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.
