Hello all,In both files sfu_kms.h and sfu_interface_crypto_scheme.h there is a header guard called SFU_KMS_H.sfu_kms.h:sfu_interface_crypto_scheme.h:Is that a bug or intentional decision?
Hello,I have not been able to debug any of my TrustZone projects. In order to see what was happening I decided to debug and run ST examples, also with TrustZone implemented, from "STM32Cube_FW_L5_V1.5.0" with the following results:- FreeRTOS_Secure_I...
It seems to be a recurring challenge in the community posts of getting firmware MPU configuration to work with SBSFU. We also had the problem of application firmware hanging when running it with SBSFU. A solution of clearing floating point unit flags...
How to exit safe mode when the security position of the chip is 1 and the protection area of the flash of the new chip is from 0x080000000 to 0x082020000, but the content in the flash is erased，Thank you.
Can the internal TRNG peripheral of the STM32U5MCU be accessed on the STM32U575I-EV eval board?
Hi all,In our project we have enabled the ENABLE_IMAGE_STATE_HANDLING flag and download an image via YMODEM transfer to our NUCLEO-L476RG. However, when we try to validate the image by calling SE_APP_ValidateFw(), our STM reboots and does a rollback....
Hello all,I've encountered an issue while porting 2_Images_KMS B-L4S5I-IOT01 project onto STM32F756ZGTxx.My build fails while compiling nvms_low_level.c file:Source of the issue is FLASH driver for STM32F7, which is different from STM32L4. Do you hav...
I am trying to follow the getting started guide (UM2262) for the SBSFU using our own hardware. I have got as far getting to the main "secure boot and secure firmware update" screen in Tera Term, however when trying to send the .sfb file, I get the f...
hello:as mentions on title,my target board is NUCLEO-C031C6. and I change the read protection level of flash from 0 to 1(0xAA to 0xBB) by STM32CubeProgrammer.after that, the target board can not be connect any more.(keil c/ cubeMX/ cubeProgrammer/ ST...
Hi,I am trying to integrate custom user application with SBSFU bootloader for p-nucleo-WB55 and I was wondering in case anyone saw the following issue.When I try to use the Secure Engine functions for validation in my user application, the program g...
