[sivam]

Hello All,
I am looking to port android in our custom i.mx31 board, i would
like to know where i can get the Android patch for the i.MX31 Any
pointers is greatly appreciated.

Thanks

Hi,

you should get the Linux Source PDK 1.3 from freescale (for the
patched kernel and bootloader) and follow the instructions from
http://elinux.org/Android_on_OMAP. If you don't need the power stuff
from Android, you can leave them away while compiling the kernel, that
makes the porting process a bit faster. The new 0.9 release of Android
requires additionally the ashmem driver (Android's Shared Memory
Subsystem), which is not yet listed on the webpage from above.

Good luck on porting. :)

Hi Markus,

Thanks for reply
We are trying to port Android on ARM11(imx31) using following think:

--->android-sdk-linux_x86-0.9_beta root file system
--->linux-2.6.25-android-0.9_r1.tar.gz android kernel patch
--->linux-2.6.22.6 kernel (Get the Linux Source from freescale LTIB)
----> android file system in SD-card (ext2 file system)

i would like to know how i can change the below files or driver
kernel/power/process.c
kernel/printk.c
drivers/input/evdev.c
fs/proc/proc_misc.c
fs/proc/task_mmu.c
include/net/tcp.h
kernel/sched_fair.c

kernel/sched_fair.c (not present in linux-2.6.22.6)
mm/filemap.c

Lots of difference between 2.6.22 and 2.6.25 kernel(means not possible
to apply manually all the android changes into linux-2.6.22 kernel)

Any help will be highly appreciated. Thanks in Advance.

Thanks & Regards,

HI,

the key is to use the tool diff to create a patch from a clean kernel
and the Android kernel (same kernel versions!), remove all stuff from
the patch file that you will not need (qemu and goldfish related
things, yaffs2 things only if your freescale kernel provides already
yaffs2 - and you need this only, if you want to use it).
Then apply your patch with the tool patch. You will get a report,
which things were applied by the automated mechanism, and which things
went wrong. Those which went wrong are left for manual patching: Jump
to that point in your patch and try to apply it to the kernel source.
If files are missing, you can try to skip them, but sometimes this
code is left in other files. Sometimes you have to guess, how to
adjust the Android code to your kernel.
I managed to use a kernel without the fair scheduler, so you can skip
it.

Most stuff is portable, I used for a long while kernel 2.6.19.2 as
base. Just use diff and patch as base of your work, a kernel is too
big for manual patching. You could also get the kernel 2.6.24 on the
freescale homepage, makes things easier.

Please check the internet for the usage of patch and diff, you will
find plenty of tutorials.

Hi all, I'd also be interested to get android working on the i.mx31.

Deepak, did you have any luck?

Kind Regards,

Hi Markus

Thanks a lot for your response.
I have already ported the android M3 SDK on IMX31 board using 2.6.22.6
kernel(get the android specific change from 2.6.23 android kernel)
Presently i am working on porting android beta kernel onto IMX31.
I would like to know default android kernel configuration for inital
IMX31 porting (Y/N):

CONFIG_HAVE_LATENCYTOP_SUPPORT
CONFIG_PANIC_TIMEOUT
CONFIG_ASHMEM
CONFIG_DEVMEM
CONFIG_LOW_MEMORY_KILLER
CONFIG_QEMU_TRACE
CONFIG_SWITCH
CONFIG_ANDROID_RAM_CONSOLE
CONFIG_ANDROID_POWER
CONFIG_ANDROID_LOGGER
CONFIG_ANDROID_TIMED_GPIO
CONFIG_ANDROID_BINDER_IPC
CONFIG_ANDROID_PARANOID_NETWORK

I have taken linux-2.6.22.6 kernel, then applied beta(2.6.25) patches.
i am not clear, what should i do for some android specific change
(presently skip).

pls share your experience on this....

i would like to know where i can get the kernel 2.6.24 for the
i.MX31.
I am not able to find this kernel version on freescale site.

[deepak singal]

Hi Markus

I have get the Linux Source PDK 1.3 from freescale site and now start
with 2.6.24 kernel.

