Dream never gets old.

$ make tags ARCH=arm

$ make cscope ARCH=arm

Step 1 Switch to the kernel source code directory.

$ cd ./kernel

Step 2 Configure the kernel configuration file.

$ make hi3716c-android_defconfig

Step 3 Compile the kernel.

$ make uImage

Step 4 Copy the generated file to the out directory.

$ cp -avf arch/arm/boot/uImage ../out/target/product/godbox/kernel

Clear the kernel compilation result by running the following command:

$ make distclean

Step 1. Switch to the fastboot source code directory.

$ cd bootable/bootloader/fastboot3.0/

Step 2. Obtain the configuration file corresponding to the board.

$ cp ./lowlevel_reg_info/hi3716cdmoverb_hi3716cv100_ddr3_1gbyte_8bitx4_4layers.reg ../.reg

Step 3. Compile the fastboot

$ make ARCH=arm CROSS_COMPILE=arm-hisiv200-linux- godbox_config

$ make ARCH=arm CROSS_COMPILE=arm-hisiv200-linux- 

Delete the fastboot compilation result

$ make ARCH=arm CROSS_COMPILE=arm-hisiv200-linux- distclean

Step 4. Burn into SPI Flash

fastboot# tftp 0x81000000 fastboot-burn.bin

fastboot# sf probe 0

fastboot# sf erase 0 0x00070000

fastboot# sf write 0x81000000 0 0x00070000

[Error] 

Fedora 10에서 wpa_supplicant 빌드시, 아래와 같은 Error가 발생하였다. 

[Solved]

bison tool의 version 호환성 때문에 발생하는 error이다. 

아래와 같이 bison source code를 build & install해 준다. 

Download source

# wget http://ftp.gnu.org/gnu/bison/bison-2.5.1.tar.gz

Extract tar

# tar –xvzf bison-2.5.1.tar.gz

Build & Install

# cd bison-2.5.1

# ./configure

# make

# make install

Downloading a kernel source for Nexus 10

Ensure that the prebuilt toolchain is in your path

Building a manta kernel

we would build the manta kernel using the following commands:

The kernel for mantaray is device/samsung/manta/kernel

The image is output as arch/arm/boot/zImage. You may copy it as device/samsung/manta/kernel.

Creating a boot.img

Copy a image to ~/aosp_android-4.2.1_r1.2/out/target/product/manta directory.

Ensure that the mkbootimg binary is in your path

Move to ~/aosp_android-4.2.1_r1.2/out/target/product/manta/ directory.

Create a boot.img

Flashing a device

Once the device is in fastboot mode, run

Build environment

+ Operating system -- Tested on Ubuntu 12.04 and 12.10 (64bit)

+ Terminal

+ Decent hardware (minimum of at least a dual core CPU and 4 GB of RAM)

+ Optimally have an SSD (standard mechanical drives work as well but slow down the process drastically)

+ Must have required packages for building installed, I will list them further down

Installing JDK

The Sun JDK is no longer in Ubuntu's main package repository. In order to download it, you need to add the appropriate repository and indicate to the system which JDK should be used.

Java 6: for Gingerbread and newer

Required packages

Getting the source

+ Make directory for repo binary

+ Add directory for repo binary to your path

+ Download repo binary and place it in the proper directory

+ Give the repo binary the proper permissions

+ Create directory for where the AOSP repo will be stored and synced

+ Move to our new AOSP directory

+ Initialize the AOSP repo and download the manifest

+ Sync AOSP source

Getting the binaries

+ Obtaining proprietary binaries

Download a binary hardware support files for Nexus 10 that are available for users of the Android Open-Source Project.

Nexus 10 binaries for Android 4.2/4.2.1 (JOP40C and JOP40D)

# cd  ~/aosp_android-4.2.1_r1.2

1. Audio Processor

2. Wi-Fi, Bluetooth, NFC

3. Graphics

+ Extracting the proprietary binaries

Each set of binaries comes as a self-extracting script in a compressed archive. After uncompressing each archive, run the included self-extracting script from the root of the source tree, confirm that you agree to the terms of the enclosed license agreement, and the binaries and their matching makefiles will get installed in the vendor/ hierarchy of the source tree.

Start the build

If you have patience and have no build errors, you'll end up with a flashable binaries in ~/aosp_android-4.2.1_r1.2/out/target/product/manta

Flashing a device

Set the device in fastboot mode if necessary.

An entire Android system can be flashed in a single command: this writes the boot, recovery and system partitions together after verifying that the system being flashed is compatible with the installed bootloader and radio, and reboots the system. This also erases all the user data.
