Launchpad Projects

This are simple Launchpad projects to get stuff going. I think it's somewhat difficult to get functional code in the internet, so I want to do my part by creating simple projects using various techniques. These projects are tested on the mspgcc uniarch releases. With this guide and a $4.30 Launchpad, there's no excuse not to try out embedded coding!

Dependencies

To compile the binaries, I assume that mspgcc uniarch is installed. If it's not, check out the last part of this README. It's not trivial.

To install the binaries on the Launchpad I use mspdebug, which is fairly easy to install, and can be found in here. The current working version is 0.18.

For the build system, I use Rake, so you'll need ruby and rake installed. After you have that, you can call rake and the project will compile into the final binary. The cool thing about it is that it automatically checks for all *.c files inside the 'src' folder, so if you want to create your own apps, just add the C files and it'll work. Also when compiling, all the 'src' subfolders are added to the header includes, so you can just '#include "path/to/anywhere.h"' and it'll also work. Installation into the Launchpad is as easy as rake install. More info can be found running rake help

MSPGCC 'Uniarch'

Uniarch is an initiative to unify all the work left behind by mspgcc3 and mspgcc4, while also separating the boundaries between the compiler and TI header files. This 'branch' of mspgcc is the most advanced one, having over 300 supported MSP430 devices.

These instructions are highly based on this article with some minor modifications. Just as a side note, this will actually install 2 copies of the tools. One set will be in /usr/local/bin, which will be the tools you'll use everyday (or hopefully frequently enough), and another set will be in /usr/local/msp430/bin which will be the ones called by binutils. You don't need to worry about this set, but don't erase it. More info here.

So, in our home, we will create a workspace to build our binaries

cd
mkdir -p msp430
cd msp430

We will need the following dependencies to build mspgcc. I don't really know which ones are really needed, but with this ones it works, and I'm lazy.

sudo apt-get install patch ncurses-dev build-essential bison flex libgmp3-dev libmpfr-dev libmpc-dev texinfo zlib1g-dev

For some reason, my machine (Ubuntu Server 11.04) didn't recognize mpfr, gmp and mpc, so these are instructions on building them manually, which will install them on /usr/local/

For GMP:

wget ftp://ftp.gmplib.org/pub/gmp-5.0.2/gmp-5.0.2.tar.bz2
tar xvfj gmp-5.0.2.tar.bz2
mkdir gmp
cd gmp
../gmp-5.0.2/configure
make
sudo make install
cd ..

For MPFR:

wget http://www.mpfr.org/mpfr-current/mpfr-3.1.1.tar.bz2
tar xvfj mpfr-3.1.1.tar.bz2
mkdir mpfr
cd mpfr
../mpfr-3.1.1/configure
make
sudo make install
cd ..

For MPC:

wget http://www.multiprecision.org/mpc/download/mpc-0.9.tar.gz
tar xvfz mpc-0.9.tar.gz
mkdir mpv
cd mpv
../mpc-0.9/configure
make
sudo make install
cd ..

After installing those libs, add these lines to your ~/.bashrc file, and then source it. Again, this worked for me, but maybe you won't need it.

#Adding /usr/local/lib to LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

And source it:

source ~/.bashrc

So, now that we have that running, we'll fetch all the latest files from the mspgcc project. As of this writing, the latest release was 20110716, with Long Term Support

wget http://sourceforge.net/projects/mspgcc/files/mspgcc/mspgcc-20110716.tar.bz2
tar xvfj mspgcc-20110716.tar.bz2

Since this release is a LTS version, there will be many patches fixing various bugs. We will now download all the latests patches into a folder called patches

mkdir patches
cd patches

wget http://sourceforge.net/projects/mspgcc/files/Patches/LTS/20110716/msp430-binutils-2.21.1-20110716-sf3143071.patch

Now we will need to download, patch, compile and install the specific versions of binutils, gcc and gdb that will be used in mspgcc. The bin directory will reside in /usr/local/bin for this instructions.

