compiling Linux kernel for Samsung Galaxy 5 : compiled zImage doesn't work

I am trying to compile Linux kernel for my Samsung Galaxy 5 with full Netfilter support:
The phone specifications are:
Code:
Model number : GT-I5503
Firmware version : 2.1-update1
Baseband version : I5503DDJG5
Kernel version : 2.6.29-perf [email protected] #5
Build number : ERE27
I downloaded **GT-I5500_OpenSource.zip** and **GT-I5503T_OpenSource.zip** from opensource.samsung.com as they contain the required kernel trees for the samsung phone, and did the following steps:
I modified the .config file for enabling full netfilter support and then for **GT-I5500_OpenSource.zip**
Code:
[email protected]:~/GT-I5500_OpenSource_Kernel/kernel# ./make_kernel.sh
[email protected]:~/GT-I5500_OpenSource_Kernel/kernel# ARCH=arm CROSS_COMPILE=~/myandroid/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- make
Here i chose the toolchain from android source.
Now i got the required output, i.e.
Code:
CHK include/linux/compile.h
Kernel: arch/arm/boot/Image is ready
Kernel: arch/arm/boot/zImage is ready
Building modules, stage 2.
MODPOST 30 modules
[email protected]:~/GT-I5500_OpenSource_Kernel/kernel#
I copied this zImage in the phones sdcard, and tried to flash the kernel using **SGS Kernel Flasher**. The phone rebooted, but i could still see the old kernel version in the settings... And there is no netfilter(iptables) functionality.
I followed the same steps with **GT-I5503T_OpenSource.zip**
Code:
[email protected]:~/GT-I5503T_OpenSource_Kernel/kernel$ ./make_kernel.sh
[email protected]:~/GT-I5503T_OpenSource_Kernel/kernel# find . -type f -name ‘*’ -exec dos2unix {} \;
[email protected]:~/GT-I5503T_OpenSource_Kernel/kernel# make ARCH=arm CROSS_COMPILE=~/myandroid/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi-
and finally
Code:
CHK include/linux/compile.h
Kernel: arch/arm/boot/Image is ready
Kernel: arch/arm/boot/zImage is ready
Building modules, stage 2.
MODPOST 30 modules
[email protected]:~/GT-I5503T_OpenSource_Kernel/kernel#
But this kernel also doesn't work in the real device(Samsung Galaxy 5).
The third time, I copied the .config file from GT-I5503T_OpenSource.zip into the common folder, here the common folder has the kernel from
Code:
$git clone git://android.git.kernel.org/kernel/common
and did the same steps, I got zImage but it failed to work in the phone.
Please someone tell, what exactly am i doing wrong or do i need to go for kernel tree from some other sources. I did kernel compilation process for almost 5-7 times, but failed.
I tried to flash kernel from windows with fastboot, but that also didn't work...
please someone help... Thank you!!!

[Q] envsetup.sh device profile

As I'm sure many will know Telechips do not release their SDK or linux BSP to people without buying and expensive development board and commitment to buying vast amounts of chips.
I have a cx-01 and the device is crippled on kernel features and force loading of kernel modules is disabled by default.
cnxsoft had some information regarding the kernel source release, but without framework recompile it won't boot.
Android source will give me the envsetup.sh, but misses the telechips profile out.
I wondered if anyone has the telechips 8923 folder in WORKING_DIRECTORY/device -if so where did you get it and can I have a copy.
Failing that I have a decompiled system image for the cx-01 and a copy of telechips 8902 profile-I wondered if it is possible to create a working tcc8923 with these?
I notice back in January nobody had a working custom kernel for this processor- am I barking up the wrong tree?

