Hello STM32 Community,
I hope this message finds you well. I am currently working on a project involving the STM32H747XIH6 microcontroller and facing challenges in creating a standalone bootloader using USB OTG FS.
Here are the details of my setup and the issues I'm encountering:
Microcontroller: STM32H747XIH6 Bootloader Objective: Standalone bootloader using only USB device and no intervention of PC
Aim: To make a single code using internal bootloader which will upgrade to new version using USB device.
Challenges:
- I have been trying to develop a standalone bootloader for the STM32H747XIH6, but I haven't been successful to make it work with the single application memory code using internal bootloader and USB device. Currently I am using 2 separate code as bootloader(which programs the application memory) and Application(where the actual code is executed).
- I am encountering issues to integrate application code with internal bootloader code, and I suspect there might be some configuration settings or code snippets I am missing.
If anyone in the community has experience with creating a standalone bootloader for the STM32H747XIH6, I would greatly appreciate your guidance.
Specifically, I would like assistance with:
- Configuring the bootloader appropriately with application memory.
- Example code snippets or projects that successfully implement a similar setup.
- Any common pitfalls or issues to watch out for when developing such a bootloader.
I have referred to the STM32H7 reference manual and relevant documentation, but a community perspective and shared experiences would be immensely valuable.
Thank you in advance for your time and assistance. I look forward to learning from your expertise and overcoming this challenge together.
