I would like to use the mbedTLS version 2.28.2.v2 on the secure boot for stm32h743ii controller. I have downloaded SBSFU v2.6.2 and Built the secure boot binary on top of the example project from H753 2_images_OSC folder. Secure boot is running the t...
We have one STM32h563zi board on which first We blink the normal led program, After that We perform the Secure Boot by taking the reference from STmicro official website, Secureboot run successfully. We run the regression script .Now the board should...
Hello all.Another question regarding SBSFU, this time 1 image version.When we download new image via YMODEM, when does decryption process happen?1. Is new image first downloaded into active image slot and then decrypted?2. Is new image downloaded and...
Ask this at arm.com, but maybe it is STM32U5 specific:I try run an unprivileged application in secure mode and get a strange behavior:STM32U5 has TZ enabled, all application runs in secure mode.1) LR = 0xffff_fff9, CONTROL = 1 => BX LR increments the...
Hi Community,I'm porting STM32G071 SBSFU to STM32G0B1RE and Customizing UART to USB CDC.I'm using Nucleo-G0B1RE dev kit and STMCubeIde for development.1. I'm able to build, load, run both STM32G071 SBSFU and UserApp without any changes. but when I ch...
Hi,I changed symbol in the properties tab to adapt STM32G0B1xx drivers causing hard fault after loading User App. The hard fault occurs in sbsfu while verifying the user fw signature.can someone help me why fw signature verification failed just chan...
I am using the SBSFU STM32CubeExpansion_SBSFU_V2.6.2 version for my custom board STM32H743VI controller. I have ported the STM32H7B3I-DK project for H743 controller for COM port and changed the crypto scheme to SECBOOT_ECCDSA_WITHOUT_ENCRYPT_SHA256. ...
