porting android

[bhoj]

hello friends,

I am new to android. I am sorry if am discussing this in a worng
community.
i am trying to port android on omap3evm,
i have followed the procedure given in
http://labs.embinux.org/wiki/index.php/Android_Porting_Guide_to_Beagle_Board
. I added the android specifics in config file and i could build the
kernel. I tried it with the filesys given by embinux team but i failed
and got the error

<4>Warning: unable to open an initial console.
Warning: unable to open an initial console.
<0>Kernel panic - not syncing: Attempted to kill init!
Kernel panic - not syncing: Attempted to kill init!

the bootargs which i used are console=ttyS0,115200n8=noinitrd rw
ip=192.168.1.78 root=/dev/nfs nfsroot=192.168.1.77:/home/vishal/
workdir/filesys,nolock mem=128M video=omap24xxfb:rotation=90 init=/
init

I have few questions,
1.Is my approach right ?
2. If it is right then what could be the problem.
or If the approach is wrong then how should I try ?

Hi,

I'm not sure if this the past approach since the source was released.
You may want to following this thread

Also, chmod -R 777 the whole filesystem. The chmod -R 666 in the
instructions gave me the same error messages you saw. I'm sure
chmoding the entire filesystem is overkill, but it works.

[Rupesh Gujare]

Vishal,
Which kernel you are using? Are you using kernel for omap3evm along
with Android patches? Kernel configuration mentioned on wiki page, is
for beagle board.

Rupesh,

I am using 2.6.25 Kernel . i checked out
git checkout -b beagle.android labs.embinux/android

then I modified omap3_evm_defconfig to enable android specific
configurations and I could build the Kernel.
while building filesystem i got this error
-----
#
Unrecognized option : 9999999
#
make: *** [out/host/common/obj/JAVA_LIBRARIES/
clearsilver_intermediates/javalib.jar] Error 41
#
make: *** Waiting for unfinished jobs....
----
so i used the filesystem provided by you.
Is my approach correct ?

Howard,
i did chmod -R 777 it did not help me.

hello Rupesh,

I get the android robot on the screen but after that nothing happens. when I checked the log i see that dalvik-cahce/ elements are not getting created.
I have put the logs here 

http://pastebin.com/d3b038a0a
Can anyone tell me the reason why it is failing .
It'll be of great help.

Vishal,
   Take fresh RFS as well change permission for complete RFS to 777.
$chmod -R 777 /path_to_android_RFS

Hi, I am new with Linux so I have this question:

When I do compile kernel with Android patches where should I start in the terminal? Which kernel version I should use? and when I compile with

make ARC=arm CROSS_COMPILE=PATH_TO_CODE_SOURCERY_TOOL_CHAIN uImage

I have PATH = $HOME//CodeSourcery/Sourcery_G++_Lite/bin

then I got: make: *** No rule to make target 'uImage'.

 

Could you please tell me what I should do?

You can use kernel from embinux site, you should use kernel version is 2.6.27.
 

and when I compile with

make ARC=arm CROSS_COMPILE=PATH_TO_CODE_SOURCERY_TOOL_CHAIN uImage

I have PATH = $HOME//CodeSourcery/Sourcery_G++_Lite/bin

then I got: make: *** No rule to make target 'uImage'.

Are you following steps from embinux wiki page ? You should not get this error if you are following it.

Hi Rupesh,

I am following the android Porting guide on Beagleboard.
I did the following steps:

$git clone git://source.mvista.com/git/linux-omap-2.6-historic.git

------> Please see "linux-omap-2.6-historic.git". Is it correct ?
This creates linux-omap-2.6-historic and not "linux-
omap-2.6" as written in porting guide ..
so is the URL correct ?

$cd linux-omap-2.6-historic
$git remote add labs.embinux git://labs.embinux.org/linux-omap-2.6
$git remote update

For 2.6.27 Kernel-
$git checkout -b beagle.android-2.6.27 labs.embinux/android-2.6.27

$make ARCH=arm omap3_beagle_android_defconfig
#
# configuration written to .config

Now, I get following ERROR---------------------

Which tool chain you are using ? Above command expects path to "arm-none-linux-gnueabi-gcc" after CROSS_COMPILE=.

Regards,
Rupesh Gujare
 

[sonal]

i am using CodeSourcery Sourcery G++ Lite 2007q3-51) 4.2.1

My make command looks like this :
make ARCH=arm CROSS_COMPILE=/home/test/arm2007-q3/arm-2007q3/bin/arm-
none-linux-gnueabi- uImage


is the error linked to HOSTCC , than the Cross compile toolchain by
any chance?
I am just guessing ?
my HOSTCC is gcc (GCC) 4.2.4 (Ubuntu 4.2.4-1ubuntu3)

Please help....

