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][ROM] My custom rom fails Samsung GTi9100

Hi,
I am a new beginner of android. I am trying to rebuild the kernel with profiling support for Samsung galaxy s2 (GT-i9100). After flashing my custom rom to my phone, my phone does not work.
This is how I do it:
1.Downloaded the image I9100XXLP6_I9100OXXLP3_OXX and flashed my galaxy s2 mobile using odin software. now my Galaxy s2 works fine with ICS build (kernel version - [email protected] #3, Ardroid version - 4.0.3).
2. Downloaded the samsung galaxy s2 source code GT-I9100_ICS_Opensource_Update8.zip from opensoure.samsung.com and cross compiler arm-eabi-4.4.3.
3. Use the initramfs from github (Since I am a new user of this forum, I can not post outside link here; I google with "arighi/initramfs-gt-i9100.git" and use the first link)
4. Through "make menuconfig" to enable the profiling support and configure the initramfs source path as specified at step 3.
5. After compiling, I can get the custom zImage of size about 8 MB
6. Then I use "tar -cvf mykernel.tar zImage" to generate my custom rom; and then flash it to my phone through odin.
7. Now my phone boots with a kernel panic upload mode screen and my phone doesn't work.
My question:
1. Does the initramfs cause the problem? If it is, where can I get the matched initramfs for the kernel source code?
2. Is there anything wrong in my above steps?
I would be very appreciated if someone could help me.
Thanks.

[Solved] Kernel from source on 4.2.2

Hi,
I'm currently trying to build a kernel for my GT-P5110. I have a stock Android 4.2.2 which I downloaded from sammobile. I also downloaded the kernel from Samsung Open Source. I've use split_bootimg.pl to get the ramdisk from the boot.img and mkbootimg to make a boot.img from my zImage build successfully and the ramdisk. The problem is, when I flash my boot.img, I get stuck on the Samsung Galaxy Tab 2 logo even if I use the android_espresso10_omap4430_r02_user_defconfig which is suggested by Samsung.
Is there anyone able to sucessfully flash this kernel on his device?
Update: It seems like the defconfig file included in the Samsung Open Source contains some error.
If you want a working defconfig file use this one: http://forum.xda-developers.com/showpost.php?p=37685672&postcount=12

[Q] Installing USB Ethernet Adapter drivers

I recently got an ASIX AX88179 USB 3.0 to Gigabit Ethernet adapter for my Android device running CyanogenMod based on Android 5.1.1 and the 3.4.* kernel.
The drivers for the device are provided as source code and are available:
http://www.asix.com.tw/FrootAttach/driver/AX88179_178A_LINUX_DRIVER_v1.14.2_SOURCE.tar.gz
ASIX represents that the drivers are "For Android 1.x/2.x/3.x/4.x/5.x, Linux kernel 2.6.25 and later".
I attempted to compile the drivers using the CyanogenMod-included Terminal emulator App, but could not get anything to compile. It seemed that the "make" command or tool is not recognized.
I found a note in the drivers source readme file:
Code:
Prepare to build the driver, you need the Linux kernel sources installed on the
build machine, and make sure that the version of the running kernel must match
the installed kernel sources.
I found kernel sources on https://www.kernel.org/ . How do I make use of the kernel sources?
The version 3.4.* kernel is frequently updated. Should I be recompiling the driver with new, updated kernel sources every time a new kernel version is installed?
Must the drivers be compiled on the system they are to be used on?
Is there a better way to handle driver preparations or acquisitions?

Unable to load wifi module for ASUS ROG Phone 1

Specifications:
Phone: ASUS ROG 1
Model Number: ASUS_Z01QD
Android version : 8.1.0
Firmware: WW-15.1630.1907.98
Kernel Version: 4.9.65-perf
I have an ASUS ROG 1 Phone. It came with Android 8.1 and firware version WW-15.1630.1907.98. I took the kernel source code from ASUS site. Source code version: <new user on XDA hence unable to post the src code link.>
Was able to build successfully and flash to the phone. Rooted the phone following to that. The problem is that the wifi wasnt working after flashing the new kernel .
1. I checked the modules loaded lsod, from adb and it didnt show the wil6210.ko loaded.
2. I tried insmod /modprobe wil6210.ko and was constantly getting the following errors:
a. disagrees about version of symbol module_layout android kernel
b. required key not available .
c. No such file or directory.
3. I tried building the kernel with the SIG flags disabled in the .config file and flashed to the phone. Yet ended up getting errors like no such file or directory and required key not available.
Any help will be really appreciated.

You need to rebuild the Wi-Fi module against the source that you compiled then flash it. Alternatively, you can try building the Wi-Fi source into the kernel image but that is usually broken or you can force the module to load by whitelisting it in kernel/module.c (there are commits floating around that allow this) but it can open up a security vulnerability.

Thanks for your reply.
The source code I downloaded from the ASUS website, the wifi module code was a part of it. So whille building the kernel the module <wil6210.ko> also got built along with it.
So the wifi module did get built against the same source.
