Unix Toolchain Linux Setup
==========================
This page contains instructions for setting up a Linux computer for
use with the :ref:`Unix toolchain <unix-toolchain>`. (Setup
instructions for :ref:`other operating systems <toolchain-setup>` are
also available.)
These instructions have been tested successfully on:
- Ubuntu 10.04 and 12.04 (32- and 64-bit)
- Fedora 17 (64-bit)
- Debian Wheezy 64-bit
Generic instructions for other distributions are also provided. Please
`contact`_ us with any updates for distros not already covered!
.. contents:: Contents
:local:
Collect and Install Tools
-------------------------
First, you'll need some tools.
.. 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.
**Debian-based distributions (Debian, Ubuntu, Mint, etc.)**:
Install mandatory and optional tools with ::
$ sudo apt-get install build-essential git-core screen dfu-util python python-serial
On *64-bit distros only*, you will also need to install some 32-bit
libraries needed by the LeafLabs-supported :ref:`ARM GCC toolchain
<arm-gcc>` with ::
# 64-bit systems only!
$ sudo apt-get install ia32-libs
You may also need to remove `brltty <http://mielke.cc/brltty/>`_
with ::
# Optional
$ sudo apt-get remove brltty
Brltty provides braille access to the console. It has been reported
to cause conflicts with Maple.
**Red Hat-based distributions (RHEL, Fedora, Centos, etc.)**:
Install mandatory and optional tools with ::
$ sudo yum install screen git python pyserial dfu-util make
On *64-bit distros only*, you will also need to install 32-bit
libraries needed by the LeafLabs-supported :ref:`ARM GCC toolchain
<arm-gcc>` with ::
# 64-bit systems only!
$ sudo yum install glibc.i686
You may also need to remove `brltty <http://mielke.cc/brltty/>`_
with one of these::
# Optional, 64-bit systems:
$ sudo yum erase brltty.x86_64
# Optional, 32-bit systems:
$ sudo yum erase brltty.i686
Brltty provides braille access to the console. It has been
reported to cause conflicts with Maple.
**Other Linux distributions**:
On other distributions, you'll need to figure this out for yourself
(please `contact`_ us if you have instructions for distros not
covered here!).
Mandatory tools:
* `Git`_ is a distributed version control system. We use it to track
our source code.
* `dfu-util`_ is a tool from the `OpenMoko`_ project. It is used to
upload programs to the Maple over USB.
* `Make <http://www.gnu.org/software/make/>`_ is used to direct
compilation.
* `Python`_ is a programming language. Our reset script, which sends
control signals to the board which cause it to to reset and enter
the :ref:`bootloader <bootloader>`, is written in Python (and
works with Python 2 or 3). Most Linux distributions these days
include Python by default.
* `PySerial`_ is a Python library for interacting with serial port
devices. It's needed by our reset script. PySerial can also be
installed with `easy_install`_.
Optional tools:
* `screen <http://www.gnu.org/s/screen/>`_ is a screen manager used
here to connect to serial port devices. (Some popular
alternatives are `Minicom
<http://alioth.debian.org/projects/minicom/>`_ and `Kermit
<http://www.kermitproject.org/>`_).
Fetch ``libmaple`` and Compiler Toolchain
-----------------------------------------
First, make a Git clone of :ref:`libmaple`::
$ cd ~
$ git clone git://github.com/leaflabs/libmaple.git libmaple
Next, download the `Linux ARM GCC toolchain
<http://static.leaflabs.com/pub/codesourcery/gcc-arm-none-eabi-latest-linux32.tar.gz>`_
you'll use to build your programs. Extract the archive into a
directory named :file:`arm`. Put the resulting :file:`arm/bin`
subdirectory somewhere in your ``PATH``. For example, if you have
`wget <http://www.gnu.org/software/wget/>`_ installed, you can run::
$ cd ~/libmaple
$ wget http://static.leaflabs.com/pub/codesourcery/gcc-arm-none-eabi-latest-linux32.tar.gz
$ tar xvf gcc-arm-none-eabi-latest-linux32.tar.gz
$ export PATH=$PATH:~/libmaple/arm/bin
You can check that this worked by entering ``arm-none-`` and hitting
tab to auto-complete; your shell should show a bunch of results. After
you're done, you'll probably want to update your shell startup script
so the :file:`arm/bin` directory stays in your ``PATH``.
.. _toolchain-udev:
Install udev Rules
------------------
From the libmaple directory, copy our udev rules [#fudev]_ to
``/etc/udev/rules.d``::
$ sudo cp support/scripts/45-maple.rules /etc/udev/rules.d/45-maple.rules
Then restart udev.
**Ubuntu (NOT Debian)**:
Make sure you are in the plugdev group (e.g. by running ``$ groups``
and seeing if the output includes "plugdev"). If not, add yourself
to plugdev with ::
$ sudo usermod -a -G plugdev $USER
then log out and log back in.
After that's done, restart udev::
$ sudo restart udev
**Debian (NOT Ubuntu)**:
Make sure you're in the dialout group. If not, add yourself with ::
$ sudo usermod -a -G dialout $USER
then log out and log back in.
After that's done, restart udev::
$ sudo /etc/init.d/udev restart
**Red Hat-based distros**:
::
$ udevadm control --reload-rules
After restarting ``udev``, you'll need to unplug and re-plug your
Maple.
So far, so good?
----------------
Great! Move on by :ref:`compiling a sample program <toolchain-test>`.
.. rubric:: Footnotes
.. [#fudev] As a security precaution on Linux, unknown USB devices can
only be accessed by root. This udev script identifies the Maple
based on its vendor and product IDs, mounts it to
:file:`/dev/maple`, and (for Debian-based distros) grants
read/write permissions to the ``plugdev`` group.
