========
Some tools which enable multi-platform development on the TI Stellaris Launchpad boards. The Stellaris Launchpad is a low cost development board created by Texas Instruments that comes with an ARM Cortex-M4F processor. You can get one here:
[Get a Stellaris Launchpad](http://www.ti.com/ww/en/launchpad/stellaris_head.html?DCMP=stellaris-launchpad&HQS=stellaris-launchpad-b)
__Included tools__
* lm4flash
Command-line firmware flashing tool using libusb-1.0 to communicate with the Stellaris Launchpad ICDI. Works on all Linux, Mac OS X, Windows, and BSD systems.
GPLv2+ license. See lm4flash/COPYING for details.
* lmicdiusb
TCP/USB bridge created by TI, letting GDB communicate with the Stellaris Launchpad ICDI. Works on all Linux, Mac OS X, and BSD systems. Currently not on Windows, due to the use of poll() which does not work for USB on Windows.
BSD-style license. See lmicdiusb/license.txt for details.
__Setting up a development environment__
First you'll need a cross compiler able to compile for ARM Cortex-Mx aka arm-none-eabi-. Some which are know to work:
* [summon-arm-toolchain by Piotr Esden-Tempski](https://github.com/esden/summon-arm-toolchain)
* [arm-eabi-toolchain by James Snyder](https://github.com/jsnyder/arm-eabi-toolchain)
* [Sourcery Codebench Lite](http://www.mentor.com/embedded-software/sourcery-tools/sourcery-codebench/editions/lite-edition/request?id=e023fac2-e611-476b-a702-90eabb2aeca8&downloadlite=scblite2012&fmpath=/embedded-software/sourcery-tools/sourcery-codebench/editions/lite-edition/form)
More info can be found here [eLinux toolchains](http://elinux.org/Toolchains).
Grab StellarisWare from Texas Instruments: [Stellaris LM4F120 LaunchPad Evaluation Board Software](http://www.ti.com/tool/sw-ek-lm4f120xl). You need to get SW-EK-LM4F120XL.
Inside StellarisWare directory you'll find many examples in the directory *boards/ek-lm4f120xl*. Try building project0 by going to that directory and running *make*.
To flash your Stellaris board from *boards/ek-lm4f120xl/project0*, run:
$ lm4flash gcc/project0.bin
Nice hacking!
__Optional: Remove the root requirement__
By default, root permissions are required to flash the Stellaris Launchpad ICDI. This can be circumvented by adding udev rules.
Create a file called */etc/udev/rules.d/61.stellpad.rules*, containing:
```
SUBSYSTEM=="usb", ATTRS{idVendor}=="1cbe", ATTRS{idProduct}=="00fd", MODE="0666"
```
Restart udev to apply the changes.
