* Outline for bc10/prebuilt-20110107 [#qdcd7aa4]
>
COLOR(red){bc10/prebuilt-20110107 is based upon AOSP android-2.2_r1.1}~
~
This article provides the detail explanations of the bootable prebuilt image, android-2.2_r1.1 prebuilt image. This~
prebuilt image is basically a modified and extended version of the bootable image for [[bc10/froyo]]. The first half~
of this section shows how to build the bootable image, and the second half explains how to create a bootable SD~
card, placing the prebuilt image on a the SD card.~
>
- [[The instructions of how to create the prebuilt image]]~
This section provides the instructions of how to create an development environment for '''prebuilt-20110107''', the~
building method of '''prebuilt-20110107''', and the addition of Wifi driver for '''prebuilt-20110107'''. This explains~
how to create the prebuilt image.~
- [[The instructions of how to place the prebuilt image]]~
This section shows that how to download the image of '''prebuilt-20110107''', [[bc10-boot-sd-image-release20110107.tar.gz]]~
and how to place the images into a SD card. This section shows how to make a SD card bootable.~
* Instructions of creating prebuilt image [#ce1abbc7]
* Developing environment [#kad9d6e0]
>
To create the development environment, these three items are really critical.
- OS: Ubuntu 10.04 (32bit version)
-JAVA: java 1.5x
- Android Version: android-2.2_r1.1
** Installing packages [#hda29187]
>
Obtain the required packages from the repository of ubuntu and instal the packages.~
$ sudo apt-get install git-core gnupg flex bison gperf libsdl-dev libesd0-dev \
libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev uboot-mkimage
** java5 [#m66c007f]
>
Since Ubuntu 9.10 sun-java5-jdk, which is critical to build Android, has been removed from the repository of ubuntu.~
An old repository is temporarily added to '''/etc/apt/source.list'''.~
$ sudo vi /etc/apt/sources.list
>
## respective vendors as a service to Ubuntu users.
deb http://archive.canonical.com/ubuntu lucid partner
deb-src http://archive.canonical.com/ubuntu lucid partner

deb http://archive.ubuntu.com/ubuntu lucid-security multiverse
+ deb http://us.archive.ubuntu.com/ubuntu/ jaunty multiverse
+ deb http://us.archive.ubuntu.com/ubuntu/ jaunty-updates multiverse
After adding the old repository, acquire the information of repository by applying '''apt-get update'''. Then, install~
'''sun-java5-jdk'''.~
$ sudo apt-get update
$ sudo apt-get install sun-java5-jdk
After completing the installation, the added repository is removed. This prevents accidentally installing old packages.~
$ sudo vi /etc/apt/sources.list

Once again, applying '''apt-get update''', obtain the present information of the current repository and restore the~
original present depository.~
$ sudo apt-get update
* Obtaining Android source file [#z0b21cb1]
** Setting up repo [#pf4dd7f9]
>
Configure '''repo''' for obtaining the source code of android.
$ cd ~
$ mkdir bin
$ curl http://android.git.kernel.org/repo >~/bin/repo
$ chmod a + x ~/bin/repo
>
As using Ubuntu, once log-out and then log-in, PATH is going through '''~/bin''' automatically. Prefer to stay~
log-in, set the PATH to '''~/bin''' flowing directions shown below.~
$ export PATH=~/bin:$PATH
** Initializing repo [#cc4bddcf]
>
Create a directory called '''bc10''' for the source file, and execute '''repo init''' to download '''android-2.2_r1.1 branch'''~
to the '''bc10''' directory.~
$ cd~
$ mkdir bc10
$ cd bc10
$ repo init -u git*//android.git.kernel.org/platform/manifest.git -b android-2.2_r1.1
** Adding local_manifest.xml [#b956a09c]
>
The source code that can be downloaded with the '''android-2.2_r1.1 tag''' does not include ALSA. To use ALSA as audio~
library, modify the '''local_manifest.xml''' for adding ALSA and its related files, and make the source code of the ALSA~
file obtainable. To obtain the files, create a '''local_manifest.xml''' under the directory of '''bc10/.repo/''' and modify~
it as shown below.~
>
The android-2.2_r1.1 specific ALSA related files have not been tagged out yet. This time, the ALSA of '''Froy branch is used'''~
for android-2.2_r1.1.~
$ vi .repo/local_manifest.xml
>
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project path="external/alsa-lib" name="platform/external/alsa-lib" revision="froyo"/>
<project path="external/alsa-utils" name="platform/external/alsa-utils" revision="froyo"/>
<project path="hardware/alsa_sound" name="platform/hardware/alsa_sound" revision="froyo"/>
</manifest>
** repo sync [#d6c91d14]
>
After adding '''local_manifest.xml, execute '''repo sync''', and obtain the source code of android.
$ repo sync
>
The total size of the files is from 2 to 4GB. Download time highly depends on the speed of network.
* Applying the build configuration file of bc10 [#t2e4868d]
>
The patches and configuration files, which Optimize and build android-2.2_r1.1 for bc10, are downloaded from the~
repository of github by the command of '''git clone'''. Then apply the patches and configuration files by the command of~
'''patch_to_android-2.2_r1.1_for bc10/bc10-patch.sh'''.~
$ cd ~
$ git clone git://github.com/bc-dev/path_to_android-2.2_r1.1_for _bc10.git
$ cd patch_to_amndroid-2.2_r1.1_for _bc10
There are no specific directory for the downloaded patches and configuration files, which are obtained by '''git clone''',~
but before applying these patches and files, make sure that the environment variables in '''bc10-patch.sh''' are matched with~
the PATHs of these files.~
$ vi bc10-patch.sh
>
### Settings
ANDROID_DIR=${HOME}/bc10
SETUP_DIR=${HOME}/patch_to_android-2.2_r1.1_for_b10
PATCH_DIR=${SETUP_DIR}/patches-for-bc10
After checking the PATHs of the files are equal to the the environment variables in '''bc10-patch.sh''', execute '''bc10-patch.sh'''.~
$ ./bc10-patch.sh
* Android build [#ga389d12]
>
Set up the environment for bc10
$ cd ~/bc10
$ source build/envsetup.sh
$ lunch bc10-eng

