Initialize submodules – this pulls in MicroPython, among others. (Don't use
--recursive, MicroPython has a lot of submodules and most are not needed!)git submodule update --init
-
Initialize the required ones among MicroPython’s submodules.
make -f micropython_embed.mk submodules
-
Build the embed port of MicroPython, including
mpy-cross.make -f micropython_embed.mk
