br_platformio_hwdef

PlatformIO platform (br-stm32) providing board definitions, variants, linker scripts, and bundled bootloader binaries for Beyond Robotix STM32 hardware.

Supported boards

Board	MCU	Clock	Flash
MicroNode	STM32L431	80 MHz	256 KB
CoreNode	STM32H743	480 MHz	2 MB
MicroNodePlus	STM32H723	550 MHz	1 MB

Usage

Reference the platform from your platformio.ini. PlatformIO downloads it on first build — nothing to install.

[env:my-env]
platform = https://github.com/BeyondRobotix/br_platformio_hwdef.git
board = MicroNode       ; or CoreNode, MicroNodePlus
framework = arduino
board_build.ldscript = ldscript.ld

Bootloader-aware envs (two-stage flash)

Any env whose name ends in -Bootloader (and does not contain No-Bootloader) using a bare ldscript automatically gets a two-stage flash on pio run -t upload: first the bundled variants/<board>/bootloader.bin at 0x08000000, then the compiled app at the board's app-start address. No extra_scripts entry needed.

[env:Micro-Node-App]
platform = https://github.com/BeyondRobotix/br_platformio_hwdef.git
board = MicroNode
framework = arduino
board_build.ldscript = ldscript.ld

Refreshing the cached platform

PlatformIO caches the platform locally after the first fetch. To pick up new changes to this repo:

pio pkg uninstall --platform br-stm32 -g

…or delete the platform directory directly:

• Linux/macOS: ~/.platformio/platforms/br-stm32/
• Windows: %USERPROFILE%\.platformio\platforms\br-stm32\

The next pio run re-fetches from GitHub.
