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 using stm32h563zi microcontroller (Nucleo-H563zi) in this i have created project using trust zone. In this aim was to use UART4 to transmit message. But i am unable to transmit, i have uploaded main.c of secure and nonsecure. what is the possib...
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...
Dear ST,For the implementation of many security mechanisms (e.g., the MARCH C algorithm), the use of a RAM backup buffer is proposed. However, I can't find a RAM backup buffer in the STM32G0 family datasheet. I also can't find the SRAM Backup option ...
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...
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...
