How to build

• Install commons build tools (build-essential, git...) and ARM gcc toolchain

https://learn.adafruit.com/building-circuitpython/linux#install-build-tools-on-ubuntu-2986713-2

• Get micropython sources and build mpy-cross

git clone https://github.com/micropython/micropython.git
cd micropython
git submodule update --init
cd mpy-cross
make -j4
cd ../ports/stm32/boards

• Get folders WeAct_F401CE and WeAct_F401CE from this repo and past it in current directory (micropython/ports/stm32/boards)

• Configure the board variant in mpconfigboard.h

• Go back to micropython/ports/stm32 directory

• Build the desired board

make BOARD=WeAct_F411CE -j
# if the toolchain is not in your PATH
make BOARD=WeAct_F411CE CROSS_COMPILE=/path/to/gcc-arm-none-eabi-10-2020-q4-major/bin/arm-none-eabi- -j
