Hacking

This template was derived from the ChibiOS/RT demo project for ARM-Cortex-M7 NUCLEO STM32F746 to facilitate development on Arch linux. As a minimum an ARM compiler is needed. Suggest arm-none-eabi-gcc and arm-none-eabi-newlib.

Base project can be found at ChibiOS/demos/STM32/RT-STM32F746ZG-NUCLEO144

For reference:

# System
Linux ARCH 5.6.15-arch1-1

# Compiler 
arm-none-eabi-gcc 10.1.0-1
arm-none-eabi-newlib 3.3.0-1

# Tools
stlink 1.6.0-1
arm-none-eabi-gdb 9.2-1
openocd 1:0.10.0-3

A sensible set of configurations are provided for vscode. To use them install the c/c++ and cortex-debug extensions.

Included tools

  • tools/c_cpp_properties.py
    Produces IntelliSense .json configuration from make output. PYTHON2 script. Adding a new module under source will generally require the paths to be reconfigured:

    $ make clean
$ make | python2 tools/c_cpp_properties.py -C \
  arm-none-eabi-gcc > .vscode/c_cpp_properties.json

  • tools/flashme.sh
    Flashes mcu using st-flash.

  • tools/ttyme.sh
    Launch minicom serial terminal. Edit to reflect your setup.
