New Custom Rom with new Custom Kernel from scratch

zrox

Hi all,

I build a complete new Android Image from scratch, approx. clean (no extereme special apps added) but with some changes to the stock image.

- rebuild 3.4.39 kernel with hdi raw, joystick and bluetooth support (bt does not work yet bt-stack needs to changed to bluez)
- patched libinput.so (K400 Keyboard support and also others)
- Xbox 360 controller support works out of the box
- wifi 8188eu and ethernet works well
- bluedroid (included but not useful atm. because don't work with bt-usb, needs to be changed to bluez)
- live wallpaper support
- filemanager and stutdown app
- bigger system and data partition
- changed default boot screen




Download

Download the complete SDK.



Compile you own Android image:

1. Step we need Ubuntu 12.4 x64 I work only native, not in a VM so I don't know if it works perfect in a VM and a newer version of Ubuntu will not work..

2. open a Terminal and type

1. sudo -s

Copy the Code

and

1. apt-get update && apt-get upgrade

Copy the Code

install needed packages:

1. apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev libc6-dev \
   
2. lib32ncurses5-dev ia32-libs   x11proto-core-dev libx11-dev lib32z1-dev libgl1-mesa-dev g++-multilib \
   
3. mingw32 tofrodos python-markdown libxml2-utils libglapi-mesa:i386 uboot-mkimage
   
4. 
   
5. and we need java .
   
6. 
   
7. sudo add-apt-repository ppa:webupd8team/java
   
8. sudo apt-get update
   
9. sudo apt-get install oracle-java6-installer

Copy the Code

Download the compete android SDK.

and now lets start, extract it

1. tar xjf v2.0_A20-Kernel-only.tar.bz2

Copy the Code

switch into the kernel directory

1. cd V2.0_A20/lichee/linux-3.4/

Copy the Code

copy the kernelconfig file

1. cp arch/arm/configs/banana_pi_config .config

Copy the Code

configure the kernel if you like to change it

1. make ARCH=arm menuconfig

Copy the Code

and save it.

now go back in the lichee directory

1. cd ..

Copy the Code

and build the kernel

1. ./build.sh -p sun7i_android

Copy the Code

the kernel will be compiled.

if all is ready done, you will find a new directory named out

1. ls out/android/common/

Copy the Code

in this folder you will find the new compiled Kernel and the modules (just for the info   )

now lets compile android.

1. cd ../android

Copy the Code

1. source build/envsetup.sh

Copy the Code

1. lunch

Copy the Code

Select 15 sugar_bpi-eng

and copy the kernel and modules with

this takes some hours...

if already is done create the image

1. pack

Now burn the new Image with PhoenixCard and have fun

thats it.

Thanks very much for your efforts. I just downloaded it and i am testing it. As it seems it doesnt accept any of my USB input devices sadly. My regular cabled mouse is not working, neither my Logitech K400

vicedens2002

Is it possible to enable bluetooth support ? And please can you make the devices to work which are blacklisted in the kernel ?

zrox

Hi all,
@Adromir, it sounds strange, I have on my banana pi with this image a
A4tech usb-cable mouse, Minix A2 Airmouse and a 360 controller running and all
this input devices works fine. Do you have a possibility to check with a Linux
Distro which modules will be load on your hardware? Probable your power supply is
not strong enough?

@vicedenes, could you explain me which blacklisted devices did you mean?
Yes I think bt support is also possible, but we will see. But plug and play
Is with Android and a lot of hardware not possible, for many devices the
Modules must load manually or with a script.

@zrox: I am not an experienced user yet, i am trying to get into it. How do i check that out?

zrox

Install a Linux distro on a SD card , check if your hardware works, open a terminal and type

1. lsmod

Copy the Code

And please post the output here.
That's it

Adromir

Oh the hardware Works. The Mouse works on the original Android 4.2.2 image and the K400 works in the Android 4.4 Beta1 image

zrox

yes, I mean check if your hardware works when you start your banana pi with the linux distri (for example Lubuntu or Respbian...)
