You will need an ARM bare-metal toolchain to build code for Tiva targets. You can get a toolchain from the gcc-arm-embedded project that is pre-built for your platform. Extract the package and add the bin folder to your PATH. PATH=$PATH:/opt/gcc-arm-none-eabi-4_8-2014q3/bin

If using 64 bit OS:

sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0

The TivaWare package contains all of the header files and drivers for Tiva parts. Grab the file SW-TM4C-1.1.exe from here and unzip it into a directory then run make to build TivaWare.

mkdir tivaware
cd tivaware
unzip SW-TM4C-1.1.exe
make

Note: for the Tiva Connected Launchpad get SW-EK-TM4C1294XL-2.1.0.12573.exe.

1. Clone the tiva-template repository (or fork it and clone your own repository).

   git clone git@github.com:uctools/tiva-template

2. Modify the Makefile:

   • Set TARGET to the desired name of the output file (eg: TARGET = main)
   • Set SOURCES to a list of your sources (eg: SOURCES = main.c startup_gcc.c)
   • Set TIVAWARE_PATH to the full path to where you extracted and built TivaWare (eg: TIVAWARE_PATH = /home/eric/code/tivaware)

3. Run make

4. The output files will be created in the 'build' folder

The easiest way to flash your device is using lm4flash. First, grab lm4tools from Git.

git clone git://github.com/utzig/lm4tools.git

Then build lm4flash and run it:

cd lm4tools/lm4flash
make
lm4flash /path/to/executable.bin

If you need libusb: sudo apt-get install libusb-1.0-0-dev

Copy lm4tools into /opt: sudo cp -avr lm4tools /opt Add to PATH: PATH=$PATH:/opt/lm4tools/lm4flash

Plug TI launchpad while monitoring the process:

tail -f /var/log/syslog

*Write idVendor/idProduct values on a notepad.

(you may stop modem manager: sudo stop modemmanager)

Use lm4flash main.bin command to program your board with main.bin. It may complain:

sg@sg-sajat:~/__WORK__/tivac/tiva-template/build$ lm4flash main.bin
Unable to open USB device: LIBUSB_ERROR_ACCESS
Unable to find any ICDI devices

That is, you have no access to the device. You need to create a rule:

sudo gedit 30-tivac.rules

Add this to the empty file (you need to replace idVendor/idProduct with your own ones):

KERNEL=="ttyACM[0-9]*",ATTRS{idVendor}=="1cbe",ATTRS{idProduct}=="00fd",MODE:="0666"

Execute udevadm trigger. Unplug-replug your board.

sg@sg-sajat:~/__WORK__/tivac/tiva-template/build$ lm4flash main.bin
Found ICDI device with serial: 0E200FBE
ICDI version: 9270

These chips are supported in openocd HEAD (credit to Karl Palsson). The openocd website has instructions on how to install it.

With openocd installed, run gdb with this command:

arm-none-eabi-gdb -ex 'target extended-remote | openocd -f board/ek-tm4c1294xl.cfg -c "gdb_port pipe; log_output openocd.log"; monitor reset; monitor halt'

lmicdi can also support gdb but it appears openocd has better support for breakpoints and source-level debugging right now. You may want to check back later for updates on the situation.

Thanks to Recursive Labs for their guide which this template is based on.

Thanks to Rob Stoddard for digging into the issue on soft FP versus hardware FP.