[Sivam MG]

Hi Deepak,
    Do you have the working i.MX31 full kernel available with android patch ?. Any pointers from where i can download ?.

Let me know

Hello Deepak,

I'm also starting with the 2.6.24. I'm in the process of trying to
make a patch file for the I.MX31 how is your progress going?

My basic approach so far is this:

linux-2.6.24-freescale-imx31 -> working kernel on the imx31
linux-2.6.25-android-0.9_r1 -> kernel from google site.

I run:

diff -Naur linux-2.6.24-freescale-imx31 linux-2.6.25-android-0.9_r1 >
original.patch

This produces a diff file that is about ~300000 lines long!!!!

Is this the same approach everone else is taking?

Kind Regards,

Ben

Hi all,

Presently i am looking with the 2.6.22.6 and 2.6.24 IMX31 kernel.
My basic approach so far is this for 2.6.22.6 kernel :

Download linux-2.6.25-android-0.9_r1 android specific kernel from
Google site.
Download linux-2.6.25 kernel.
diff -Naur linux-2.6.25/ linux-2.6.25-android-0.9_r1/ -->
android.patch
Get the working kernel linux-2.6.22.6 on the freescale imx31 LTIB.
Apply our board specific change.
Remove all stuff from the android.patch file that will not need
(goldfish related things, yaffs2 things because freescale kernel
provides already yaffs2).
Then apply android.patch with tool patch. On applying the patch, it is
being observed that some files are applied by the automated mechanism,
and some things went wrong. Those which went wrong are left for manual
patching.
Jump to that point in my patch and try to apply it to the kernel
source manually.

I am not able to make android power driver. I think lots of changes
required in 2.6.22.6 kernel for android power driver.
i would like to know any one able to compile(android_power driver)
linux-2.6.22.6(IMX31) kernel for android.
Please share your experience on android power driver(linux-2.6.22.6
kernel) .............

Any help will be highly appreciated.

Thanks & Regards,
Deepak Singal

Hi,

I can use Android now on the i.MX31. I am using the 2.6.24 Freescale
kernel and a clean Android patch from 0.9 beta. The new Android
version
0.9 requires the android power driver to get the keypad working.
Currently, I try to fix the touchscreen.

@Ben: Your patch creation process is wrong. You must create the patch
by checking the Android 2.6.25 kernel against a clean 2.6.25 kernel,
not the patched
freescale kernel. This
will give you a much smaller patch (without changes between 2.6.24 and
2.6.25).

For the kernel 2.6.24, the power stuff needs also some changes/
extentions to the
Linux kernel, but it is mostly straight forward.

@deepack: The ltib configuration tool sets all the parameter/
configurations needed for the
freescale patches. Just add the the Android driver, including the
ashmem driver.

Hi all,

I am trying to Port beta SDK Android kernel on ARM11(imx31) using
freescale linux-2.6.22.6 kernel source.
Using below android kernel configuration--->
#
# Android
#
# CONFIG_ANDROID_RAM_CONSOLE is not set
CONFIG_ANDROID_POWER=y
CONFIG_ANDROID_POWER_ALARM=y
CONFIG_ANDROID_POWER_STAT=y
CONFIG_ANDROID_LOGGER=y
# CONFIG_ANDROID_TIMED_GPIO is not set
CONFIG_ANDROID_BINDER_IPC=y
CONFIG_ANDROID_PARANOID_NETWORK=y

CONFIG_ASHMEM=y
CONFIG_LOW_MEMORY_KILLER=y
# CONFIG_QEMU_TRACE is not set

First boot into my normal file system (using jffs2 file system) and
then switch to Android file system and start Android init script.
imx31#mount /dev/mmcblk0 /sd/ (mount sd card) (ext2 file system)
imx31#./a.sh

