hi i am trying to work with ST given example code of SBSFU for the U585 controller. Here my requirement is to add the active tampers to the system. in this given code i think tamper is only configured in the bootloader application only.tamper detecti...
Hi,Currently I can able to RDP protection ie., Product state using STM32CubeProgrammer and it is working.But our requirement is we want to use Any HAL_driver /C-code instead of STM32Cube. Any suggestion.
Hi @Jocelyn RICARD, My team developed Android app with following code to encrypt the message then send it to STM32WB55 device via BLE : ... SecretKeySpec secretKeySpec = new SecretKeySpec(secretKey, "AES"); IvParameterSpec parameterSpec = new IvParam...
Hi,I want to use SBSFU with my simple application. I watched https://youtube.com/playlist?list=PLnMKNibPkDnGd7J7fV7tr-4xIBwkNfD--&si=T2hYVP2BWDyQkhAWI successfully implement the SBSFU example project on my board. Here, I've a problem to use SBSFU wit...
Hi all,I'm new to using the STM secure boot/secure firmware update and I'm trying to understand how the verification works when sending a new firmware image to the board. I got SBSFU running on an STM32H750B-DK dev board and successfully loaded the e...
HI,we are interested in a guide to a clear workflow of integrating CubeMX-generated code for U5 into TFM-based application.In particular:1. We have trustzone-enabled CubeMX-generated app with Azure RTOS and TouchGFX. The IDE and compiler are IAR. We...
Hello everyone,I am currently debugging a Cortex-M33 MCU with TrustZone-M. During my debugging session, I have observed some unexpected behavior when reading the VTOR (Vector Table Offset Register) in both secure and non-secure states using GDB.Backg...
Hi, I am currently working on migrating a project from STM32 Crypto Library version 3.1.5 to version 4.2.1. I would greatly appreciate your assistance with the following queries:Compatibility Inquiry: Is version 4.2.1 compatible with version 3.1.5? S...
Hi, I am working on integrating the TPM ST33TPHF2XI2C into our platforms and we noticed that there are two GPIOs in the TPM chip. The datasheet says the following: The GPIO function could be modified by activating GPIOs mapped on the NV storage inde...
We are developing a Matter device using X-CUBE-MATTER.How can I make the sample firmware using SBSFU into a sleepy end device? Just setting CFG_FULL_LOW_POWER to 1 fails the commissioning. How can I enable Sleep Mode like the generic-switch app?The d...
