Hello ST Community,I'm currently working on a project using the STM32WB55 MCU and am in the process of implementing Secure Boot and Secure Firmware Update (SBSFU) in my custom application. As part of this, I decided to test the existing 1_Image_SBSFU...
Pls suggest us possible controller for our below requirement : My Controller ..expectation : CANTwo-uart Signed bootSslCypher - like i read in esp32 documentation, is it just software thing, can we use it for all STM controllers ? Secure boot - a...
I have followed a tutorial (https://www.youtube.com/watch?v=i10X4Blr8ns&ab_channel=STMicroelectronics) to try and get a simple BLE application running and view this application using ST's BLE Toolbox on my Android phone. However, I do not see my devi...
Hey guys, how are you?It's been a long time that i'm facing a issue with STM32WB CPU2, most of the times i just fix it without really knowing the cause of it. Basically what happens is after power-up CPU2 simply won't initialize on the first try. I h...
Hello guys, how are you?Currently i have an interesting problem happening with my STM32WB5M. I have a project that uses SBSFU alongside with a firmware that uses the BLE peripheral with CPU2 and etc. I don't use the BLE loader, i developed i customiz...
Hi,I am currently working on a bluetooth application, on an STM32WB55 microcontroller, to which I have integrated OTA update functionality.As Loader I used the one present in the provided code examples.The application and downloads work properly, my ...
I see that those keys are hardcoded in the code. As I understand they are responsible to LTK and CSRK.Should I change ERK and IRK between devices , so they are not the same? Asking for security reasons.
Hello guys,I've implemented SBSFU along side with an USB standalone loader for my project using a STM32WB. My question is, should i implement hardware semaphores and shci_notification for CPU2 during flash erasing and writing operations on my USB ext...
