[#fpackman]_ + +* `XCode <http://developer.apple.com/technologies/xcode.html>`_: + Provides compilers and other basic tools of the trade. XCode was + once free of charge, but Apple has since begun charging for it. If + you'd rather not pay, you can probably get by with just a `make + <http://www.gnu.org/software/make/>`_ binary, but you're on your + own. + +* `Git`_: All of our code is tracked by a distributed versioning + system called Git. A `Mac installer + <http://code.google.com/p/git-osx-installer/downloads/list?can=3>`_ + is available. + +* `dfu-util`_: A tool from `OpenMoko`_ that we use to upload programs + to the Maple over USB. + + .. warning:: Due to firmware bugs in our :ref:`bootloader + <bootloader>`, you must use recent versions of ``dfu-util``, or + uploads will not work. ``dfu-util`` versions 0.6 and greater + should work. + + If you prefer to compile from source, OpenMoko provides instructions + for `building dfu-util on OS X + <http://wiki.openmoko.org/wiki/Dfu-util#Mac>`_. + + If you're in a hurry, you can use the dfu-util binary bundled with + `OpenMoko Flasher + <http://www.handheld-linux.com/wiki.php?page=OpenMoko%20Flasher>`_. To + do this, first `download OpenMoko Flasher + <http://projects.goldelico.com/p/omflasher/downloads/>`_, then move + it to your :file:`/Applications` folder (or wherever you + like). Let's say you save it as :file:`/Applications/OpenMoko + Flasher.app`. Then the ``dfu-util`` binary resides in + + :file:`/Applications/OpenMoko Flasher.app/Contents/Mac OS/dfu-util` + + To run it from the command line, make a symbolic link to the binary + from some place on your ``PATH``:: + + $ ln -s /Applications/OpenMoko\ Flasher.app/Contents/Mac\ OS/dfu-util \ + /somewhere/on/your/PATH/dfu-util + + .. note:: + + Copying the binary won't work, as it relies on dynamically linked + libraries found elsewhere in the .app bundle. + + To make sure this worked, plug in your Maple, put it into + :ref:`perpetual bootloader mode + <troubleshooting-perpetual-bootloader>` (press RESET, then quickly + press and hold BUT for several seconds), and run :: + + $ dfu-util -l + + The output should look like this:: + + Found DFU: [0x1eaf:0x0003] devnum=0, cfg=0, intf=0, alt=0, name="DFU Program RAM 0x20000C00" + Found DFU: [0x1eaf:0x0003] devnum=0, cfg=0, intf=0, alt=1, name="DFU Program FLASH 0x08005000" + +* `PySerial`_: our reset script (which sends control signals over the + USB-serial connection to restart and enter the bootloader) is + written in Python, and requires the PySerial library.

(These are just +special-purpose versions of :ref:`GCC <arm-gcc>`). + +Let's say you saved these into +:file:`~/Downloads/gcc-arm-none-eabi-latest-osx32.tar.gz`. Then unpack +the archive and tell the shell about its contents with:: + + $ cd ~/Downloads + $ tar -xvf gcc-arm-none-eabi-latest-osx32.tar.gz + $ mv arm ~/libmaple/arm + $ export PATH=$PATH:~/libmaple/arm/bin + +After that's done, update your shell startup script so +:file:`~/libmaple/arm/bin` stays in your ``PATH``. + +So far, so good? +---------------- + +Great! Move on by :ref:`compiling a sample program <toolchain-test>`. + +.. rubric:: Footnotes + +.. [#fpackman] Some of these software packages might be available on + `MacPorts <http://www.macports.org/>`_ or `Homebrew + <http://mxcl.github.com/homebrew/>`_. The author had some bad + experiences with MacPorts a few years ago, though, and hasn't + touched a package manager on OS X since. Your mileage may vary. |
