Setting up Eclipse and LM Flash Programmer

i) Launch the Eclipse IDE. A window similar to that shown will come up,

ii) Installing the GNU ARM Plugin

Go to Help -> Install New Software -> Add -> Archive

A window similar to that shown in below will show.

Browse to the GNUARM plugin zip file downloaded earlier.

Click Ok and Next to install the plugin.

A window similar to that shown will show.

iii) Creating your first project

Go to File -> New -> C Project.

Enter the project name. Make sure the selections are as shown below

Click Next.

Enter the Project Name as shown.

Then, press Finish.

iv) Importing the existing file system.

Go to File -> Import -> General -> File System.

A window similar to that shown below will come up.

Press Next.

Browse and select the any project from the lm3s608 folder (Source Code for your project). Make sure same option as shown in figure are selected. Press Finish.

So till now, we have set up a new project and instructed the Eclipse IDE as to what cross compiler to use for development. Your screen should look similar to that shown in Figure below.

v) Setting up project properties

Go to Project Properties.

Under Settings -> Tool Settings -> ARM Sourcery Windows GCC C Compiler -> Directories. Include the directory paths as shown below.

Choose cortex-m3 as the processor

Assembler Flags

'gcc' is the defined symbol used

Include the location of the code 

-ffunctions-sections parameter required

Set the Linker location and options

Static Library for the linker

Paths and Symbols

Add arm-none-eabi-objcopy -S -O "${ProjName}.elf" "${ProjName}.hex" to Post-Build Steps

And yes! You are ready to fire up your main.c and code away. To compile, just build. Get the hex file being built, Don't let those many lines running in the eclipse console cause you to worry. 

Use the LM Flash Programmer to burn the file to the board. You can integrate the LM Flash Programmer with Eclipse using the External Tools Configuration. 

Go open the external tools configuration, Run -> External Tools -> External Tools Configuration 

Double click Program to configure a new external tool. Fill in as shown in the next figure. Make sure you choose the correct location of LMFlash.exe 

Now, these steps need not be repeated everytime you create a new project. Just create a project_template once, and the next time you want to create a new project just make a copy of project_template, rename it and change the location of the linker file in the project properties.

Next up, configuring OpenOCD with eclipse for debugging with linux.

arm-none-eabi-objcopy -S -O binary project_template.elf project_template.bin // Converts .elf file to binary file

arm-none-eabi-objdump -d text.o > text.txt // To get the assembly file, being burnt to the controller
