T428 Study and Research on Experimental Firmwares

[Guest]

Strauzo, if you can suggest what error I'm making in my attempt to compile source then I can try a few options whilst you are away

I'm currently using a 64bit VM and can compile the source code without modification. However the kernel produced is not binary identical with the one produced and doesn't boot

For clarity these are my build steps:

• Installed Ubuntu 13.10 amd64
• Got all the required libraries and toolchain
  • sudo apt-get install git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.8-dev build-essential zip curl libncurses5-dev zlib1g-dev gcc-multilib g++-multilib sharutils lzop gcc-arm-linux-gnueabi
• downloaded the tarball of MK908 (and MK908 II) kernel sources to ~\android\kernel
• renamed the suppiled kernel to kernel.img.orig
• ran "make clean"
• ran "make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- kernel.img

I get successful compile and kernel creation. However, if I do a binary compare (cmp -l kernel.img kernel.img.orig) of the original kernel and the one I just built and just about every byte is different

kernel doesn't boot.

First the version that you are build is 3.0.36 and must be 3.0.36+

After you must use rkcrc -k ./Image ./yourkernel.img

Thank you for that. I'll try as soon as I get to my hotel this evening.

You are in las vegas ? Tomorrow i go to Hong Kong

Haha nothing so exciting. I live in Wales (uk) and am working in a place near Coventry.

Yeah I've had all the "being sent to Coventry" jokes.

I'm down for Canada next month. Hope it warms up!

Anyway, back on topic I spun up my laptop during lunch and looked at (a) RKCRC and (b) 3.0.36+ compile

From my tests it seems mkkrnlimg and RKCRC do the same thing. Obviously I'll use RKCRC

What I don't get is how to "build 3.0.36+ instead of 3.0.36". I tried editing the Sublevel= in makefile to 36+ but this just confuses the preprocessor. I also tried adding a + to extended version= but this made no difference

To strauzo
I used yours kernel and boot plus the system img from Bob Finless 2.0 doesn't boot.
With is full setup my T428 boots ok, but wifi is gone, no issue i have a usb/ethernet that is working and manage to go play store and load antutu score 12K but it seems fast woking and opening stuf.
Tried xbmc but servers are down. Tomorrow another day and going to try my Gasia PS3 fake controller.....

Got it!!!

Have compiled a bootable kernel. :banana:

Will work on variants from here. First off - overclocking and 1080p

Can someone test the attached T428 kernel to make sure it works ok on other sticks. It does boot okay on mine and wifi works

Congrats!

I knew you would get it!

So, what steps did you end up doing?

Signature? Signature!

I reset the .config file with the default using Make.

Make RK3188_sdk_android-4.4_defconfig

Then

Make nconfig (To change wireless to AP6330)

Then

Make kernel.img


Using my ipad so apols for any stupid ios spelling 'corrections'

As you can see in new ROM development forum, I've built a native 1080p T428 compatible kernel with mild CPU O/C (1.7 GHZ) and 667 MHZ RAM

Antutu 20,500

FYI this kernel works on my T428 wifi and everything with my KitKat 2.0 ROM.
It's 720P.
