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 example before integrating it into my application. However, I'm encountering some issues and would appreciate your guidance.
Issues Encountered:
Application Not Working:
- The bootloader appears to be functioning correctly. I can see the STM_OTA device in the ST BLE sensor mobile application.
- When attempting to perform an OTA update using the my application file, it results in an error.
- Conversely, using the UserApp.sfb file for OTA update works and presents multiple test options (as shown in the attached images).
STM32WB Board Access Issue:
- After these attempts, I'm now unable to access my STM32WB board via ST-Link for flashing and debugging purposes.
Can anyone provide a step-by-step guide on how to properly test this firmware? Are there any specific configurations or steps that I might be missing?
What steps should I take to regain access to my STM32WB board via ST-Link for further debugging?
Any help or suggestions would be greatly appreciated. Thank you in advance for your support!
Best regards,
SJain
