1 Introduction

This report is based on Master of Science project in Laboratory of Intelligent Multimedia Processing

(LIMP)1 of Computer and Information Technology Department2 in Amirkabir University of

Technology3 (Tehran Polytechnic). It supervised by Dr. Mohammad Mehdi Homayounpour4. First

section describes Friendlyarm Micro 2440 board. Next section is about how to use it and how to install

operating systems such as Linux, Windows, and Android. To use this board, you need some software

that is available on DVD in package of board. If you do not have access to that DVD, you can download

them5.Images of Linux and Windows CE is distributed through Friendlyarm. For Installing android,

you should create image and this document shows how to do it. Also, you can download the said image

created by me from the following link: http://ceit.aut.ac.ir/~badamchi/micro2440/micro2440W35-

android.img.

Notice: This report is free to use for everyone. If you want to use any content of it, you should coordinate

with the laboratory supervisor.

Do not hesitate contacting the author for any comment on this document through

amir.badamchi@gmail.com. Moreover, you can access the latest version of this document from

following link: http://ceit.aut.ac.ir/~badamchi.

Ultimately, I thank the almighty God for helping in furthering this project. In addition, I should thank

Dr. Mohammad Mehdi Homayounpour and all member of LIMP lab for their endless support.

3 How to use

To use this board, you should connect both USB and serial ports to the computer. Friendlyarm provides

DNW application for facilitate your woks. Next section will explain how to use this board in Windows.

Using the board in Windows

You should use DNW application to connect the board. At first step, you should connect USB and serial

cables to the computer. Next, go to Configuration in “Options” menu in DNW and select “port

number”. Then, click on “Connect” in “Serial Port” menu. Now put mode switch on board in

NOR mode and turn on switch power. If everything is ok, this picture will be shown to you.

Now, press “v” key on keyboard and select USB Port in Transmit menu. Then select supervivi-128M

file on your computer to transfer it to flash memory.

Select “k” key and specify zImage file to write to the memory.

Now, press “y” to install Yaffs and select root_qtopia-128M to transfer it.

Now, turn off the board and put boot mode switch on NAND. Then, turn on the board. You are in qtopia

now.

3.1.2 Install Windows CE

Similar to linux installation, first format NAND flash memory by selecting x. Type “v” key, then select

supervivi-128M. Next, select “n” and nboot_W35. Now, press “l” to select Windows CE logo. Finally,

type “w” and select NK_W35 to write on NAND flash. Put boot mode switch on NAND and reset board

to use windows.

3.1.3 Install Android

To install android, you should create images in Linux and port it on NAND flash. in this step, Ubuntu

12.04 is used. These files are needed for creating image files:

arm-linux-gcc-4.4.3.tar.gz

android-kernel_20090825.tgz

android-fs_20090825.tgz

mkyaffs2image.tgz

We use gcc linux and arm version. Extract the file whose name is arm-linux-gcc-4.4.3.tar.gz. Go to

terminal in Ubuntu and run this command.

tar –xvzf arm-linux-gcc-4.4.3.tar.gz –C/

After running this command, Friendlyarm directory will be created in “opt” folder.

3.1.3.1 Create Android kernel image

Enter this command to extract file android-kernel_20090825.tgz by typing this command in terminal:

tar -zxvf android-kernel_20090825.tgz

Micro2440’s display is W35; however display in this image file is T35; therefore, we should have some

changes.

Go to folder kernel/arch/arm/mach-s3c2440 and open file mach-mini2440.c in Text Editor. Go to line

169.

#elif defined(CONFIG_FB_S3C2410_T240320) #define LCD_WIDTH 240

#define LCD_HEIGHT 320

#define LCD_PIXCLOCK 170000

#define LCD_RIGHT_MARGIN 29 #define LCD_LEFT_MARGIN 10

#define LCD_HSYNC_LEN 5

#define LCD_UPPER_MARGIN 3 #define LCD_LOWER_MARGIN 5

#define LCD_VSYNC_LEN 1

Replace these lines.

#elif defined(CONFIG_FB_S3C2410_T240320) #define LCD_WIDTH 320

#define LCD_HEIGHT 240

#define LCD_PIXCLOCK 170000 #define LCD_RIGHT_MARGIN 68

#define LCD_LEFT_MARGIN 4

#define LCD_HSYNC_LEN 5 #define LCD_UPPER_MARGIN 10

#define LCD_LOWER_MARGIN 4

#define LCD_VSYNC_LEN 1

Now go to kernel/drivers/input/touchscreen and open s3c2410_ts.c file in editor, go to line 99.

disX = disX * 1024 / 240;

disY = disY * 1024 / 320;

Replace these lines.

disX = disX * 1024 / 320;

disY = disY * 1024 / 240;

Save your changes.

Now go to terminal and enter this command to specify compiler path.

export PATH=/opt/FriendlyARM/toolschain/4.4.3/bin:$PATH

Go to kernel folder and enter these commands

cp config_mini2440 .config

make menuconfig

You will see Linux kernel configuration window.

Press Exit, enter this line to create image file. It may take some seconds.

make zImage

Image file will be created in “kernel/arch/arm/boot” directory.

3.1.3.2 Create system file image

Extract file android-fs_20090825.tgz by this command.

tar -zxvf android-fs_20090825.tgz

Language settings are in default.prop file. To change language to English, replace these lines

persist.sys.country = CN persist.sys.language = zh

persist.sys.timezone = Asia/Hong_Kong

with these lines and save it.

persist.sys.country = US persist.sys.language = en

persist.sys.timezone = GMT+3:30

Now extract mkyaffs2image.tgz file by this command:

tar -zxvf mkyaffs2image.tgz

By running this command, files will be copied in usr/sbin directory. We should copy them to current

folder.

# cp usr/sbin/mkyaffs2image-128M mkyaffs2image-128M

Ultimately, enter this command to create system file image:

./mkyaffs2image-128M fs/ mini2440W35i_android.img

To install android, like Linux, format NAND flash memory and copy these files.
