I am using X-CUBE-MATTER v1.1.1. I understand that it is possible to use the DAC and PAI provided by CommScope using the project STM_provisioning. Please tell me more about STM_provisioning. Also, please tell me how to create STM_provisioning in ligh...
Hi Team, I am working on project where we are implementing Secure upgrade feature using SBSFU package, we followed the steps as mentioned by ST community and to integrate SBSFU in our project. we have two modes Debug mode and Release mode.in Debug Mo...
Hi,I am Working on SBSFU. I have Flashed the STM32H753zi example code after flashing i am not able to flash from programmer. even after changing the option bytes RDP level 0 is set.I have Connect another working board of stm32h753zi board i compared ...
Hello.If i set the product state to CLOSED (0x72) without TZ-enabled (TZEN: 0xC3),i can't access the device and the OBK-Keystore from outside.But if i write a user program, i can read the whole OBK-Keystore at:FLASH_OBK_BASE_S + 0x0100;So perhaps it...
Hi, I am working on OEMiROT bootloader for STM32H523. I have copied big parts of the ST OEMiROT example project from H533 example as this is the closest MCU to H523 from the flash memory layout perspectives. However, it is taking ridiculously too lon...
Hello everyone,I've spent a considerable amount of time trying to change the default AES and ECDSA (ECCKEY1) keys, but I can't figure out why it always results in a 'Fw header authentication error' during the firmware image update process.The project...
Hi, There is a lot of differing documentation w.r.t the use of mbedTLS for STM32U5 MUC. Can someone share an "Application Note" or any documentation which explains the integration of mbedTLS library in the project. PS: The relevant configuration file...
I have implemented AES encryption / decryption on a STM32WB55 using keys stored in FUS. However, I'm running into a problem when I try to encrypt or decrypt using a non-FUS key. I get a hardfault when the key is written to the registers. Which I assu...
We have a project where we're using a U5A5 MCU with trustzone enabled and we're currently trying to figure out how to flash without having to use the SAM card. I downloaded the example from ST and am trying to run through the B-U585I-IOT02A TFM exam...
Hi,I've tested freertos when trustzone is enabled, the freeRTOS can work.I've tested PSA API in "TFM_Appli\NonSecure" when freertos not used, also can work.When I try to access PSA API in "TFM_Appli\NonSecure", when freertos is used, it will trigger ...