** Crating image [#f5fad18f]
>
After build is completed, relocate the binary of '''userland''' to a bootable place. '''mkbc10-image.sh''' is used for setting up~
'''userland'''.
$ cd ~/patch_to_android-2.2_r1.1_for_b10
$ ./mkbc10-image.sh
Execute commands above, '''bc10-image''' is created under the directory of '''bc/out/target/product/bc10/'''. Under the directory of~
this '''bc10-image''' '''android userland''' will be placed.~

* Kernel build [#g973eb02]
** Configuring environment variable [#p159c559]
>
'''x-loader''', '''u-boot''', and '''kernel''' are required for booting bc10. These are built with '''toolchain''', which is distributed
with the~
source code of android. '''toolchain''' used here is located at the directory, '''prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin'''.~
The environment variable is needs to set for the cross compile as this toolchain build these files.~
$ export PATH=/home/beat/bc10/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin:${PATH}
$ export ARCH=arm
$ export CROSS_COMPILE=arm-eabi-
** kernel [#n70ef041]
>
$ cd ~
$ git clone git://gitorious.org/~bc-dev/rowboat/bc10-rowboat-kernel.git bc10-rowboat-kernel
$ cd bc10-rowboat-kernel/
Shift to the release branch for bc10.
$ git checkout -t -b bc10-2.6.32 origin/bc10-2.6.32
$ make omap3_bc10_defconfig
$ make uImage
$ make modules
After build is completed, '''uImage''' is created at the directory shown below.
$ ls ~/bc10-rowboat-kernel/arch/arm/boot/
Image Makefile bootp compressed install.sh uImage zImage
* Building USB Wifi (RT3070USB) driver [#w229d145]
>
To work with USB Wifi devices, a Wifi driver, '''RT3070USB''' is added. The devices listed below have been tested and confirmed that~
the devices are working appropriately.~
COLOR(red){Some devices are still underdevelopment, please do understand that the contents may change without advanced notice.}
Maker Serial Number Device ID Memo
PLANEX GW-USMicroN-G 2019:ED14
Logitec LAN-W150N/U2IPH 0789:0164
Logitec LAN-W150N/U2BK 0789:0168
Buffalo WLI-UC-GNM 0411:01a2
Buffalo WLI-UC-G301N 0411:016f　 The performance of Baffalo WLI-UG-G301N is only confirmed as it is connected to AC powered hub.
Buffalo WLI-UC-GN 0411:015d
In this section, the explanation is specifically targeted at Baffalo's and Logitec's Wifi devices.
>
The driver, '''2010_0831_RT3070_Linix_STA_v2.4.01_DPO.bz2''', is downloaded from [[PALINK Web>http://www.ralinktech.com/support.php?s=2]]. The driver used here is~
a Linux driver. Also, a firmware, '''RT28xx/RT30xx''' USB series (RT2870/RT2770/RT3572/RT3070) are required. To download~
the source code and/or firmware, input user name and email address for downloading the files. Assume that the downloaded~
files are placed at the directory of '''/home/beat/'''. '''toolchain''' used here is the same '''toolchain''' which is used for building kernel~
and located at the directory of '''prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin'''. The firmware is modified for bc10. '''prebuilt image'''~
does not produce any debug logs since a part of '''config.mk''', which is located at the directory of os/linux/config.mk, is set as~
'''WLAGS += -DCONFIG_STA_SUPPORT'''. As debug logs are not displayed, critical logs may be missed. Please be careful.~
>
To produce debug logs, set up the part of '''config.mk''' as '''-WFLAGS += -DCONFIG_STA_SUPPORT -DDBG''', then, rebuild~
the source file and place the file again. During the redoing process, debug logs are output. There may be too many logs,~
and these logs make to harder to work on this process.~
>
To apply the patch, '''RT3070USB.diff''', this becomes capable of cross-compile for bc10.~
The contents of the patch are:~
- Add the compile configuration for bc10 (platform, PATH of toolchain, and the configuration of compile frags.
- Set up the region of firmware to Japan, and change the examples of each section.
- Add USB Wifi vender ID and product ID.

Since X-Loader (MLO) is the first boot loader, there are strict order to place the file to the SD card. Please follow the~
instructions, carefully.
- After formatting FAT32 directory, '''MLO''' is placed first.
- MLO is put at the top directory in the partition.
$ [cp MLO /media/FAT32/]
There are no specific rules for how to put other files. Copy these files on the SD card as they are.
