a NS-firmware, provision a password.obk, then change Product state to Provisioned/closed. Thas was successful. I can perform a r...
Hi,I am currently facing an issue where TrustZone cannot be disabled on the STM32U545 device with custom hardware.1. [Part Number] STM32U545VET6 on custom hardware2. [Environment] STM32CubeProgrammer 2.20.0 with ST-LINK V2; custom Zephyr application ...
Hello Guys,I tried defining STIROT_ILOADER_DEBUG in the main.h of the iLoader and then i built it and uploaded the Code via script after getting loaded only STiROT Application Logs are are printing but STiROT_iLoader logs are not printing, how can i ...
Greetings, I am using a STM32U585 MCU and I made a custom made code that implements the DFU protocol. I could successfully flash a firmare through .bin file and set the Option Bytes, set RDP level 1 and go back to RDP level 0. What I want to do is to...
Hello,I would like to use the TFM application on STM32CubeIDE for the B-U585I-IOT02A board but I can't find the application anywhere. Any help?
Hi,I'm working on the evalboard of the STM32H563. With a plain project I'm able to activate the memory mapped mode of a plugged nor-flash.If I change the project to have Trustzone activated and divided the application in secure/non-secure part, I'm n...
