Flashing Firmware
=================
Building firmware
-----------------
Use yotta to build.
Use target bbc-microbit-classic-gcc-nosd::
yt target bbc-microbit-classic-gcc-nosd
Run yotta update to fetch remote assets::
yt up
Start the build with either yotta::
yt build
...or use the Makefile::
make all
The result is a microbit-micropython hex file (i.e. ``microbit-micropython.hex``)
found in the build/bbc-microbit-classic-gcc-nosd/source from the root of the
repository.
The Makefile does some extra preprocessing of the source, which is needed only
if you add new interned strings to ``qstrdefsport.h``. The Makefile also puts
the resulting firmware at build/firmware.hex, and includes some convenience
targets.
