ビルド (2014-09-15) #

Ubuntu 14.04 x64 を使った。 この作業を行う前に、build-essential, git, emacs をインストールしていた。

ソースコードを micropython/micropython · GitHub から取得:

$ git clone https://github.com/micropython/micropython.git
$ cd micropython/stmhal

ビルド……コンパイラが無いので、失敗:

$ make BOARD=STM32F4DISC
Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.
mkdir -p build-STM32F4DISC/genhdr
Create build-STM32F4DISC/pins_qstr.h
CPP ../py/qstrdefs.h
make: arm-none-eabi-gcc: コマンドが見つかりませんでした
make: *** [build-STM32F4DISC/genhdr/qstrdefs.generated.h] エラー 127

コンパイラを調べて、arm-none-eabi-gcc をインストール:

$ apt-cache search ^gcc- | grep eabi

gcc-4.8-arm-linux-gnueabihf-base - GCC - GNU コンパイラコレクション (基本パッケージ)

$ sudo apt-get install gcc-arm-none-eabi

Description-en: Device firmware update (DFU 1.0) USB programmer
 dfu-util is a program that implements the host (PC) side of the USB DFU 1.0
 (Universal Serial Bus Device Firmware Upgrade) protocol.
 .
 Note: At this point only DFU version 1.0 is supported!
 .
 In the OpenMoko project (for example), this program is used to communicate
 with the specially enhanced bootloader u-boot, which implements the DFU
 device side.
