Hi,I ported the SBSFU project to the LoRaWAN_AT_Slave routine, and tested DFU normally and it worked fine, but when I used the wrong file to upgrade, such as readme.txt, the upgrade process ran for a while, and then stopped, showed " Fw header authen...
Hi,I ported example projects from en.x-cube-safea1\project\NUCLEO-L476RG for MbedTLS cryptolib for use on my B-U585I-IOT02A Discovery Kit. The STSAFE-A110 is powered correctly and NRESET is pulled high. It never errors on writes to the device, but al...
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...
