Uses the TivaWare library from TI:

SW-TM4C: TivaWare for C Series Software (Complete), 2.1.2.111

How to set up the system:

Needed:

1. ARM cross compiler (arm-none-eabi-***)
2. TI's Tivaware
3. OpenOCD or 'https://github.com/utzig/lm4tools to flash the device'

Check this and investigate this further: https://github.com/szczys/tiva-c-launchpad-template 'TI has a restrictive license on all of their example files. Becuase of this you cannot use their Makefiles, Linker scripts, or Startup code in open source repositories. This template gets around this issue by creating symbolic links to these files. You need the TivaWare package for libraries anyway, this simply creates links to the pertinent files at compile time.'

Some straight instructions: 'http://www.strainu.ro/programming/embedded/programming-for-the-tiva-c-launchpad-on-linux/'

1. Get ARM GCC toolchain: '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

2. TivaWare: Google SW-TM4C: TivaWare for C Series Software

   mkdir TivaWare unzip SW-TM4C-2.1.0.12573.exe make

Directory structure: . |-> tiva-c-projects |-> TivaWare

3. So far I'm using lm4tools, not OpenOCD

   git clone https://github.com/utzig/lm4tools.git cd lm4tools/lm4flash make sudo make install

   echo 'ATTRS{idVendor}=="1cbe", ATTRS{idProduct}=="00fd", GROUP="users", MODE="0660"' |
   sudo tee /etc/udev/rules.d/99-stellaris-launchpad.rules

Tivaware BUG regarding USB ring buffer. Fix on file: usblib/usbbuffer.c
