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,We are going for mass production of our device and we are using STM32H563IIK6 chip. And We need JTAG need to be Locked.And in our production we are using Segger JLINK .Can you provide how to implement PRODUCT_STATE using Segger JLINK.
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...
Hi everyone!In our project for stm32f446, we are trying to use X-CUBE-CRYPTOLIB to verify the firmware signature on the device using ED25519. Unfortunately, when trying to call the cmox_eddsa_verify method, we get the CMOX_ECC_ERR_MEMORY_FAIL error. ...
I spend a lot of time looking and never could find an easy way to do this. I came up with a solution and thought I would post it.I am using the STM32F407. The F4 series only has one way of calculating the CRC in hardware and that is what I chose to...