/*************a.sh***************/
#!/bin/sh -x
echo "Starting Android..."
fsck.ext2 -pv /dev/mmcblk0
mount /dev/mmcblk0 /sd
rm -f /sd/usb/tmp/*
umount /proc
umount /sys
mount -t proc proc /sd/usb/proc
mount -t sysfs sysfs /sd/usb/sys
sync
export PATH=/sbin:/system/sbin:/system/bin:$PATH
export LD_LIBRARY_PATH=/system/lib
export ANDROID_BOOTLOGO=1
export ANDROID_ROOT=/system
export ANDROID_ASSETS=/system/app
export ANDROID_DATA=/data
export EXTERNAL_STORAGE=/sdcard
export DRM_CONTENT=/data/drm/content
umask 000
chroot /sd/usb /system/bin/sh
/********************end_a.sh***********/

After that android shell shown in the console than start init
using----->
#./init &

The below messages keep printing on the console:
# init: cannot open '/logo.rle'
init: service 'console' requires console

And the android logo on the LCD keeps blinking and stop after some
time.
Have any of you faced the following problem?

I'm comparing IMX31 board logcat with emulator logcat message (note
the below points)

-------->***** ERROR! android_os_fileobserver_observe() got a short
event!
-------->W/PackageManager( 1660): System package

don't know who it is
---------> /sys/class/power_supply directory not present in my android
file system (already enable android power config)

Please any one explain all the above point (compare with emulator
logcat).

Hi,

don't ask me why, but I have to start with strace enabled. But you get
useable speed by sending the output to /dev/null or files. So try
booting by
/system/bin/strace -ff -F -tt -s 200 -o /dev/null /init
- it works for me.
The missing logo file is normal, I think, it's the same for me.
You need to patch the i.mx31 framebuffer stuff to solve the
flickering, see http://groups.google.com/group/android-internals/msg/f37bee0916c65b36

bye
Markus

Hi Markus,

Thanks for pointing out my error. I've successfully made a patch using
a vanilla 2.5.25 and the android 2.6.25 kernel. The patch is around
30,000 lines long before the removal of the goldfish, qemu and other
stuff.

How many lines roughly is your working patch file so that I know i'm
heading in the right direction?

Kind Regards,

Ben

P.S. Sorry about my multiple postings before, the refresh button is
evil!

[Ben]

Hi Markus + Deepak,

Glad that progress is being made. I'm currently in the process of
chopping down my 30,000 line patch file to a more managable size.

Is it possible to simply apply the patch as-is? Can i not then simply
go through the kernel configuration disabling / enabling the android
bits i need?

@Deepak - Why are you using the freescale 2.6.22 kernel version? why
not the 2.6.24 version that both myself and Markus are using?

Also, do you guys have any idea as to how big the patch file will be
after initial removal of goldfish etc? Just so that I know what to aim
for.

Kind Regards,

Ben

Hi Ben,

you will have to do some smaller things manually, but most of it is
rather easier as the automatic process will not recognize additional
lines from the freescale patches. Only the Android power stuff needs
some more effort, but it is necessary for Android 0.9 beta. Yes, you
can add the Android stuff step by step and fix the new parts, if
necessary.

I am not at work right now, so I cannot give you exact numbers/
filesizes, but I think that my not revised patch was about 1 MByte,
the revised one about 200-300 kByte.

bye
Markus

Hello Markus,

My patch file seems to be in the order of 200-300 kByte. :-)

According to my research, the (changed) files below seem to be
sufficient to run Android on real HW. Could you look through your
patch file and tell me if there are any that I'm missing?:

arch/arm/Kconfig
arch/arm/kernel/process.c
arch/arm/kernel/signal.c
drivers/android/alarm.c
drivers/android/android_gadget.c
drivers/android/android_kernel_debug.c
drivers/android/android_kernel_debug.h
drivers/android/binder.c
drivers/android/Kconfig
drivers/android/logger.c
drivers/android/Makefile
drivers/android/power.c
drivers/android/ram_console.c
drivers/android/timed_gpio.c
drivers/input/evdev.c
drivers/Kconfig
drivers/misc/Kconfig
drivers/misc/lowmemorykiller/lowmemorykiller.c
drivers/misc/lowmemorykiller/Makefile

include/linux/android_timed_gpio.h
include/linux/binder_module.h
include/linux/binder_type_constants.h
include/linux/logger.h
kernel/power/process.c
drivers/Makefile

Does this match up to your patch file?

