I have exported X509 certificate from STM32H573I-DK board, and checked how it is organised.The certificate was issued by "ST CA 01 for STM32 Initial Attestation".I would like to verify whether it is truely signed by ST's upper-level certificate.Wher...
HelloI am developing on the STM32H7B3-DK using X-CUBE-SBSFU v2.7.0 with IAR compiler version 9.70. During the build, I encountered the following critical error:Fatal error[Li004]: file "STM32CryptographicV3.1.3_CM7_IARv8.a" is not an object or archiv...
Hello,I have already read the AN4758 application note and I still have a few questions regarding PCROP.I have a project for end-users where the main application provides functions (API) that users can call to develop their own code. I was originally ...
Hi,I am using STM32H56x with OEMiROT_Boot example project, currently the swap method of the OEMiROT_Boot is "MCUBOOT_SWAP_USING_SCRATCH", can I change it to MCUBOOT_SWAP_USING_MOVE?Is there any security concern use MCUBOOT_SWAP_USING_MOVE?Regards,Sn...
I've been playing around with the TrustZone Enabled on the STM32H573 board and using this tutorial:https://wiki.st.com/stm32mcu/wiki/Security:How_to_start_with_OEMiRoT_on_STM32H573_and_563%E2%80%93TrustZone_enabledI had no trouble executing the tutor...
Hi ST team,I am using STM32U5G9 in my project. It would need simple firmware update feature and the image would be received by UART from a zigbee module.I have read UM2851 and AN5447 application notes and check the SBSFU example in STM32CubeU5 packag...
Hi,I am using STM32H563 with OEMiROT_Boot example project, I got a problem to read the FLASH_SIZE register (0x08FFF80C).I found two issues,(1) the value of this register is 0 at begining of OEMiROT_Boot main() function.(2) the register become not acc...
I've been struggling with this problem for several hours.Using bare metal, I can invoke a non-secure callable from the non-secure application.When I added FreeRTOS + CMSIS RTOS v2 wrapper, and try to do the same from a thread context, I get a hard fa...
HiI am using STM32L562 and sampled and flashed the Zephyr OS example for TrustMode. I could not revert back the TrustZone therefore followed the information from the link https://community.st.com/t5/stm32-mcus-security/reverting-option-byte-configura...
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 ...
