[GUIDE]Building a Kernel from source{Mediatek}

[pchatzop]

Hello guys, thank you for your awesome work. I need a kernel to make a friend's phone work correctly with kitkat , the thl w200s. I found some kitkat kernel sources(all credits go to snowcatPDA from 4pda forums) here: https://yadi.sk/d/nQBTPzucjFkSm . Would someone be so kind to compile them, since i have no idea on android development and would probably mess it up? Thanks.

u first need setup ur defconfig, then execute the menu config<br />
<br />
<br />
<br />
then execute menuconfig<br />
<br />
<br />
<br />
change all u need and close window. then create a zImage<br />
<br />

Bro this way doesn't work on my source. It's in ALPS form.

No one can help me with zImage dont working?

 

[Goayandi]

Thank you very much Your Guide helped me a lot. But i do not quite understand how to upstream the kernel-source to the latest linux-patch.
I tried to download all patches from 3.4.67 (my stock kernel-version) to latest 3.4.111 from kernel.org. As i learned from a guide on Xda, i have to move these patches to kernel-folder (does that mean, i have to use the "kernel"-folder in root-directory or the mediatek-folder?).
There i used this command:

$ patch -p1 < patch-3.4.68

Is that right? Or how to apply these patches?

SOLVED.
I found this guide http://www.pro-linux.de/artikel/2/1572/3,aktualisieren.html .

@MasterAwesome

I see that you didn't ever use tools like makeMtk. It's because the guide is out of date and it wasn't necessary at the time, or is there any other explanation?

Well, I had to download the entire ALPS build environment.
Then download your devices kernel and build it using build.sh , after configuring the environment in the kernel dir.
Afterwards copy the generated kernel...bin file into the baoxue_mytqe-master/kernel/ dir and rename it to kernel_baoxue.bin
then run
./target_build bootimage
you will get your boot.img in /baoxue_mytqe-master/out/target/product/baoxue/boot.image
that's all, I did , but i'll have to look into it deeply to understand what is going on.
Any am a little dissappointed that nobody showed how to do this, or even offered to help.
But I guess the best way is the hardway , compiling it a hundred times, only to figure out that arm-android-eabi doesn't work I found this after trying the original arm-eabi-
If you get s bootloop, try building with the stock .confi from the downloaded source then proceed.

Bro, my source is also ALPS (Lenovo A536). Can you teach me how'd you set up the build enviroment?

[kenkitt]

First you need a 64bit linux distro, download the kernel from the vendor and the targets toolchain.
then follow this guide http://xdaforums.com/showthread.php?t=2754513

Instructions are compatible for any devices.

Check line 44 in your Makefile.build file. It looks like you may have added an extra "/" between "platform" and "kernel". That may be why it can't find the directory with your makefile in it.

[prateetsingh]

That is because the Environment variable "ARCH_MTK_PLATFORM" is not set. export it via the terminal. something like

export ARCH_MTK_PLATFORM=MT****

since the KConfig will specify the directory and drivers it will build using this variable

config ARCH_MTK_PLATFORM
  string
  option env="ARCH_MTK_PLATFORM"
[B][I][I]source "../mediatek/platform/$ARCH_MTK_PLATFORM/kernel/Kconfig/Platform"
source "../mediatek/platform/$ARCH_MTK_PLATFORM/kernel/Kconfig/Kernel"
source "../mediatek/platform/$ARCH_MTK_PLATFORM/kernel/Kconfig/Board"
source "../mediatek/platform/$ARCH_MTK_PLATFORM/kernel/Kconfig/Drivers"[/I][/I][/B]

You can google search "kernel source for the NO.1 D6".

Is there a chance that No.1 will link me to the kernel ?

All I found were these links

You can probably try asking the company on the site for the kernel source.

Hi,

I see that NO.1 D6 is using android 5.1 with mtk6577,
so isn't it just a matter of building mediatek kernel source for mtk6580 ?
I found mtk git for 5,1 here:
https://android.googlesource.com/kernel/mediatek/+/refs/tags/android-5.1.0_r0.2
So isn't it just a matter of building these source for mtk6580 , or do I miss something in my understand ?

NO.1 comany are not giving their kernel sources, although I've tried.

Thank you for the assistance,

It is using android 5.1? I thought it was 6.0 and I thought the chipset was mt6580.

If no kernel sources, then you would have to use prebuilt kernel.