To build Android from source for a new device, you need to set up a board config and its makefiles. This is generally a long and tedious process. Luckily, if you are only building recovery, it is a lot easier. From the root of your Android source directory (assuming you've run envsetup.sh), run the following (substituting names appropriately): ( I gues envsetup.sh means running: 1: . build/envsetup.sh
2: lunch 3: 1 (my choice) 4: make m805_892x my tablet type)
build/tools/device/mkvendor.sh device_manufacturer_name device_name /your/path/to/the/boot.img
For my Tom-Tec 7 excellent, the command will go as follows :
Code:
build/tools/device/mkvendor.sh YG m805_892x ~/boot.img
> ore: build/tools/device/mkvendor.sh YG m805_892x ~/recovery.img
the later needed kernel is in recovery.img it seems.
Please note that m805_892x is the device name..... Only use "~/boot.img" if you have the boot image in your home directory. Or else please specify the correct path.
You will receive the confirmation "Done!" if everything worked. The mkvendor.sh script will also have created the following directory in your Android source tree:
manufacturer_name/device_name
YG/m805_892x
Sow get youŕe recovery.img and use that to get WORKING_DIRECTORY/device/YG/m805_892x
Device name is in build.prop
Try this link to see what it makes from the board config and its makefiles http://builder.clockworkmod.com
Personally i´m still stuck making a cwm recovery thats works 100% on my tablet.
I build from CWM source.

compile google sources with samsung ICS

Hi,
i'm trying to compile google sources version 4.0.4 with samsung sources from opensource samsung
From samsung sources i've only used the platform files. I've done all the steps that are in the platform readme:
How to build Mobule for Platform
- It is only for modules are needed to using Android build system.
- Please check its own install information under its folder for other module.
[Step to build]
1. Get android open source.
: version info - Android gingerbread 4.0.4
( Download site : source android)
2. Copy module that you want to build - to original android open source
If same module exist in android open source, you should replace it. (no overwrite)
# It is possible to build all modules at once.
3. Check module is in 'build\core\user_tags.mk'
If not, you should add your module name in it.
ex1) external\libjpega : Write "libjpega \" into "build\core\user_tags.mk"
ex2) external\libexifa : Write "libexifa \" into "build\core\user_tags.mk"
4. In case of 'external\bluetooth',
you should add following text in 'build\target\board\generic\BoardConfig.mk'
BOARD_HAVE_BLUETOOTH := true
BOARD_HAVE_BLUETOOTH_BCM := true
5. excute build command
./build.sh user
The command user was ./build.sh eng
Before running this command i've installer jdk 6 and follow the steps from android initializing
the ./build.sh eng run with success and after this i've run the make.
Some hours later i've got a new folder "OUT", inside there is a system folder but i've tryed to flash this folder with odin
and no success.
What am i doing wrong?
Thanks.

Trying to build the kernel + modules?
If i understand what your trying to do, Install new kernel and modules?
!!!!!Before you try this, do some research for your device and make sure this is the correct action!!!!!
you are looking for a file called: zImage
It should be in <build path>/arch/arm/boot/
To install the new kernel, you put your device into fastboot
Code: adb reboot-bootloader
Then you can install the new kernel:
Code: fastboot flash zimage /<path to your zImage file>/zImage
Then you can boot your device and manually copy over the modules.
Note: I didn't see in your steps where you mentioned configuring the kernel, are you doing this?

Thanks for your reply.
the kernel i've already compiled like you mentioned and it is ok i've flashed the zImage.
But there is another part that is the platform module that corresponds to the system.
When you have a Rom there are 3 things inside:
- boot.img that has the zImage (kernel)
- meta-inf
- system
i'm changing the code in one file that corresponds to the nfc part and them compile the samsung sources
and google sources to get that system.
after compile the is one folder out that has system.img but i can't flash this .img file the mobile phone gets like a stone :S
All Black!

Please describe the process you are using to flash the system.img.
Have you though about just copying over the modified files?
Also, if you could create a step by step list of your process, maybe we can figure out what's going wrong.

i've compiled the google+samsung sources and this created the system.img.
Then i used Heimdall to choose only system to flash and It didn't work.
i've tryed also to change only the nfc.apk file put it in the app folder tryed to flash the ROM (in this case from Cyanogenmod) and it didn't work.
Thanks.

have you tried to remove and install your nfc.apk using adb rather than trying to flash the entire rom? I would think all you need to do is mod the kernel, flash the kernel, then copy over any modules and replace the nfc.apk.

