Hello everyone,I'm working with the STM32L562E-DK board and the STM32Cube_FW_L5_V1.5.0 firmware. I want to integrate my own code (which reads a sensor MPU6050 via I2C) into the STM32CubeL5 TFM (Trusted Firmware-M) application, running it in the Non S...
Hello,I am using STM32H750 and X-Cube-Crypto lib. I am working on a secure boot and want to calculate the app Hash value to check integrity. The library works fine for STM32L5 Mcu (Already tested) but not with STM32H750. I verified that I am using th...
Hi, I am working with the SBSFU_Boot on the STM32U5A9 chip. After the SBSFU_Loader has written the update image into internal memory, a reset happens in order for the SBSFU_Boot to write the image to be booted. When performing the update, it ends up ...
Hello,I am following the blog "Implementing Debug Authentication on STM32H5 using CLI tools" (https://community.st.com/t5/stm32-mcus/implementing-debug-authentication-on-stm32h5-using-cli-tools/ta-p/622308) to provision my STM32H533RE based custom bo...
Hi,I am setting up SBSFU on our STM32H750. I want to test the RDP and WRP security protections.Steps taken so far:I have enabled WRP and RDP Level 1 by setting the option bytes through cubeprogrammer and enabling SFU_WRP_PROTECT_ENABLE & SFU_RDP_PROT...
When we provision the Secure Manager on the STM32H5 and there is no non-secure application available (yet), then the Secure-Manager-Demo-Application currently starts flashing all LEDs on the STM32H573I-DK.Now we wonder how this would affect our proje...
Hi,I have a question regarding STiRoT provisioning on the STM32H573.As I understand, during the Secure Boot provisioning process, the public key hash is injected into the OBKeys area of the device to establish the root of trust. However, I would like...
I am trying to understand SMiRoT and SMuRoT for product development based on the STM32H573 and Secure Manager, but from the public documentation they both look mostly like black boxes.Since they seem to be built on top of STiRoT / STuRoT, I am curren...
Hello, I am working with the STM32H745 using a Lauterbach TRACE32 debugger and i am evaluating ways to control Readout Protection (RDP). I am able to configure RDP levels using STM32CubeProgrammer, however I would like to achieve the same using a TR...
Hi,I am trying to create a trustzone application for my board, but suddenly I could no longer flash to non-secure memory. Secure memory flashing still works fine. What am I doing incorrectly?Thank you in advance,Michalthe failing flash (fails even if...
