Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
My project uses SBSFU template ported to my STM32L496 board. I need to call the crypto library from the user app. UM2262 mentions cryptographic middleware support in sections 6.2.3 and 6.2.4, but it is vague. Are there other documents that explain b...
Hello,I want to implement my own UserApp (just a blinking LED for the moment but it will implement FreeRTOS and LwIP in future) on Nucleo-H753ZI. I followed Youtube tutorials for SBSFU especially Security Part6 - 04 Experience SBSFU benefits. Then, I...
In SBSFU, bootloader image will be signed? I am using stm32l562e-dk. I want to use SBSFU.1) I Have found the SBSFU example for NUCLEO-L552ZE-Q, but I am not able to find it for stm32l562e-dk. Is it available?2) IN SBSFU when the bootloader is first t...
I have successfully taken the sbsfu sample code and gotten it to work on my hardware. Now, I am trying to adapt my existing application to be SBSFU compatible. Section 8.1 of AN5056 tries to explain this but the examples are all for an .icf linker ...
I am trying to modify the way secure boot handles the reset cause. In the code, I find CHECK STATUS ON RESET function and a comment that reads; "Hence this piece of code must systematically be revisited and tuned for the targeted system." List of a...
I followed the GPIO_IOToggle_TrustZone Example for STM32U5, which is documented in UM2883 (STM32CubeU5GettingStarted.pdf; section 5.1.1). The development board used is a NUCLEO-U575ZI-Q.Details:I've set the TZEN-Bit in FLASH_OPTR using STM32CubeProg ...
Hello.I succeeded to run my own app with SBSFU on a NUCLEO-H753ZI. But now, my app uses Lwip and differents DMAs. Then, I need these 3 MPU regions:MPU_InitStruct.Enable = MPU_REGION_ENABLE; MPU_InitStruct.Number = MPU_REGION_NUMBER0; MPU_InitStru...
Does anyone know if there is a bootloader template available for ATM32H7B3 that I can start off my project with? Preferably some template that allows secure and non secure creation of the bootloader. TIA.
I just start a project to connect STM32H7 device to AWS IoT using STSAFE-A110 , and I am not doing the secure booting.I have couple of questions1) STSAFE-A110 has a ST CA certificates in in zone 1, so my understanding is to retrieve this certificate ...
Hi.,Because i wanted to verify if the processes worked as well on my work provided Laptop. I ran the homework a second time. The TFM Homework of course resulted in mutliple Errors and nothing worked. But now i can't even use the L5 Board anymore. I g...