[Rupesh Gujare]

Sonal,
 It works fine for me with following toolchain and host gcc versions

gcc version 4.2.1 (CodeSourcery Sourcery G++ Lite 2007q3-51)
gcc version 4.3.2 (Ubuntu 4.3.2-1ubuntu12)

Regards,
Rupesh Gujare

[sonal]

ok. I will try to upgrade to gcc 4.3.2 and try....
but does it have any such dependencies on HOSTCC ??

I believe it should not have any dependency on HOSTCC for compiling kernel. Although I am not 100% sure.

Ok i could build 2.6.25 kernel, so i will stick with that for now...

Hi Rupesh,

I am following the steps to build the android now..
I could apply patches for Tls and Gl Wrapper, but I am stuck when
applying alsa_sound patch.

On giving this command : "patch -p1 < ~/Alsa_sound-v1.1.patch"

I get the following :
Reversed (or previously applied) patch detected! Assume -R? [n]
I gave [n], and asked to apply the patch anyway..


Then it stops like this:
Hunk #1 FAILED at 30.
Hunk #2 FAILED at 106.
Hunk #3 FAILED at 187.
Hunk #4 FAILED at 218.
Hunk #5 succeeded at 985 with fuzz 1 (offset 70 lines).
Hunk #6 succeeded at 1071 with fuzz 1 (offset 77 lines).
4 out of 6 hunks FAILED -- saving rejects to file

Reversed (or previously applied) patch detected! Assume -R? [n] n

Hunk #3 FAILED at 213.
3 out of 3 hunks FAILED -- saving rejects to file
AudioHardwareALSA.h.rej
can't find file to patch at input line 253
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------

|index 68fa70e..8946bde 100644
|--- a/AudioHardwareInterface.cpp
|+++ b/AudioHardwareInterface.cpp
--------------------------
File to patch:



================================
Is there something wrong in the way i am applying the patch ?

Ok i am skipping the alsa patch and going ahead with the build,
without alsa support..

I got the build done.
Am I supposed to see any contents in android_build/out/target/product/
generic/data folder.. ??
It is empty ....

Just wanted to confirm..

[Rupesh Gujare]

It will be empty.

[Rupesh Gujare]

Sonal,
  I have updated wiki page, as per your findings. I have reconfirmed compilation of 2.6.27-android kernel. It is working fine for me. Please note that, latest android build will work with 2.6.27 version.

[sonal]

Ok ,
I will try compiling 2.6.27 again.

Could you tell on which version is the pre-built kernel image ?

Because the pre-built uImage could detect the USB hub, but the 2.6.25
kernel does not.

Will 2.6.27 kernel work ? Will it give the same uImage as the pre-
built one ?

Yes, It ll give same uImage as prebuild one.

old  ALSA patch is no more applicable as there had been update to alsa_sound repository few days back.

ok i am still getting the same issue with 2.6.27. kernel..
sorry to bother you..but could u tell me these two things..

a) how to check if i have modified anything locally in the kernel
source.. i mean i want to get the original checkled-out 2.6.27,
without having to download everything again..
b) how to update to gcc version 4.3.2 (Ubuntu 4.3.2-1ubuntu12)

I know this are not the relevant questions.. but i am stuck !! :(

[sonal]

ok..
i do $git diff, and nothing is printed on the console.. i assume that
means that nothing is modified.
so, the only other doubt remains is the : updation to gcc
4.3.2......................

any help on that?

[Rupesh Gujare]

Sonal,
   Looks like your kernel build is not in proper shape, Please clone kernel again. Post all logs here.
After following all steps, please post o/p of following command:-
  
  $git log

Hi Rupesh,

I hope all is going well:) Does this mean audio is now working? I've
haven't tried to build Android for a few weeks now. I'm going to try
it again today. Anything new I should be aware of before I begin?

Cheers,
Jay

[sonal]

Hi Rupesh,

I am using scripts/basic/fixdep binary from 2.6.25 kernel version..
and I am able to initiate the build..
but I wanted to know if there is any serious change in fixdep from
2.6.25 to 2.6.27 .. ?
because thats the only file causing build errors for me..

can i go ahead with this change?

sonal

[sonal]

Hi Rupesh,
When i use the file system built by me, mouse is not responding
properly. Every time i move the mouse , the GUI crashes...
Also, if i want to play some of my media files in the android, where
should i keep it ?
If i keep it in /system/ media/audio/, can i make him to find these
files?
I tried using Media Scanner, but that scans only sd-card it seems..

If i keep it in /system/ media/audio/,  can i make him to find these
files?
I tried using Media Scanner, but that scans only sd-card it seems..

Yes, it uses sd-card to scan media files.

$copy song.mp3 on your SD card partition1(/dev/mmcblk0p1), before inserting card into beagleboard.

$mount -t vfat /dev/mmcblk0p1 /sdcard
$setprop EXTERNAL_STORAGE_STATE mounted
$am broadcast -a android.intent.action.MEDIA_MOUNTED --ez read-only false -d  file:///sdcard

 

Although not sure if these steps are still workable. Please let us know status.
