I would like to build my i9000's kernel but there are problems
I've installed ubuntu 9.10.
As you know, i could download the source code from the web
In that there are codes for making kerne
and also there is a script, named build_kernel, which makes me be able to build the kernel.
At first, i installed sourcery toolchain and then modified the build_kernel.sh
Because the instruction said i should change toolchain's directory and prefix
And finally i built it writing './build_kernel.sh'.
It seemd to be working but there were so many errors
And the zimage file was small, it's only 2.1MB
I tried to flash that kernel but it made my phone go black.
Can anyone help me please?
What should i do?
How did some people make such great kernels? Sorry im newbie.

Hi all,
I recently began editing the Galaxy S kernel, from the downloadable open source package.
After some time I compiled my changes into a zImage. My problem is, it won't flash when i put it in the most recent PHONE_I9000XWJG5.tar.
Odin3 just hangs at Flashing zImage...
My zImage is about 2.5MB in size, and the original JG5 zImage is 4.6MB, so I guess I am missing something.
I think I am missing the modules (which you can also compile). But I'm not sure.
Does anyone know how to compile a working kernel for the Samsung Galaxy S?
Thanks in advance!
First:
Read here: http://www.cianer.com/androidg1/28-building-android-kernel-images
Then here: http://www.receptorblog.com/wordpress/howto-compile-a-linux-kernel-for-samsung-galaxy/
and finally here: http://forum.samdroid.net/f9/dev-vmware-image-build-i5700-kernel-2-6-29-android-2-1-a-984/
not update.zip,why?
In recovery, no sd update.zip option, how can I tune out?
I'm also trying to make a new kernel based on JM5.
My goal is to fix the BlueTooth issues.. I think i've found the problem in a kernel's .c file...
I'm following this link:

I'm downloading the GT-i9000 opensource ZIP from Samsung, but i don't quite understand where can i get the Android Toolchain....
Is It really 6GB as it says HERE ?
I wish there was a XDA-like tutorial for this
Hello friends,
I wanted to start kernel developing for the N910F. So i wanted to start compiling the original samsung sources.
Please excuse me, I'm pretty new to android/linux development.
I managed to get the kernel compiling, which gives me an output folder with some GB of stuff and as i could point out a zImage-file, which is hopefully the compiled kernel
To get my kernel working, extracted a stock boot.img with umkbootimg, which gave me a warning, that i can't repack the boot.img without using a modified mkbootimg executable.
A mkbootimg is included in the sammy-source so i used this to pack my zImage together with the extracted initfs.gz, resulting in a boot.img.
Which I flashed ofc, but the reason why i opened this thread is the result of this
The kernel is obviously not booting, it shows for maybe 0.5s the sammy logo and directly starts into download mode.
I guess it has something todo, how i pack my kernel. because i didnt even manage to unpack the stock kernel and repack it and get it booting.
So where is my mistake? Do i miss something?

Hi all !
After many years of "xda looting", i'm trying to contribute a little.
I'm a begginer, just learned 3 days ago how to use github ! So be cool guys, not a dev here.
Now i successfully compiled a Kernel, with addition of KCAL for now, but...
I got the Image.gz-dtb and i don't succeed in repacking it in a boot.img, if someone want to try, be my guest. (It's untested obviously, but compilation was without errors/warnings (we are close to stock for now.).
I tried mkboot, anykernel2, lazyflasher.... Always flash error, and i don't have time for the next few days, so if we could put a team together...
Here is the link to my compiled files (arch/arm64/boot) except dto folder. //Update to my Dev folder
Theorically you just have to rename, put it in a stock boot.img, "fastboot boot newboot.img" and test if Kcal is working with ex kernel manager, then more to come (governors, maybe OC, etc.)
Poke @d1ngh, you could help here after your work on twrp ?
Cheers guys, we could have our first custom kernel soon !

Defconfig used = defconfig daisy-perf_defconfig (with the kcal=Y addition not commited for now) // branch daisy-o-oss
Thank you very much! That´s what I waited for. Unfortunately 7zip says error: unknown compression method... Perhaps you can repack? Thx.
That is all we need ! A custom kernel thant can handle GSI !

Try it with android image kitchen (you first have to get the original bootimage from vendor/factory image, unpack it, exchange your kernel and repack it). recompiled official sources (with UBERTC) and it worked fine like that.

I've tried, maybe my image is bad, strange (I originally tried my stock source too, Google 4.9 toolchain, no luck). Can you test with the one in the link please ?
I will have access to my PC only next week...
Thanks a lot for your feedback !

Could you please share your build script ? Did you use an alternate defconfig ?
Learning here
EDIT : Which UberTC did you use ?

I used the original source code with some small changes (which are now included in official source) to make it compile.
Don't mind about the toolchain for the moment, gcc4.9 is most stable.
I don't have time trying this out atm, busy compiling los 15.1 but if you share exactly how you did it, (terminal log in pastebin and most importantly the exact errors, "doesn't work" doesn't help ) me or someone else might be able to help you (and you don't have to ask next time you get the error.
If you want you can start adjusting the lineage kernel, so i could build with los kernel which could save time towards working custom roms.
I successfully repack. But phone don't boot. (9.11 ROM)
Hello , can you help me with conpiling kernel source code? I tryed a lot of time but same issues , that could find same files.
I successfully repack image of kernel that you publish, but phone don't boot , they reboot in stock kernel(if i write fastboot boot boot.img) and I trying flashing image. They dont boot.
I vary want to create collection of custom kernel's on my device. And of course becouse i vary interested in this sphere, but new this.
Can you describe how you fix issues, or your compiling go without issues.
With best regards. Please help.

Thanks! O try to add kcal with this commits.
Yea, source for pie is not pushed. Xiaomi cant fix 8.1 kernel... Stock compiled kernel issue: wifi don't work...

Can you tell me what version of kernel you use whyle compile kernel? I tryed on new 9.11, but phone dont boot.
Maybe when you compile version be 9.10 or ealier.
becouse ramdisk and kernel image can conflict
I hope this can support settings for "display temperature" so that we dont need app for calibrating warmth or coolness of display
Current state:
Kernel builded.
Kcal included.
Wifi don't work , searching fix