My patch file is as follows:

+ The memory driver provides two character devices, mem and kmem,
which
+ provide access to the system's memory. The mem device is a view of
+ physical memory, and each byte in the device corresponds to the

rather

whats this error: PANIC:handle_group_exit ???
Due to below kernel configuration?????

#
# Kernel Features
#
CONFIG_PREEMPT=y
CONFIG_HZ=100
CONFIG_AEABI=y
# CONFIG_OABI_COMPAT is not set
Any clue to track the problem ???

@Ben--- Hi,
Presently our IMX31 board support only linux-2.6.22.6 and linux-2.6.19
kernel.
Patch size approx. 350Kbyte (skip goldfish, yaffs and some android
specific change)


Warm Regards,
Deepak

[Markus]

Hi

@Ben: On the first sight, your patch looks fine. I don't have access
to my Android stuff right now, so I can't check, if you have all files
with patches. Anyway, if you like, you can remove those code parts,
where something is done with QEMU or Goldfish in the rest of your
code, but this is not necessary. Just give it a try :)

@Deepak: Did you install a strace? It is not included in Android, but
somebody posted a link here in the group (don't know the link out of
my head, sorry). I think I had the same problem with the 2.6.19.2
kernel so I decided to upgrade to 2.6.24. I fear that I can't tell
you, which kernel module/part is not working, so you have to check for
yourself, e.g. by kernel debugging. Or just upgrade to 2.6.24, this
kernel is not that hard to patch for Android.

bye
Markus

[Ben]

Hi

@Markus, thanks for the response. I'm making headway into the android/
power.c problem. As far as I cant tell the correct approach is to
patch the 2.6.24 kernel specifically the files:

lib/kobject.c
include/linux/kobject.h

To have the functions:

kobject_init_ng, kobject_add_ng, and kobject_init_and_add

[details from http://linux.derkeiler.com/Mailing-Lists/Kernel/2007-12/msg00659.html]

I'm having trouble at the moment as I can't seem to apply the patch
file. I'm having to make the changes by hand.

If you have any pointers / comments please let me know.

@ Deepak - Out of interest, what development board are you using? I'm
using the freescale I.MX31 ADS

Kind Regards,

Ben

[deepak singal]

Hi Markus,

Presently i'm using Linux-2.6.22.6 freescale kernel source.

Download strace from below link-------->
http://ortegaalfredo.googlepages.com/android

and run android init using below command------->

# /system/bin/strace -ff -F -tt -s 200 -o /dev/null /init

whats this error: PANIC:handle_group_exit ???

please check below link also for this error---->
http://groups.google.com/group/android-internals/msg/97973de61f5a86ee

Any clue to track the problem ??

Any ideas? I've love to get something appearing on the framebuffer by
the end of the day!

Hi Again,

Right,

I've compiled in the ASHMEM driver and got much further. This time
when i run init, I get:

=========================================================

# ./init &

# init: cannot open '/logo.rle'

sh: can't access tty; job control turned off
#
=========================================================

I also get the "android_" text on my lcd display. However it just
seems to stop there. Is the "can't access tty: job control turned off"
the problem?

Any help would be greatly appreciated.

Kind Regards,

Ben

Hi ,

Can anyone please tell complete android kernel configuration .config
file (linux-2.6.24+android patch) for IMX31ads.

Warm Regards,
Deepak

[Ben]

Hello Deepak,

Thanks for the info regarding kobject and for the info about the
keyboard, However I'm using a small keyboard PCB attached to my
development board. Are you suggesting that I use a USB keyboard?

Kind Regards,

Ben

[deepak singal]

Hi,

I've compiled both ASHMEM and Android POWER driver. When i run init, I
get:

# ./init &
# init: cannot open '/logo.rle'

init: service 'console' requires console

android_power_suspend: 478940297684
android sleep state 0->2 at 478940297684
android_power_suspend: enter suspend
Stopping tasks ... done.
Suspending console(s)
=====================================

Get the "android" text on my lcd display and after that "android
logo".
However it just seems to stop after printing above messages.
Please share your experience on above messages.

