Hi @Jocelyn RICARD,im trying to enable the secure user memory on my custom bootloader for STM32H755 and STM32H7B3 MCUs.The bootloader is on the first bank and the app on the second bank. The secure user memory is enabled successfully on bank 1 but j...
In current, I am using the NUCLEO-H753ZI of STM32CubeExpansion_SBSFU_V2.7.0 demo project.Hardfault error happens in SFU_SE_STACK_Clean api in case SFU_ISOLATE_SE_WITH_MPU is not used like "#undef SFU_ISOLATE_SE_WITH_MPU"the value of sp is 0.Please le...
Hello,I try to implement a tamper detection for my project. In general, it works. When the device is only powered by a coin cell and a tamper is detected, the backup registers are erased and unfortunately also the backup RAM. When the device is power...
I would like to increase the code readout protection level from 0 to 1 programmatically in an STM32G030. I must be doing something silly and if anyone sees it, I'd be grateful. I've stepped through it with the debugger and the flash and option byte...
Hello,It seems to me that the wiki page: https://wiki.stmicroelectronics.cn/stm32mcu/wiki/Security:Secure_storage-SAES_key_wrapping_for_STM32N6 is unavailable as I get the message: "Page not found".I tried searching for it, to no avail. Is the relate...
Hi,I'm currently developing on the STM32H743ZI microcontroller and have successfully implemented secure boot using the X-CUBE-SBSFU package. Now, I want to update the ECC public key at runtime on the device.While reviewing the Getting Started with th...
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...
