Nucleo STM32H743

[hakanlundvall]

There is currently support for STM32H723 in rustBoot. I have a Nucleo STM32H743 evaluation board that I want to add support for it but I'm new to both rust and stm32 mcu's. I would appreciate some pointers on where to start and what parts of the existing H723 implementation that likely needs changes.

@imrank03 - maybe this is something you can help with

@hakanlundvall - just a quick note in case you didn't know. We have a matrix channel for rustBoot. The link to the channel is on the README page.

Hello @hakanlundvall, here are some general pointers to get you started:

• Clone the Repository:

  • Begin by cloning the rustBoot repository to your local development environment.

• Develop Flash Driver and Create Partitions:

  • Write a flash driver for the STM32H743, making necessary adjustments. Additionally, create partitions as needed. Note that the existing flash driver for the STM32H723 can serve as a reference due to the similarities.

• Compare Datasheets:

  • Conduct a detailed comparison between the datasheets of STM32H723 and STM32H743. Identify both the similarities and differences between the two microcontrollers.

• Review and Modify Peripheral Drivers:

  • Examine the existing peripheral drivers for the STM32H723 and make required modifications for the STM32H743. This involves updating register addresses, interrupt handling, and other hardware-specific details.

• Consult rustBoot Documentation:

  • Refer to the rustBoot documentation for guidance throughout the adaptation process.

If you have any questions or queries during the development process, feel free to ask.

Thanks, I have it running now. So far I have just made changes to the H723 example until it ran on H743. I'll try to clean it up and add it as a separate board alongside the H723, when I have time.
