Recenlty I had a major HDD failure and I had to regenerate my working environment on a new HDD. This article contains the step-by-step instructions to set up a working development environment for the Stellaris Launchpad under Linux Ubuntu 12.04 64bit.
Installing the toolchain
The toolchain for ARM is available as a ppa at: https://launchpad.net/gcc-arm-embedded
$ sudo add-apt-repository ppa:terry.guo/gcc-arm-embedded
$ sudo apt-get update && sudo apt-get install gcc-arm-none-eabi
Install Energia IDE
I chose to install a stripped-down version, much smaller that doesn’t contain the compiler tools which I’ve installed independently.
The package is available at: http://fabhack.com/doc/stellaris/energia, choose the 32bit or 64bit version accordingly to your architecture.
$ wget http://fabhack.com/_media/energia-0101e0009-linux-notools-64bit.tar.gz
$ tar -xzvf energia-0101e0009-linux-notools-64bit.tar.gz
$ mv energia-0101e0009 energia
lm4flash is the tool used to flash the Stellaris Launchpad, in order to build it, you need build essentials, and other dev packages:
$ sudo apt-get install libusb-1.0-0-dev pkg-config
$ git clone https://github.com/utzig/lm4tools.git
$ cd lm4tools/lm4flash
Now you can move the built binary to a path where your system can find it, I usually put my binaries in the “bin” folder under my home folder.
You can launch energia from your home folder:
Choose an example sketch (Blink) and try to compile and upload.
