Hello ST,I am using stm32u575 board for secure flash access, When TZEN is enabled i am able read and write to Secure flash(0x0C00 8000), but unable to read/write to non secure area(0x08100 0000). Then I used User Option BytesSECWM1_PSTRT/SECWM1_PEND ...
I am working with the NUCLEO-H563ZI, and I'm trying to write an application that verifies an ECDSA Certificate. I have already successfully done the verification using the HAL_PKA_ECDSAVerif() function provided with all the parameters. My problem is...
Hello,I have implemented most of the functions required for decompressing the public key using the PKA arithmetic functions. But, I'm encountering a timeout error with HAL_PKA_ModExp, even when setting a high delay with HAL_MAX_DELAY. Additionally, t...
Hello,I am implementing Secure Manager V1.2.0 from X-CUBE-SEC-M-H5 in my firmware. I am following the instructions provided in the "How to start with Secure Manager (customized configuration) on STM32H5" page.Is it possible to configure Option Bytes ...
Hi all!I’m starting with secure zone projects using the STM32U575RIT6 microcontroller. First, I want a project with the secure zone active, and that jumps to the non-secure zone to print a message. However, when jumping to the secure zone (NonSecure_...
Hello Team,We are developing a bootloader for STM32H745 MCU. Follwoing are requirements, 1. SDcard will contain the images for M7, M4 and External QSPI flash connected to H745 MCU2. Planning to use Secure boot such as SBSFU. Please suggest if this is...
The STM32U585 chip comes with a pre provisioned device unique public / private key pair which can be used for SFI.Is there a way to be able to work with this key pair outside of SFI for our own custom use case?I know that we can export the device cer...
I have a board with an STM32U575CGTx on it and I am trying to execute a simple Trust Zone Enabled program. I have 2 sample projects attached 1.) Trust Zone Disabled, 2.) Trust Zone Enabled. The project with TZ Disabled runs perfectly, toggling a GP...
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...
