Hi All,I am following the UM2262 document. I will add a screenshot. I enabled the ENABLE_IMAGE_STATE_HANDLING flag to enable rollback, but after updating UserApp.bin, the device continues to reset. I will add a debug log screenshot (it’s not jumping ...
Hi, I'm trying to adapt the SBSFU-Cube repository example for the B-U585I-IOT02A (STM32CubeU5\Projects\B-U585I-IOT02A\Applications\SBSFU, repository V1.7.0) to a custom PCB with STM32U585CITx. Since I don't have access to UART1 I changed it in com.h ...
Hello,(previous post was marked as spam - I don't know why, so I'm posting again...)I've been working on Provisioning my STM32H563 and after 3 weeks of not touching it, I am unable to perform Full Regression or Debug Authentication on my password-pro...
Hi everybody!We have to implement firmware update feature via CAN interface. Our challenge involves implementing a secure and safe firmware update feature via the CAN bus, driven by regulatory requirements in the medical field. Unfortunately, the exa...
Hi All,I am new to SBSFU. I have gone through x-cube-sbfu getting started document in that document provide for UART- based example. can it be implemented with FD/CAN Protocol.Regards,Devank_J
I am looking on how to encrypt my OBKey data using HUK during provisioning.HUK is device specific then how can we give this HUK Key to Trusted package creator to download the OBKey data?
Hello,I am developing with an L4 series MCU.If there is a program in the MCU and the read protection flag is not active (Level 0), when I load a program that activates the read protection flag (Level 1), there is no problem if I cut the power from th...
Hello,I want to use the security features included in the TFM in my application, I have followed UM2851, now,I have a better understanding for TFM and I succeed to implement it in STM32U585, to go further I want ot implement my own non-secure applica...
Hi,I am evaluating/learning the SBSFU application example on STM32WBA55CG and having issues getting it up and running. Below is the screenshot of the example log:To begin with, I want to be able to do the following.1. Flash the bootloader and flash t...
I'm trying to find out the exact steps to regress an STM32U083 to an erased state after programming it with the OEMiRoT example project and and locking it to RDP2 by the accompanying provisioning.bat script.Will be using STM32CubeProgrammerCLI (or th...
