Hi, may I ask somebody experienced with ROM building, if it is possible to build fully functional and stable build from AOSP sources if i have kernel sources for my device from vendor?

Hi, yes. I've compiled lollipop nexus4 from aosp in ubuntu 14.04.1 x64 in vmware.
I've downloaded the source, included the proprietary files, and compiled android, compiled with make and make otapackage to generate the zip.
After that i've rooted the device, installed twrp.
Finally, i've downloaded the source kernel and compiled to generate the .img. I've flashed this to the device with fastboot, and
yeeeeeeh perfect!!!
obviously, after this, i've downloaded the gapps and installed.
But, which version would you compile? And which device? All the sources are available and open source?
i wana make AOSP build for Huawei Ascend G6, I have only kernel sources from vendor... I suppose that kernel will work with any version of android or not?

Ok, you have the sources, very good.
mmm, i'm not sure that every kernel + android combinations work perfectly together.
For example, on my nexus4 i've kernel 3.4 and lollipop. Now, if android lollipop requires some modules/functionalities/"other magic stuff" to work properly from the kernel, and you install kernel 2.x.x without this feature, probably you'll have problems.
I mean, i'm not sure, but is only a logic hypothesis.
You can solve this problem using the latest official version of android from Huawei and your compiled kernel from Huawei sources. If this works, try to update android to another version with a custom rom. It works? Perfect!, It not works? Damn, restore the backup and use another older android version
To build android/kernel you must transform into a researcher :laugh:

Can I use the stock kernel (Froyo) and the binary drivers that comes with the stock and use the aosp source code and build higher version of the platform (gingerbread, icecream ) as and when they are available?
Why do the kernel needs a change when upgrading from one version of android to another, the hardware doesn't change anyway.

OKAY LET´S GO MAN
you can´t port a kernel from froyo to ginger for example because the kernels are created with diferents codes...
if you want to create a custom kernel from a stock kernel you needs the "privative drivers" and the source code for to do this... gingerbread has another source code than ice cream (still closed source)
the same thing happens with AOSP (cyanogenmod for example) but they uses a pure LINUX code for to create a custom kernel..
AOSP also needs the source code of the android version for that are creating the kernel.
and the kernel need to be changued between android versions because are not compiled of equal way.
ext4, task admin... and H/W don´t works equal between android versions
Hi all,
I've a question for you guys.
I've a SG3 (i9300), I'd like to know if using the cyanogen device tree for my device (located here) is possible to build AOSP source code.
if yes, then it looks like that would be possible to compile Lollipop AOSP for my device.. am I right ?
Thank you very much.
Cyanogen IS AOSP... Lol. Its AOSP with added features. If that's not an Android 5.0 lollipop kernel source, then it won't boot out of the box. Your best bet would be to get some Android 4.4 kernel source and do ramdisk edits and what not needed to get an Android 5.0 ROM booting. Alternatively, if your device is CM supported, I know they were talking about releasing CM12 soon, you could just hold out to see if your device is supported. Outside of CM, many custom ROMs (AOKP, Pacman, etc.) Take it upon themselves to release ROMs as well. Example: PACman had a 4.4 custom ROM out and in circulation, even before cyanogenmod, so u never know!

Hello, thanks for your answer.
I'd like to know this only for learning purpose, I'm not going to compile the AOSP
What I don't understand, is why adding the device tree to the lollipop AOSP is not sufficient to boot out of the box, can you please explain this in details ? Many thanks.
Hi,
I'm on OmniROM 4.4.4 with Franco r63.
I want to apply this patch: https://github.com/pelya/android-keyboard-gadget
but I can't seem to find any way to download the r63 release source.
I should mention that I'm new to compiling android kernels (but I have compiled regular linux kernels back to 2.0.x versions)
Thanks.
I have a BLU Energy X 2 running the MT6580 chipset, with kernel version 3.10. I was looking into porting CyanogenMod12.1, however there is no device tree, as the kernel version is not updated enough. Is it still possible to port the ROM? I also don't have the vendor tree, how would I get that?
Thanks, Nate

Hello,
You need to generate the blobs for the vendor. Also you need a working device tree and kernel for it.
You can refer here Guide to Port MTK Roms for more information.

I got the source code form opensource.samsung.com and I compiled the kernel successfully.
I want to know that how do I use the kernel to build AOSP for my phone?
And the samsung kernel is based on Android 6.0.1, can I port the latest Android version to my phone?
