Porting android on s3c6410
Environment: ubuntu 8.10
Board: XX6410
Kernel version: linux 2.6.24, android 1.0
1.Copy files
Create working location: /mydroid and copy the following files to this location:

Filename
Description
samsung-s3c6410-android.1.0.tar.bz2
Kernel
kandroid-1.1.2.1-20080530.glibc.gz
libiconv-1.12.tar.gz
Toolchain
090227-android-cupcake-rootfs.tar.bz2
Cupcake root file system
u-boot.bin
DNW
Bootloader

Below is the list of files:

tommy@tommy-desktop:~$ mkdir mydroid
tommy@tommy-desktop:~$ cd mydroid
tommy@tommy-desktop:~/mydroid$ ls
090227-android-cupcake-rootfs.tar.gz libiconv-1.12.tar.gz
DNW samsung-s3c6410-android.1.0.tar.bz2
kandroid-1.1.2.1-20080530.glibc.tgz u-boot.bin
2.Installing Toolchain
Please follow the commands below and install the tool chain in the directory mentioned below:
installing libiconv
tommy@tommy-desktop:~$ cd mydroid
tommy@tommy-desktop:~/mydroid$ tar xvf libiconv-1.12.tar.gz
tommy@tommy-desktop:~/mydroid$ cd libiconv-1.12
tommy@tommy-desktop:~/mydroid/libiconv-1.12$ ./configure --prefix=/usr/local
tommy@tommy-desktop:~/mydroid/libiconv-1.12$ make install
tommy@tommy-desktop:~/mydroid/libiconv-1.12$ vi /etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/local/lib
tommy@tommy-desktop:~/mydroid/libiconv-1.12$ ldconfig

installing toolchain
tommy@tommy-desktop:~$ cd ~/mydroid
tommy@tommy-desktop:~/mydroid$ tar xvf kandroid-1.1.2.1-20080530.glibc.tgz
tommy@tommy-desktop:~/mydroid$ sudo mkdir -p /usr/local/arm
tommy@tommy-desktop:~/mydroid$ sudo mv kandroid-1.1.2.1-20080530.glibc /usr/local/arm
3.Compiling Kernel
Kernel source is compressed by the name of ‘samsung-s3c6410-android.1.0.tar.bz2’. This is patched for s3c6410 so you don’t need to do this step. Extect this bz2 file by executing command. After extracting the kernel tarball file ‘samsung-s3c6410-android.1.0’

tommy@tommy-desktop:~/mydroid$ tar jxvf samsung-s3c6410-android.1.0.tar.bz2
tommy@tommy-desktop:~/mydroid$ cd samsung-s3c6410-android.1.0

Define the path of toolchain for cross-compiling. Open file Makefile in this folder ( samsung-s3c6410-android.1.0 ). Go to line 197 and set:

CROSS_COMPILE   := /usr/local/arm/kandroid-1.1.2.1-20080530.glibc/bin/arm-android-linux-gnueabi-

Set the configuration values for the kernel. At first, copy the default configuration files which is located in arch/arm/configs/ to be the configuration file.
tommy@tommy-desktop:~/mydroid/samsung-s3c6410-android.1.0$ cp arch/arm/configs/smdk6410_android_nfs.config ./.config

Change default configurations by excuting ‘make menuconfig’

tommy@tommy-desktop:~/mydroid/samsung-s3c6410-android.1.0$ make menuconfig

please select ‘Boot options’, enter value for ‘Boot options’: boot from nfs file. Follow the below syntax :

root=/dev/nfs rw nfsroot=/ ,rsize=1024,wsize=1024 ip= :: :255.255.255.0::eth0:off init=/init console=ttySAC0,115200

Please change ip config to suite your PC’s configuration
My values:
root=/dev/nfs rw nfsroot=192.168.11.2:/nfsroot/090227-Android-cupcake-rootfs,rsize=1024,wsize=1024 ip=192.168.11.3:192.168.11.2:192.168.11.2:255.255.255.0::eth0:off init=/init console=ttySAC0,115200s

Please select 'Power management' , set 'Power_Suspend=y'

