Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
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...
Hello,I am using X-CUBE SBSFU for an application running on STM32H750 mcu.The user application is running from QSPI, and I want to encrypt/decrypt some data that will be stored into an external EEPROM.To do this I would like to use an AES algorithm a...
Hi, I am working on NUCLEO-H743ZI EVK to test the secure boot using X-CUBE-SBSFU-v2.7.0 package. I have successfully uploaded the boot image at the location 0x8000000 address and i have uploaded the userapp.sbf file using tera-term tool. I have follo...
I am currently facing a critical issue with reading and programming two OBK sectors (current and alternate) from within firmware while using the iCache on the STM32H562. Despite my efforts to disable iCache access to the OBK address range using the M...
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 ...
