Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
When using TrustZone, the memory address changes from 0x0800 0000 to 0x0c00 0000. Is thr actual physical address the same? Or are the memory regions separated into a 0x0800 0000 region and a 0x0c00 0000 region? Using MCU stm32l562 freeRTOS
Hi all,I am looking into secure bootloader options for the STM32U5G9J-DK2 that support application updates using TF-M,please give me guide lines to achieve secure bootloader.
Hi,I have generated a CubeMX project with trustzone. So, I have a secure and a nonsecure project. The secure project runs, jumps to the nonsecure project and the nonsecure project tries to blink the red. I am using CMakeLists and have included my_app...
We appreciate the example in the STM32Cube repository, located at STM32Cube_FW_H5_V1.1.1\Projects\NUCLEO\H563ZI\Examples\FLASH\FLASH_OBK_EraseProgram. We are looking to modify the product state and write the .obk file directly from the firmware, and ...
Hello ST Community,I am working with an STM32U5 based board and facing serious issue related to RDP Level 2 and debug access. I am attempting to recover the device using STM32 Programmer CLI and Cube Programmer but it is not responding as expected e...
Moved from this thread.Any method to implement X-CUBE-CRYPTOLIB in a project ?
I am working through this course but am stuck because the new 2.0.0 version of SM no longer provides the batch files like provisioning_auto.bat that are referenced in the course and I am unsure how to continue.Also posted this on the course page at h...
We attempted to change the product state to "Closed" on STM32H523, and this operation was successful. We can perform a full regression to the "Open" state. However, we are experiencing unexpected behaviour during the provisioning stage. The code in t...
Hi, I am working on the STM32H533RE microcontroller and implementing AES-CCM encryption using a NIST test vector for validation. While the encrypted output matches the expected result, the authentication tag generated is incorrect. I have shared the ...
Hello! I would have an app that is divided between a secure part and a non secure part. The memory definition is as following in the secure linker script: /* Memories definition */ MEMORY { RAM (xrw) : ORIGIN = 0x30000000, LENGTH = 320K FLASH (rx) : ...
