Summary

Add support for the DevEbox STM32H743 board based on the STM32H743VI microcontroller (Cortex-M7, 400 MHz).
Board reference: https://stm32-base.org/boards/STM32H743VIT6-STM32H7XX-M

Two commits:

  1. board/devebox-stm32h743: New board devebox-stm32h743 — board files, 3 configurations (nsh, nsh+debug, full), clocking at 400 MHz (optional 480 MHz with over-drive via #define STM32_PLL1_480MHZ).
  2. boards/devebox-stm32h743: add board documentation — RST documentation with pin mappings, flashing instructions, and configuration descriptions.

Board features:

  • USB-C power supply, SWD connector
  • 25 MHz HSE, 32.768 kHz LSE
  • 1 user LED (PA1), 2 buttons (PE3, PC5)
  • USART1 serial console (PA9/PA10)
  • SDMMC1 microSD slot
  • QSPI W25Q64 (8 MB) NOR Flash
  • USB OTG FS

Impact

New board addition only. No impact on existing boards or subsystems.

Testing

All 3 configurations were built and tested on hardware.
Configs:

  • nsh
  • nsh+debug
  • full

Documentation: make html in the Documentation/ directory — build succeeded.
Build host: Linux x86_64, GCC arm-none-eabi
Target: DevEbox STM32H743 (STM32H743VIT6)

@seniorandre please include the board picture

Also could you please keep only "nsh" and "full" board profile? Each board profile requires a new build on NuttX CI and increase the overall test time.

@acassis, Thank you for the review,
I removed sdcard, usbnsh, and w25 configurations (board dirs + docs). I kept nsh+debug because it is important for development — it enables assertions, stack checking, and RAMLOG without the extra features of full, making it the primary config used during board bring-up and debugging.

Sounds good, thank you @seniorandre
