In this post I shall demonstrate the ways of developing programs for mini2440 using Code Blocks.

Code Blocks is a free cross platform IDE with powerful features.

Install Code Blocks using the Ubuntu Software Center.Just type code blocks in the search box & click install.

After installation ,the Code Blocks icon appears on the Launch bar.

    Ubuntu Software Center_003

Click the Icon to fire Up Code Blocks.To start a new program Click Create New Project button.

code_blocks

 

Select  Console Application ,click Go button & in the next window select C as the language.

 console_app   select_c

Click Next & provide a name for your project,e.g., welcome.

  Console application_026 

Select the Compiler as “GNU ARM GCC Compiler”.

  select_compiler 

Click Next to see the Workspace window.To the left hand side under Projects tab you can see the project name “welcome” & if you expand Sources you can see  main.c file automatically created.Double click this main.c file.    

       main.c

By default , a sample Hello world program is presented.

As we are cross compiling the program for ARM platform ,we’ve to do the Compiler settings as below:

Click Settings –> Compiler and Debugger

comp_set

Under selected compiler make sure that the entry is GNU ARM GCC Compiler.

Now select the Tab Toolchainexecutables.

    Compiler and debugger settings_045

This part is the most important part of Compiler settings.Please take care to select as per screenshot below :

       Compiler and debugger settings

The Compiler’s installation directory is /opt/FriendlyARM/toolschain/4.4.3/

For installation procedure of cross compiler read the previous post here.

Under the Program Files tab make sure the settings are as below :

                   C compiler          :   arm-none-linux-gnueabi-gcc-4.4.3

                 C++ compiler       :  arm-none-linux-gnueabi-c++

Linker for dynamic libs       : arm-none-linux-gnueabi-g++

Linker for static libs            : arm-none-linux-gnueabi-ar

                  Debugger            : gdb

               Make Program     : make

To select the path click on the eclipses ..  & browse to the directory

            /opt/FriendlyARM/toolschain/4.4.3/bin

Inside this bin directory you see all the require Program files.Select as per list above.

path2

The Debugger used is gdb & the path is

/opt/FriendlyARM/toolschain/4.4.3/arm-none-linux-gnueabi/debug-root/usr/bin

debug_path

Click OK to arrive at workspace.

Now feed the code as below ,just to print out message “Welcome to FriendlyARM…!” 5 times:

    appln_1

Click File –> Save All & then click Build –>Build

     build

Note that if you select Build and Run you’ll get error, as this program is intended to run on ARM platform & not on your x86 PC.

              run_error

Just click on Build.The bin file is ready to be transferred on to the target ARM device,mini2440.

By default the result file is stored in your Home.

Open File system ,browse to /Home/welcome/bin/Debug

                    binfile

There you find your final output executable bin file “welcome”.

To transfer this file on to the target device,use FTP method.Open the Linux Terminal & change directory to the folder where your final output file exists.Here it is 

/Home/welcome/bin/Debug.

To start ftp type  ftp 192.168.1.230  which is the IP ADDRESS of our target device MINI2440.

                  start_ftp

Type in the Name as plg  & password also as plg.

Now  the ftp> prompt appears where you type bin to set the type of file to be transferred.

Type > put welcome

to transfer the file welcome on to mini2440.

            ftp_3

Now it is time to test you program on the Target device.Open up the PuTTY Terminal

(Read the setup procedure here in  previous post setup).

& change directory to /home/plg

Under  plg directory is the welcome file you transferred from PC.

Type  # chmod +x welcome

to give Execute Permission to the welcome file.

     execute_1

Now type # ./welcome 

  ( dotforward slash filename ).

Congrats!! You see the result of welcome program.Instead of executing this within PuTTY terminal you can do this on the Target device by opening the terminal built in it.