[Q] Hp slate 21 Kernel Compilation

Hi, I am looking to compile the hp slate 21 kernel
I Have the source code which I took from Hp Open Source at this link:
https://h20392.www2.hp.com/opensource/product.jsp?cat=100&e=true&fam=Desktop+PCs&prd=E2P18AA
The problem is that i don't know 3 things because the readmeFile inside the kernel is the Linux one and is not specific for the hp kernel:
1: The specific Toolchain required to build this kernel
2: The Configuration file for the HP slate 21 ( I took the one from /proc/config.gz config ) from the tablet
3: Which ARCH to choose arm,x86,ia64 etc...
ANY information like samsung kernel gives would be great
I know how to build Samsung kernels because in the readmefile that looks like this, there is enough information to know what to do:
HOW TO BUILD KERNEL FOR GT-P5113_XAR
1. How to Build
- get Toolchain
download and install arm-eabi-4.4.3 toolchain for ARM EABI.
Extract kernel source and move into the top directory.
$ export CROSS_COMPILE=/opt/toolchains/arm-2010q1/bin/arm-none-linux-gnueabi-
$ make android_espresso10_omap4430_r02_user_defconfig
$ make
2. Output files
- Kernel : Kernel/arch/arm/boot/zImage
- module : Kernel/drivers/*/*.ko
3. How to Clean
$ make clean
4. How to make .tar binary for downloading into target.
- change current directory to Kernel/arch/arm/boot
- type following command
$ tar cvf GT-P5113_XAR.tar zImage

Thank you sir.Great guide really and very helpful,but this guide is for CM,i am downloading cm-12.1 nut you know it takes long time since my connection is pretty slow.In the meanwhile i am trying to build my existing AOSP wish i've already downloaded.
let's forget about this tablet.
I also downloaded the GT-I9300 files from opensource samsung site "GT-I9300_JB_Opensource.zip" and here is what it includes :
2 folders : Kernel , Platform.
2 files : README_Kernel.txt , README_Platform.txt.
The Platform folder contains :build,external,framework,vendor and build.sh.
Inside README_Kernel there is :
1. How to Build
- get Toolchain
From android git server , codesourcery and etc ..
- arm-eabi-4.4.3
- edit Makefile
edit "CROSS_COMPILE" to right toolchain path(You downloaded).
EX) CROSS_COMPILE= $(android platform directory you download)/android/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-
Ex) CROSS_COMPILE=/usr/local/toolchain/arm-eabi-4.4.3/bin/arm-eabi- // check the location of toolchain
$ make arch=arm m0_00_defconfig
$ make
2. Output files
- Kernel : arch/arm/boot/zImage
- module : drivers/*/*.ko
3. How to Clean
$ make clean

# It is possible to build all modules at once.
3. You should add module name to 'PRODUCT_PACKAGES' in 'build\target\product\core.mk' as following case.
case 1) e2fsprog : should add 'e2fsck' to PRODUCT_PACKAGES
case 2) libexifa : should add 'libexifa' to PRODUCT_PACKAGES
case 3) libjpega : should add 'libjpega' to PRODUCT_PACKAGES
case 4) KeyUtils : should add 'libkeyutils' to PRODUCT_PACKAGES
ex.) [build\target\product\core.mk] - add all module name for case 1 ~ 4 at once
PRODUCT_PACKAGES += \
e2fsck \
libexifa \
libjpega \
libkeyutils
4. excute build command
./build.sh user

make -j$CPU_NUMBER PRODUCT-generic-$TARGET_BUILD_VARIANT
So i ignored build.sh and cd my jellybean source and did make -j8 PRODUCT-generic-eng.
it built sucessfully , now i have inside out/target/product/generic/ system.img and ramdisk.img and userdata.img.
But here is the question : Why Samsung does build it this way?why does not do it the normal way like CM does?
As i know that the generic build is for emulator right? so why samsung build a generic build?
Now after i have those imgs and the kernel Zimage , am i ready to go?am i on the right track?
If so ,how to flash the device?
I am sorry for bothering , thank you for your help.