Ben@
I dn't exactly know for PCB but m using USB keyboard....and for M3 usb
keyboard wrk fine.
Please share your kernel configuration for android (.config file)
I think m missing somemthing in kernel configuration.


Warm Regards,
Deepak

[Ben]

Hello Deepak,

Below is my complete .config file for the 2.6.24 kernel. It could be
wrong so don't assume it's correct! I'm wondering if my keyboard
problem is associated with the power driver. I don't get any messages
like you're getting about 'android_power_suspend' after running init &
but I'm sure that ANDOIRD_POWER = y in the kernel. Any ideas?

Hi Ben,

I am using below android kernel configuration------>(change after
applying android patch)

=================================================================

#
# Android
#
# CONFIG_ANDROID_RAM_CONSOLE is not set
CONFIG_ANDROID_POWER=y
CONFIG_ANDROID_POWER_ALARM=y
CONFIG_ANDROID_POWER_STAT=y
CONFIG_ANDROID_LOGGER=y

# CONFIG_ANDROID_TIMED_GPIO is not set
CONFIG_ANDROID_BINDER_IPC=y
CONFIG_ANDROID_PARANOID_NETWORK=y

CONFIG_ASHMEM=y

CONFIG_LOW_MEMORY_KILLER=y
# CONFIG_QEMU_TRACE is not set

# CONFIG_SWITCH is not set

CONFIG_HAVE_LATENCYTOP_SUPPORT=y
CONFIG_PANIC_TIMEOUT=0

#
# TPM devices
#

# CONFIG_TCG_TPM is not set
CONFIG_DEVMEM=y

=============================================

I think this problem (message coming) is not associated with the any
type of keyboard driver.
I'm using below things--->
----> check output on LCD and init message on console.
----> Without connecting any usb mouse or keyboard on IMX31 board.

this problem associated with console ????
I'm using /dev/ttymxc0 for console and /dev/tty0 for LCD(frame
buffer).
init not able to handle kernel console???

Warm Regards,
Deepak

Hi Ben,

When I run init with android configuration ANDROID_POWER_STAT=y I get:
=============================================

# ./init &
# init: cannot open '/logo.rle'
init: service 'console' requires console
android_power_suspend: 478940297684

android sleep state 0->2 at 478940297684

android_power_suspend: enter suspend
Stopping tasks ... done.
Suspending console(s)

============================================

Get the "android" text on my lcd display and after that "android logo

blink on lcd".
However it just seems to stop(not display android logo on LCD) after
printing above messages.

When i run init with android configuration ANDROID_POWER_STAT=n I get:
============================================

# ./init &
# init: cannot open '/logo.rle'
init: service 'console' requires console

==============================================

Get the "android" text on my LCD display and after that "android logo
" blinking continuously displaying on LCD.

Please share your experience on above 2 different configuration case.

Warm Regards,
Deepak

Hello Deepak,

I think you're missing one declaration in kobject.h I had to add it...

extern struct kobject * __must_check kobject_create_and_add(const char
*name, struct kobject *parent);

Otherwise, when compiling i get an error that there has been an
implicit use of function 'kobject_create_and_add'.

Seems to be working okay now!

Ben

P.S.

I don't suppose you have any idea of how to configure android proxies
when using real hardware?

[deepak singal]

Hello Ben,

I'm not using extern struct kobject * __must_check

kobject_create_and_add(const char *name, struct kobject *parent);

decleration in kobject.h file.
Without this I'm able to compile my kernel with android power driver
enable.


Warm Regards,
Deepak

Hi Ben,

When i run android rootfs init with android configuration
ANDROID_POWER_STAT=n I get below logcat messages using logcat
command.

Get the "android" text on my LCD display and after that "android logo"

displaying on LCD.
Please compare with your real hardware logcat.
I'm missing something?? Any idead???
How is your progress going on?
Any luck for android lock screen or main screen ??
