Hello everyone,
I'm currently working on a project that involves the STM32WL5MOC microcontroller, and I need to implement a firmware update mechanism for it. I have some experience with microcontrollers, but this is my first time handling a firmware update process.
Could anyone provide guidance or share resources on how to implement a firmware update for the STM32WL5MOC? Specifically, I am looking for advice on the following:
- Bootloader Design: How should I design a bootloader that can manage the firmware update process? Any example code or tutorials would be very helpful.
- Update Methods: What are the common methods for performing firmware updates on this microcontroller? Should I consider using OTA (Over-The-Air) updates, or is a wired connection (e.g., USB or UART) more reliable?
- Memory Management: How should I handle memory allocation for the new firmware image while ensuring that the current firmware remains functional during the update process?
- Error Handling: What are the best practices for error handling and rollback mechanisms in case the firmware update fails?
- Security: How can I ensure that the firmware update process is secure to prevent unauthorized updates or tampering?
I appreciate any advice, sample code, or references to relevant documentation or tutorials. Thank you in advance for your help!
Best regards,
