stm32/boards: Add STM32H750VBT6 board.
Now I have a board based on STM32H750 MCUs.
It has a 64 Mbit external flash.
So now I confused how I can build a firmware for it,it only have 128 kb ROM.
I can't write a bootloader to jump to app because I have poor programming skills.(And I have experienced several compile failure).
So why not provide a new port for STM32H750VBT6?It's so fast.
I did my best,then I post an issue here to ask for help.
(And there is something wrong with my msys2...why my Python cannot work???)
(Poor English ORZ...)
stm32: Add support for STM32H753xx and the NUCLEO_H753ZI board.
Summary
I have added support for MCU STM32H753xx and its NUCLEO_H753ZI board.
Most configuration files rely on the corresponding files of NUCLEO_H743ZI2 or its predecessor NUCLEO_H743ZI (now obsolete).
The image of my NUCLEO_H753ZI is here: https://github.com/micropython/micropython-media/pull/108 .
Testing
I tested the 3 LEDs, the USER switch, Ethernet, the REPL on the ST-Link UART and on the second USB port, as well as storage including USB MSC access.
