• Correction the memory settings according to STM32H723
• New board specific files related to pinout
• Added the board specific configuration in targets.json file
• MCU page with Wio-H725AE details (more in section Documentation bellow)
• Upload method configuration for this target

Impact of changes

[x] Tests / results supplied as part of this PR

I made Greentea test and two test failed. However I found it is related to the whole STM32 or just the H7 family and not just this board specifically. For more see https://github.com/mbed-ce/mbed-os/wiki/MCU-Info-Page:-STM32H725xE#known-issues

Reviewers

@JojoS62, @multiplemonomials - I do not understand memory settings (linker scripts) so please, be so kind and check mainly that. It is just copy of STM32H723.

At the moment I’m handicapped and can not help with the review. I have also ordered this target but still waiting for delivery.
The linker file should work, but for MCUs with complex bus/memory structures, it is hard to have one that fits all. The good thing is, Mbed-CE can have application specific linker files.

[JohnK1987]

Thank you for the info Jojo.
Yeah, I understand and I hope I will be able to modify linker script for external memories in the future (I need to learn something more about that), but for now I am glad for basic functionality.