wget http://ftpmirror.gnu.org/binutils/binutils-2.21.1a.tar.bz2
tar xvfj binutils-2.21.1a.tar.bz2
cd binutils-2.21.1
#Bring it to mspgcc
patch -p1 < ../mspgcc-20110716/msp430-binutils-2.21.1-20110716.patch
#Apply all the patches
patch -p1 < ../patches/msp430-binutils-2.21.1-20110716-sf3143071.patch
patch -p1 < ../patches/msp430-binutils-2.21.1-20110716-sf3379341.patch

patch -p1 < ../patches/msp430-binutils-2.21.1-20110716-sf3400750.patch
cd ..
mkdir -p BUILD/binutils
cd BUILD/binutils
../../binutils-2.21.1/configure --target=msp430 --program-prefix="msp430-" --with-mpfr-include=/usr/local/include -with-mpfr-lib=/usr/local/lib --with-gmp-include=/usr/local/include -with-gmp-lib=/usr/local/lib --with-mpc-include=/usr/local/include -with-mpc-lib=/usr/local/lib
make
sudo make install
cd ../..

That should have the mspgcc binutils running. Now to gcc...

wget http://ftpmirror.gnu.org/gcc/gcc-4.5.3/gcc-core-4.5.3.tar.bz2
tar xvfj gcc-core-4.5.3.tar.bz2
cd gcc-4.5.3
#Update to mspgcc

cd ..
mkdir -p BUILD/gcc
cd BUILD/gcc

make
sudo make install
cd ../..

Done with gcc, on to gdb

wget http://ftpmirror.gnu.org/gdb/gdb-7.2a.tar.bz2
tar xvfj gdb-7.2a.tar.bz2
cd gdb-7.2
#Update to mspgcc
patch -p1 < ../mspgcc-20110716/msp430-gdb-7.2-20110103.patch
#No patches for this one
cd ..
mkdir -p BUILD/gdb
cd BUILD/gdb
../../gdb-7.2/configure --target=msp430 --program-prefix="msp430-" --with-mpfr-include=/usr/local/include -with-mpfr-lib=/usr/local/lib --with-gmp-include=/usr/local/include -with-gmp-lib=/usr/local/lib --with-mpc-include=/usr/local/include -with-mpc-lib=/usr/local/lib
make
sudo make install
cd ../..

Perfect, so all that's left is the microcontroller definitions that are part of msp430mcu and libc that is part of msp430-libc. This files are not downloaded yet (they're not inside the mspgcc package downloaded before, just version references which may be outdated)

wget http://sourceforge.net/projects/mspgcc/files/msp430mcu/msp430mcu-20111107.tar.bz2
tar xvfj msp430mcu-20111107.tar.bz2
cd msp430mcu-20111107
sudo MSP430MCU_ROOT=`pwd` ./scripts/install.sh /usr/local/ 
cd ..

Now we need to download, patch, compile and install libc for mspgcc.

wget http://sourceforge.net/projects/mspgcc/files/msp430-libc/msp430-libc-20110612.tar.bz2
tar xvfj msp430-libc-20110612.tar.bz2
cd msp430-libc-20110612
patch -p1 < ../patches/msp430-libc-20110612-sf3387164.patch
patch -p1 < ../patches/msp430-libc-20110612-sf3402836.patch
cd src
make
sudo make PREFIX=/usr/local install
cd ../..

And that's it! You can compile the projects now.

Now, to install mspdebug, follow this instructions

wget http://sourceforge.net/projects/mspdebug/files/mspdebug-0.18.tar.gz
tar xvfz mspdebug-0.18.tar.gz
cd mspdebug-0.18
#make doesn't work for me unless I specify the WITHOUT_READLINE part
make WITHOUT_READLINE=1
sudo make install
cd ..

If your still having problems, maybe this links can help you. (For now there's only one, but as they appear on the interwebs I will post them here) JustinTech

MSPDEBUG USB permissions

Now, having mspdebug installed with the instructions from before, connect your Launchpad to Ubuntu and run mspdebug rf2500. If it doesn't work, don't panic, follow the next steps (based on this article.).

First, as root, add ATTRS{idVendor}=="0451", ATTRS{idProduct}=="f432", MODE="0660", GROUP="plugdev" to /etc/udev/rules.d/71-persistent-msp430.rules. Then run this commands:

sudo addgroup YOUR_USERNAME plugdev
sudo restart udev

Now unplug and replug the Launchpad and try again and it should work.

Something went wrong with that request. Please try again.
