Thanks deepak, I got the sytem.tar and data.tar file. I am trying to port the android stuff on nokia 800 with updated touchscreen patch. I got the kernel image also.

In the given below steps :

**************************************************************************** #### Format the MicroSD card

1. Insert the MicroSD card into the N8XX 2. Connect the N8XX to your computer via USB 3. Flash the MicroSD card

> mount /dev/sdc1 /media/usbdisk-1

> exit

#### Extract the userspace

cp android-sdk_m3-rc37a/tools/lib/images/ramdisk.img ramdisk.gz

gunzip ramdisk.gz cd /media/usbdisk-1

cpio -iv < $ANDDIR/ramdisk

mkdir dev/log touch dev/log/main

touch dev/log/events touch dev/log/radio

### Extract system.tar from the sdcard image

su mkdir card

mount -o card.img card tar -xvf card/system.tar -C /media/usbdisk-1

#### Apply the file system patch (will be available shortly)

cd /media/usbdisk-1

cat $ANDDIR/userspace_android-m3-rc37a_N8XX.bz2 | patch -p1

************************************************************************************ 1) Please Confirm, Is it neccary to purchase MicroSD card for android porting on Nokia N8XX? 2) Why data.tar file is not extracted from sdcard image ? That steps is missing here? 3) What is here "userspace_android-m3-rc37a_N8XX.bz2 " ?

Deepak,

I tried with that command only, getting the same error. I am facing problem in creating tar of /system and /data. At present, I am thinking to use the given android file system(system.tar.gz and data.tar.gz) from "http://elinux.org/Android_on_OMAP".

Hi,

Please try this:

cd /sdcard busybox tar -cvf system.tar /system busybox tar -cvf data.tar /data

cd /system/bin ln -s busybox tar ln -s busybox gzip cd /sdcard busybox tar -cvzf system.tar.gz /system busybox tar -cvzf data.tar.gz /data

Hi,

Thanks for providing useful link. Still, I need some clarification from all expert. I am getting some issues, while creating tar file for filesystem(File Sytem - step 5). I added busybox (ARM-cross-complied) to Android SDK- emulator(m3-37).After linking this busybox executable to /sbin/tar, When I am trying to run tar command. Its giving "Tar not found". Why I am not able to run busybox command inside emulator? Can we use the available Android file system image ( system.tar.gz & data.tar.gz.) ? Is it necessary to purchase Micro SD card? We can not do it on existing free space in N810. What is here "userspace_android-m3-rc37a_N8XX.bz2"?

Is their any way to keep the original Kernel as it is, and flashing the android stuff as dual OS?

Hi All,

I am trying to port the android on Nokia N810. I am new into embedded development platform. I am trying my best to

understand

the

given procedure in "http://www.elinux.org/Android_on_OMAP".

As per my understanding, these are the few steps which needs

to be

done.

1) Get the kernel patch. 2) Get the Android File System(/system and /data) 3) Kernel and File System Configuration on Real Target i.e

Nokia

N810

4) Integrating the Kernel and File System using scripts, and starting of android

I think, The first two steps, one can easily get from the given available link.

I am not clear in steps 3 and having some few query. How to go ahead in configuring the kernel and file system on Real target(N810)? In given steps, its mentioned steps wrt Linux-2.6.23 and N810 is having Linux-2.6.21. Which kernel version and final package to take? Is it possible to keep the original running kernel on N810

active

and

flashing the new android-kernel(for ex- dual boot) ?

Any help will be highly appreciated. Thanks in Advance.

Hi,

Follow the below step:

deepak@ cd <path_to>/android-sdk_version_linux-x86/tools deepak@ export PATH=${PATH}:<path_to>/android-sdk_version_linux-x86/tools (Set path to emulator tools) deepak@ mksdcard -l card 100M card.img (Create an empty SDcard (image)) deepak@ emulator -sdcard card.img -console -debug-kernel (Start emulator)

The SDK kernel booting and emulator starting. Wait until the emulator is ready, then send the ARM busybox from the host into the simulated environment:

(please find the attach busybox)

deepak@ adb -d 1 push <path_to>/busybox /system/bin/busybox (open another console(because emulator running in one console))

android# cd /sdcard

android# busybox tar -cvf system.tar /system android# busybox tar -cvf data.tar /data

deepak@ adb pull /sdcard/data.tar . deepak@ adb pull /sdcard/system.tar .
