Build instructions
------------------
Before building the firmware for a given board the MicroPython cross-compiler
must be built; it will be used to pre-compile some of the built-in scripts to
bytecode. The cross-compiler is built and run on the host machine, using:
```bash
$ make -C mpy-cross
```
This command should be executed from the root directory of this repository.
All other commands below should be executed from the stmhal/ directory.
An ARM compiler is required for the build, along with the associated binary
utilities. The default compiler is `arm-none-eabi-gcc`, which is available for
Arch Linux via the package `arm-none-eabi-gcc`, for Ubuntu via instructions
