Hi there,My STM32H573I-DK demo board is stuck in PROVISIONING state, probably as the result of a failed or aborted provisioning operation. I was doing hand-on training with the How to start with STiRoT on STM32H573 wiki. Now, I cannot regress it to...
Hello,I am using the STM32U575ZIT6 microcontroller and have created a simple TrustZone project where all applications run in the non-secure zone. However, when the program attempts to switch to the non-secure zone, it triggers a hard fault handler er...
Hi folks,I am trying to use the hardware-AES of the STM32WLE5JC, but I get weird results that do not match the expected values. I am comparing my STM-implementation against RadioLib's Crypto which is based on tiny-AES-c and AES-CMAC. RadioLib's imple...
Hello, I have created an encrypted file by openssl-aes256-CFB. in openssl IV length should be 128 bit but in X-CUBE-CRYPTOLIB it is not possible, it cannot set to 128 bit, (HARDFAULT). only i can set 256bit and then received error 0x10003
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...
