Downloads (RC1)
Just to make it clear I'm not responsible for whatever damage this could possibly cause to your device. I

You must update to official android6.0 first! - For updating an already modified device to the android6.0 see:
http://forum.xda-developers.com/showpost.php?p=69383769&postcount=303
I strongly recommend to use this one:
Huawei P8 Firmware (GRA-L09, Android 6.0, EMUI4.0, C432B321, Nordic European)
mega.nz mirror
Or at least any B321 release.

Hello, I would have great interresse on a CM-Rom for the P8 and many other users also. Maybe you could upload the current state here once, so that other users could share their knowledge with

Hi, nice to see another dev who try to compile cm.
Could you upload your Sources to github? It would be easier to help.

 

[nexolight]

@lataldragon & blackball
Currently I'm working with my own gitlab and made some modifications to the build environment to make it compile. Changes are heavy right now (a huge mess) and I'd rather upload it later when I have a stable base.
In addition I don't feel conftable to share my device tree and modifications right now. As I said I'd like to get it to work with as less help as possible and archived something up to now; I'm not the best teamplayer and would barely accept help until I'm not completely stuck. However I will upload it so as soon as it get's past the bootlogo.

Not sure how much it will take but as I said I'm working like a full time job on it (8 1/2h per day).

The state is the same like yesterday except that I got a bith further with zygote. At the moment I'm stuck somewhere in the init process (no further errors, no kmsg). It seems that the crucial services would start up fine if I start them by hand but that should happen automatically. I'm still using most of the 5.0 ramdisk since I started with the files from the 5.0 rom and later switched to the 6.0 files. It could be the issue (working on it, was to lazy until now) but they don't look that different. I will just check all these services in the init.

That's what happens when I unmount /storage (have to correct that anyway) and then start zygote by hand:

Edit: Ok it looks a bit better now with the 6.0 ramdisk as base

No problem

 

[dariusz666]

Hope you will meke it. Stock ROM is so heavy if you use lot of apps. I cross fingers for you.

 

[flamelab]

You can collaborate with this other XDA member who tries (tried?) to make a CM port, to avoid duplicate work, if any.

fisher6 is actually working on AOSP port but they can share some solutions for sure (RIL, camera fix, kernel? and more). @nexolight please have a look at the kernel sources linked in the above thread

 

[nexolight]

@AD2076
I did and it wasn't that helpful. At the end I patched the official kernel for my purposes. The kernel isn't a problem anymore.
@flamelab
It will be a duplicate of work which isn't that bad at all. I wouldn't learn it otherwise and 2nd I may find a better solution which I wouldn't find if I take the work from other people. At the very end we can just take the better one. For me this is primary a learning project. Altough I'm almost forced to do it since my old phone is almost dead.
@dariusz666
yep 2.8GB at least- CM is around 1GB. However the main reason I started porting CM to this was the AGB from Huawei.

@nexolight glad to hear kernel is ok.
I am available for testing if you need it.

 

[nexolight]

Bit more patience please I will upload the stuff to work together when I get past the bootlogo. At the moment there's no usuable build to test

I said I am available just for you to know.
I am not in a hurry and it wasn't my intention to put you in a hurry

Here some more logs. I'm not too familiar with that stuff so one of you may give me a hint faster than I find the cause:
http://pastebin.com/raw/0sTM3EfS

The phone is bootlooping it isn't the full log but the same messages again and again. Guess something related to JNI

Edit:

/*
 * Register several native methods for one class.
 */
static int registerNativeMethods(JNIEnv* env, const char* className,
    JNINativeMethod* gMethods, int numMethods)
{
    jclass clazz;
    clazz = env->FindClass(className);
    if (clazz == NULL) {
        ALOGE("Native registration unable to find class '%s'", className);
        return JNI_FALSE;
    }
    if (env->RegisterNatives(clazz, gMethods, numMethods) < 0) {
        ALOGE("RegisterNatives failed for '%s'", className);
        return JNI_FALSE;
    }

Did you included the vendor blobs?

ofc ^^ and I'm not missing that. But anyway is the camera stuff critical to boot up the system? However this is releated to another library where this one depends on. I didn't tried or included all of them:

This is most likely the same issue.... however I don't want to edit the build environment even more there must be a clean way to do this or just an alternate.
I'm new to porting devices so what is the usual way to alter the framwork source provided by the cm build environment?

This "print_powerlog_native" function comes from at least 1 shared library I can't omit.

You have probably already seen this, but just in case... hope this helps

These don't even work with the 5.0 rom for cyanogenmod for me (6.0 is even more different) and I don't want to add these vendor files in bruteforce mode if you know what I mean
In my case I had to replace the libandroid_runtime.so and there this native method is referenced. The solution in the link I posted before would work pretty well I guess this is just a non-standard function I'd have to add and the problem would be solved. However I'm pretty sure the ndk has a standardized way to do this without editing these files directly. To my point of undersanding editing the build environment is a no-go to make it official.