Finally, make the kernel image file by executing:’make zImage’,copy the image to the tftp root folder.

tommy@tommy-desktop:~/mydroid/samsung-s3c6410-android.1.0$ make zImage

.......
LD      vmlinux
SYSMAP System.map
SYSMAP .tmp_System.map
OBJCOPY arch/arm/boot/Image
Kernel: arch/arm/boot/Image is ready
AS      arch/arm/boot/compressed/head.o
GZIP    arch/arm/boot/compressed/piggy.gz
AS      arch/arm/boot/compressed/piggy.o
CC      arch/arm/boot/compressed/misc.o
LD      arch/arm/boot/compressed/vmlinux
OBJCOPY arch/arm/boot/zImage
Kernel: arch/arm/boot/zImage is ready

tommy@tommy-desktop:~/mydroid/samsung-s3c6410-android.1.0$ cp arch/arm/boot/zImage /TFTP
4.install nfs server and copy root file system
Please follow the below commands to install nfs server and copy cupcake root file system into the nfs server’s root folder

tommy@tommy-desktop:~$ cd ~/mydroid
tommy@tommy-desktop:~/mydroid$ tar xvf 090227-android-cupcake-rootfs.tar.gz
tommy@tommy-desktop:~/mydroid$ sudo apt-get install nfs-kernel-server portmap
tommy@tommy-desktop:~/mydroid$ sudo mkdir /nfsroot
tommy@tommy-desktop:~/mydroid$ sudo mv 090227-Android-cupcake-rootfs /nfsroot
tommy@tommy-desktop:~/mydroid$ sudo vim /etc/exports
insert:
/nfsroot/090227-android-cupcake-rootfs *(rw,no_root_squash,no_all_squash)
tommy@tommy-desktop:~/mydroid$ sudo /etc/init.d/nfs-kernel-server restart
5.Porting Android
The first step to port android on S3c6410 board is uploading u-boot.bin . This step is perfomed only 1 time. Because I don’t know how to uploading u-boot.bin on linux environment using USB cable so I move into WindowXP environment and uploading this file using DNW. Please see ‘XX6410 linux 2.6 Guide’ for more detail
a.Uploading ‘u-boot.bin’ using USB 2.0 Cable on WindowXP environment
Please copy 2 file: u-boot.bin, tftpserver-setup and DNW folder to Windowxp environment.
Step 1: Installing tftpserver

Step 2: Copy file u-boot.bin into tftp root folder.

Step 3: Change NOR Flash Boot Mode:

Step 4: Run dnw.exe in DNW folder.
On the Configuration menu, click Options to set the UART/USB options. The following
window appears on your screen. Select Baud Rate and COM Port as shown in figure
“UART/USB options”, enter the download address as 0x57e00000 and then click OK
button.

On the Serial Port menu, click Connect. Switch ON the reference board and then press
any key and then install the USB driver in DNW driver directory

Enter “0”, On the USB Port menu, click Transmit and the following window appears on
your screen. Select u-boot.bin file and then
click Open button.

As soon as u-boot.bin download is over, the following messages appear in the DNW
window. Please hit the SPACE BAR key to view the current Ethernet Boot Loader
Configuration. Configure the Ethernet Boot loader as follows by entering the respective
options.

Setting IP address: set your ip address as serverip and a ramdom ip for the board
TFTP Server IP : setenv serverip 192.168.0.232
Device PC IP : setenv ipaddr 192.168.0.236
For erasing Bad blocks in NAND : nand scrub

Input ‘Y’ directly hit ‘Enter’

tftp c0000000 u-boot.bin
nand erase 0 40000

nand write c0000000 0 40000

Please reboot After Setting NAND of Boot Mode

Now, u-boot.bin is uploaded on the board. You don’t need perform this step more. Restart PC and come back liux environment. Now, our working environment is only Linux.
b.Uploading kernel image using Minicom on Linux
If your system has not minicom , please install Mincom using apt-get.
tommy@tommy-desktop:~$ minicom -s : Execute minicom on setting mode

Please select ‘Serial port setup’ and set configuration as below:

Restart minicom, then restart the board and hit SPACE BAR immediately. On Mincom screen:
