Need Guidance on Migrating SBSFU with IOC File to STM32H733VGT6 MCU
I’ve successfully compiled the SBSFU (Secure Boot Secure Firmware Update) code for the STM32H753ZI and updated the firmware. Now, I would like to use it with the STM32H733VGT6 MCU.Previously, I was using the STM32H753ZI controller, which did not util...
Resolved! SFU with 256-bit AES key
Hello,I am having some trouble understanding what bootloader (if any) is installed by ST from the factory for the STM32U5x and what AES key sizes that bootloader supports for secure firmware update. UM2851 only lists AES-CTR-128 (I interpret 128 to b...
STM32H743 - Does RDP protection gives 128 bit flash protection?
STM32H743 - Does RDP protection gives 128 bit flash protection?How to configure for 128 bit.We want to implement read and write protection on the internal flash of the MCU/MPU to avoid unauthorized access through debug ports.
Bootloader and Firmware signing on STM32L452RE
I am using STM32L452RE for an application.I want to implement firmware signing feature on the board so only authenticated firmware is allowed by bootloader to flash on the board. Can i conclude that mbedtls library is popular, but it cannot be used o...
Resolved! STM32U585: AES GCM Tag mismatch
Good afternoon,we are facing issue with AES GCM Tag generated with STM32U585.In particular we compare the results generated by the microcontroller with the ones generated by an application developed with C#.This is the code running on the microcontro...
STM32F030F4P6 option byte programming
Can recognize the chip, but can not burn and read the flash problem. In this case, is the chip broken or the chip locked? There is also a case that the chip can be identified as burning, but it cannot run the normal working program
External Flash Loader with Secure Flash
In my project, I intend to use an external serial flash to hold UI assets as recommended by TouchGFX.I have followed this: https://community.st.com/t5/stm32-mcus/how-to-implement-and-use-your-own-external-flash-loader-an/ta-p/597752 but I only get fl...
Resolved! Can OTFDEC be used regardless of OCTOSPI modes and interfaces?
We are planning to use an external flash memory connected via QuadSPI to the OCTOSPI peripheral of a STM32H735 (at a later stage that would be STM32H733).This will be used to run firmware and store downloaded firmware updates with SBSFU. For that we ...
Resolved! STM32U5 - SBSFU
Good Morning,I am working on the Secure Boot using STM32U5 with this repository : https://github.com/STMicroelectronics/STM32CubeU5/tree/main/Projects/B-U585I-IOT02A/Applications/SBSFUI am trying to add a kind of "Dev. Mode" which authorise the boot ...
