# micropython-raspberrypi

MicroPython on bare metal Raspberry Pi Zero / Zero W / 2

## How to build

```

git clone https://github.com/boochow/micropython-raspberrypi.git

cd micropython-raspberrypi

git submodule update --init

cd micropython; git submodule update --init; cd ..

cd raspberrypi

```

for Raspberry Pi Zero/Zero W,

```

make BOARD=RPI1

```

for Raspberry Pi 2

```

make BOARD=RPI2

```

## Options

1. `MICROPY_HW_USBHOST=1` to enable USB keyboard support.

1. `MICROPY_MOUNT_SD_CARD=1` to mount SD card on /sd in the boot sequence(default).

## How to install

1. download `bootcode.bin` and `start.elf` from https://github.com/raspberrypi/firmware/tree/master/boot

1. copy `bootcode.bin` and `start.elf` to the root of your microSD card

1. copy `build/firmware.img` to the root of your microSD card

1. copy build/config.txt to the root of your microSD card. (if `config.txt` already exists, edit it to add a line `kernel=firmware.img`.)
