How to Download Keil uVision and Other Software for Tiva LaunchPad

This tutorial is intended for the first-time user of Texas Instruments Tiva LaunchPad (EK-TM4C123GXL). It covers the downloads and installations of all the necessary software to program the LaunchPad.

The required software components are:

• Keil uVision IDE and RealView MDK v4.54 or newer – You may use other toolchain to develop and program the Tiva LaunchPad. In this tutorial we will only discuss the procedures for Keil toolchain.

• ICDI drivers – Tiva LaunchPad comes with an integrated In-Circuit Debug Interface (ICDI) which allows programming and debugging of the onboard microcontroller. The drivers needed by the host computer to communicate with the Tiva LaunchPad are Stellaris Virtual Serial Port, Stellaris ICDI JTAG/SWD, and Stellaris ICDI DFU.

• LM Flash Programmer – It is a stand-alone utility for programming of the MCUs. The IDEs also use it to program the device.

• TivaWare – a collection of royalty-free libraries for peripherals and code examples.

Downloads

1. Browse to www.ti.com/tool/sw-ek-tm4c123gxl.

2. If you do not have Keil RealView MDK installed on your computer, EK-TM4C123GXL-KEIL will be the choice. It contains all the require software components to program the Tiva LaunchPad. The package is quite large (~500 MB) and will take a while to download. In this tutorial, we will focus on the installation of this software package.

3. If you already have the Keil RealView MDK v4.54 or newer, you may download the rest of the components separately.

ICDI Drivers – http://www.ti.com/tool/stellaris_icdi_drivers

LM Flash Programmer – http://www.ti.com/tool/lmflashprogrammer

TivaWare (Complete) – http://www.ti.com/tool/sw-tm4c

There are several different components of the TivaWare. You may download only the ones you need or you may download the complete collection.

Installations

In this section, we will discuss the installation of the software package downloaded in step 2 above. The downloaded file is EK-TM4C123GXL-KEIL-753.zip.

4. Unzip the file and you will have a folder named EK-TM4C123GXL-KEIL-753.

The folder contains four subfolders:

• Documentation – contains the documentation of the board, the device, and the software

• Drivers – the device drivers for the host PC

• TivaWare

• Tools – installation packages of Keil uVision IDE and RealView MDK and LM Flash Programmer

Documentation

There are n documents in this folder:

Board\ spmu296.pdf – the Tiva LaunchPad User’s Guide. It contains the overview, hardware description, software development, PCB layout, bill of material, and schematics.

Device\ Datasheet-TM4C123GH6PM.pdf – the datasheet of the microcontroller on the Tiva LaunchPad

Device\ errata-TM4C123GH6PM.pdf – the errata of the datasheet

Device\ ROM-TM4C123GH6PM-UG-750.pdf – the TivaWare Peripheral Driver Library and the TivaWare

Boot Loader are programmed into the ROM of the microcontroller on the Tiva LaunchPad. Programmer may take the advantage of calling these functions without having to link the library code into the program, thus reduces the memory usage.
