Hello community, how are u?Hope everyone is well and safe =)I'm developing an application using SBSFU. While testing the examples (withoout provisioning a AESKEY, only flashing SBSFU engine) i could always return my microcontroller to factory, just c...
Hello, i have have included the stm32g4xx_hal_cryp.c v1.4.0.The clock is for AES is started (__HAL_RCC_AES_CLK_ENABLE)But the AES Registers are always 0, even writting with a debugger is not possible.Do you have any advice ?With friendly regardsMark ...
For some reason, when I enable CRS Automatic Trimming my USB connection gets unstable. I need to unplug/plug back the USB several times for the PC to recognize the device. When I disable the Automatic Trimming mode and use the default HSI48Calibratio...
Hello, Is below problem very common for this STM32F072VBH6 MCU? Parts were not blank and have already been programmed we are not able to program parts with our programmersParts bought from online distributor
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 ...
