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.
